Glossary

  • Psychoacoustics is the science of how humans perceive sound. It explores how our brain interprets audio stimuli based on physical properties (frequency, amplitude, phase) as well as cognitive and emotional factors. In music production, psychoacoustics helps explain phenomena such as : Frequency masking, Spatial localization, Perception of stereo, loudness, clarity, Effects like auditory illusions, phantom center, and perceived width
  • ADSR stands for Attack, Decay, Sustain, Release — the four stages of a sound envelope commonly found in synthesizers. ADSR shapes how a sound evolves over time — it’s an essential tool in sound design. Attack: how long it takes for the sound to reach full volume after a note is pressed. Decay: how long it takes to drop from the peak to the sustain level. Sustain: the level maintained while the note is held. Release: how long it takes for the sound to fade out after the note is released.
  • The Amen Break is a 6 second drum solo taken from the track "Amen, Brother" by The Winstons (1969). It became one of the most iconic and widely used samples in music history. Especially in genres like hip-hop, jungle, breakbeat, drum and bass, and more. Sliced, rearranged, and endlessly transformed, it’s a cornerstone of sampling culture and has left a lasting impact on electronic music.
  • The amplitude envelope (or Amp Envelope) controls how a sound’s volume changes over time. It typically has four stages: Attack, Decay, Sustain, and Release (ADSR).  These parameters shape the dynamics of a sound — for instance, a fast attack creates a punchy sound, while a long release results in a smoother fade-out.

  • An arpeggio is a sequence of notes from a chord played one after the other, rather than all at once. It can be performed manually or generated by an arpeggiator, which is commonly used in electronic music.  Arpeggios add motion, rhythm, and melody to chord progressions, whether in a smooth or punchy, rhythmic style.

  • Arrangement refers to the organization of a track’s different elements over time.  This includes the intro, breaks, builds, drops, and the outro.  It’s a key stage that turns a loop or musical idea into a full structure, ready to be performed or released. Read More
  • Audio can be a recording (digitized) made at home (voice, guitar, percussion… using an audio interface), in the field (using a field recorder), or a sample created by someone else and loaded into a sampler — this is referred to as a one-shot. When played in a loop and synchronized to the tempo using time-stretching algorithms, it is called a loop. (Often in .wav or .aiff)
  • Automations let you automatically change a parameter over time (volume, panning, filters, effects…). They appear as curves or points in your digital audio workstation (DAW). Automations bring a track to life, help create transitions, add dynamics, and highlight key moments in a production.
  • Aux, short for auxiliary, refers to a channel used to send part of an audio signal to an external effect or processor. such as reverb, delay, or parallel compression. This allows multiple tracks to share the same effect while maintaining individual control.  Aux buses are essential in mixing for creating sonic cohesion and saving processing power.

  • A backup is a safety copy of your files, projects, or settings, stored in a different location than the original (external drive, cloud, USB stick, etc.). In music production, regularly backing up your work helps prevent data loss due to crashes, bugs, or accidental deletion. It’s a crucial habit to protect your creative output over time.
  • In music, a bar — or measure — is a unit of time that groups a certain number of beats, depending on the time signature of the piece (e.g., 4/4 means 4 beats per bar). Bars help structure rhythm and organize music. They are used to mark sections of a song (intro, verse, chorus…) and to align instruments or loops. In digital audio workstations (DAWs), bars are visible on the timeline and are essential for arranging and composing.
  • A bass line is a sequence of low-pitched notes that supports the harmony and rhythm of a track. It can be played by an electric bass, a synth bass, or another low-end instrument. The bass line drives the groove, reinforces chord progressions, and often works closely with the drums to bring movement and energy to the music.
  • Beatboxing (or human beatbox) is the art of mimicking drum sounds, percussion, and even instruments or effects using only the mouth, tongue, and voice. Originating in hip-hop culture, it has evolved into a full-fledged vocal discipline combining rhythm, groove, and performance. Beatboxing can be used live, in the studio, or as a creative rhythmic foundation in music production.
  • Beatmaking is the art of creating rhythms and instrumentals, often using production software (DAW), samples, drum machines, or synthesizers. The beatmaker builds the rhythmic and harmonic foundation of a track, especially in genres like hip-hop, trap, R&B, and electronic music. It’s a creative craft that blends groove, sound design, arrangement, and a strong sense of sampling. Read More
  • Bit depth defines how accurately the amplitude of an audio signal is captured during analog-to-digital conversion. The higher the bit depth, the greater the dynamic range, allowing for more detail and less background noise. For example, 16-bit is standard for consumer audio, while 24-bit is widely used in production for higher sound quality.
  • A borrowed chord is a chord temporarily taken from a related key (usually the parallel major or minor). It’s used to enrich the harmony and introduce unexpected color into a progression. For example, in a major key, you might borrow a chord from the parallel minor to create a darker or more expressive mood.
  • Bounce refers to the process of exporting or rendering an audio project into a single file, usually in WAV or MP3 format. It can apply to a full mix, an individual track, or a group of tracks. Bounce in place also describes converting a MIDI or effect-heavy track into audio within the session. It’s a key step for sharing, archiving, or finalizing a track.
  • Brass synth is a synthesizer sound designed to imitate or evoke brass instruments like trumpets, trombones, or horns. It can be realistic or stylized, often used for its punchy attacks and bold character in genres like funk, synthwave, electro, or pop. Brass synths bring power, presence, and a retro or orchestral flair depending on the context.
  • A bus is a virtual channel in a digital audio workstation (DAW) that allows multiple tracks to be grouped and processed together. You can apply effects (like compression or reverb) or control the overall volume of a group (e.g., drums, vocals, synths). Buses help organize your session, optimize audio processing, and make the mix more cohesive.
  • A choke group is a feature in samplers and drum machines that prevents certain sounds from overlapping. When one sample in the group is triggered, it automatically cuts off the others. This mimics the natural behavior of instruments like hi-hats, where a closed hit silences an open one. It’s a useful tool for keeping drum patterns tight and realistic.
  • A chord is a group of at least three notes played at the same time. Chords are the foundation of musical harmony. They can be major, minor, diminished, or augmented, each conveying a specific mood.  Chord progressions provide the harmonic structure of a song or track. Read More
  • Comping (short for composite take) is an editing technique used to select the best parts from multiple takes of a recording to create a final, polished version. Commonly used for vocals, solo instruments, or complex performances, comping helps you get the best possible result while keeping a natural feel. Most modern DAWs offer comping tools with take lanes, quick selection, and automatic crossfades for seamless editing.
  • Compression is an audio processing technique that reduces the difference between the loudest and quietest parts of a signal. It works by lowering the volume of sounds that exceed a set threshold, helping to balance the dynamics of a track or mix. When used properly, compression can make a sound tighter, punchier, or more consistent. It’s a key tool in music production, whether on vocals, drums, or the final master.
  • Convolution reverb is a type of digital reverb that uses a real-world audio recording called an impulse response (IR)— typically captured in a room, hall, or through a physical reverb unit (like a concert hall or plate). This IR is then mathematically applied to any audio signal to reproduce the exact reverb characteristics of that environment. Convolution reverb delivers highly realistic results, making it perfect for sound design, film, acoustic music, or anytime you want to place a sound in a believable space.
  • A de-esser is an audio processing tool designed to reduce sibilance—the harsh sounds produced by consonants like S, CH, or T, which often stand out too much in vocal recordings. The de-esser works like a frequency-specific compressor, usually targeting the 4 kHz to 10 kHz range. When set properly, it smooths out the voice without dulling it, resulting in a more pleasant and balanced sound.
  • Decibels (dB) are a unit of measurement used to quantify sound level or audio signal intensity. It’s a logarithmic scale, meaning an increase of about 6 dB roughly doubles the perceived loudness. In music production, decibels are used to measure volume levels (dBFS in digital, dBu or dBV in analog) to avoid distortion or clipping and to balance elements within a mix.

  • Delay is an audio effect that repeats a sound after a short period of time, creating an echo or sense of space. It can be used subtly to thicken a sound or more prominently for rhythmic or psychedelic effects. There are different types of delay—analog, digital, ping-pong, tape, etc.—each with its own character and behavior.
  • A DAW (Digital Audio Workstation) is a music production software used to record, edit, arrange, mix, and exportmusic or sound. It serves as the central hub of the digital studio, handling audio, MIDI, effects plugins, and virtual instruments. Popular DAWs include Ableton Live, FL Studio, Logic Pro, Cubase, Reaper, Pro Tools, and more. Each DAW has its own strengths (composition, mixing, live performance, post-production…), but all allow you to create music from start to finish.

  • Doubling is the technique of recording or duplicating the same musical part (vocals, guitar, synth, etc.) to make it sound thicker, wider, or more prominent in the mix. It can be done by performing the part again (for a natural, human feel) or by copying and processing the track differently (using delay, panning, pitch, etc.). Doubling is especially common for lead vocals and instrumental leads.
  • In audio effects, dry refers to the original, unprocessed signal, while wet is the processed signal (with reverb, delay, chorus, etc.). The dry/wet control lets you blend the two. For example, 100% wet means you hear only the processed sound, while a 50/50 setting mixes both the original and the effect equally. It’s a key parameter for applying effects tastefully in a mix.
  • Dynamics refer to the difference between the quietest and loudest parts of a recording or performance. Wide dynamics allow for expressive contrast, while limited dynamics create a more consistent sound. In music production, controlling dynamics (using tools like compression or automation) is essential for balancing a mix, adding impact, and guiding the listener’s focus.
  • An equalizer (EQ) is a tool used to adjust the level (gain) of specific frequency ranges in a sound. It can reduce or boost bass, mids, or highs to correct, shape, or enhance an audio signal. There are various types of EQs: graphic, parametric, shelving, and semi-parametric, each offering different levels of control. EQ is essential in mixing for clarifying sounds, eliminating frequency clashes, or highlighting key elements.

  • Eurorack is the most popular standardized format for modular synthesizers. Developed by Doepfer in the 1990s, it has grown into a massive ecosystem with thousands of compatible modules (oscillators, filters, effects, sequencers, etc.) from manufacturers worldwide. Eurorack modules are 3U tall and their width is measured in HP (horizontal pitch). They are mounted in a powered case. Eurorack is beloved for its modularity, compactness, and limitless creative potential.
  • Field recordings are audio recordings made outside of a studio, capturing real-world environments: nature, cityscapes, transportation, human activity, and more. They’re used in music, sound design, film, or podcasts to add texture, realism, or atmosphere. Typically recorded with portable microphones or digital recorders, field recordings are also a rich source of unique samples for creative production.
  • A fill is a short rhythmic or melodic passage, often played on drums or percussion, used to signal a transition between sections of a song (e.g., from a verse to a chorus). Fills can also be created with synths, FX, or other instruments. They add variety, energy, and help guide the listener through the structure of the track.
  • A filter is a tool used to shape sound by reducing or removing certain frequencies. Filters are essential in sound design, mixing, and synthesis to sculpt tone, create effects, or clean up a signal. Low-pass: allows low frequencies through, cuts the highs High-pass: allows high frequencies through, cuts the lows Band-pass: allows a specific range of frequencies through Notch: cuts out a narrow frequency band
  • The Fletcher-Munson curves show how the human ear perceives different frequencies depending on the listening volume. At low volumes, we hear bass and treble less clearly, while at higher volumes, our perception becomes more balanced. These curves explain why a mix may sound different at different listening levels. Understanding this phenomenon is crucial for making accurate mixing and mastering decisions.
  • Four to the floor is a steady rhythm where the kick drum hits on every beat of the bar (1, 2, 3, 4). It’s the signature groove of many electronic music genres, including house, techno, trance, and disco. This simple, driving pattern creates a consistent pulse that makes it ideal for dancing and easy for DJs to mix.
  • Frequency refers to the number of sound vibrations per second, measured in hertz (Hz). The higher the frequency, the higher the pitch; the lower the frequency, the deeper the sound. The human ear generally hears frequencies between 20 Hz and 20,000 Hz. In music production, understanding frequencies helps with EQing, filtering, and mixing sounds so they complement each other instead of clashing.
  • A fugue is a polyphonic musical form based on the principle of imitation. It typically begins with a main theme (the subject) introduced by one voice, then repeated and developed by other voices in an interwoven texture. Each voice maintains its own melodic and rhythmic independence, resulting in a complex and structured composition. Made famous during the Baroque era by composers like Johann Sebastian Bach, the fugue is a highly disciplined form often studied in classical composition.
  • The fundamental is the lowest and primary frequency of a complex sound. It defines the perceived pitch of the sound. Even when a sound contains many harmonics (higher multiples of the base frequency), it’s the fundamental that forms the tonal foundation. For example, in a tone at 440 Hz (A3), 440 Hz is the fundamental, with harmonics layered above. In music production, isolating or enhancing the fundamental helps achieve clarity, tuning accuracy, and low-end strength.
  • Gain staging is the practice of managing volume levels at every stage of the audio signal chain, from recording to mixing, to avoid distortion, noise, or loss of quality. The goal is to maintain a clean, balanced signal with enough headroom for proper processing. Good gain staging ensures that effects like EQ and compression behave consistently and musically throughout the mix.
  • Glide is a term often used interchangeably with portamento in synthesizers. It refers to the smooth transition in pitch from one note to another instead of an instant jump. The glide time can be adjusted to control how fast the pitch moves between notes. This effect is especially popular in monophonic synths, trap 808 basses, expressive leads, and retro analog-style sounds.
  • Glue compression is a type of compression used to “glue” the elements of a mix together, especially on a drum bus or mix bus. The goal isn’t to squash the sound, but to tighten the dynamics subtly, adding more cohesion, punch, and warmth to the overall mix. Inspired by vintage VCA compressors (like the SSL bus compressor), glue compression is widely used in mixing and mastering to create a unified sound.
  • Groove refers to the rhythmic feel of a track — the element that makes you want to move, dance, or nod your head. It’s not just about tempo, but how the elements interact: note placement, timing variations, accents, swing… Groove often comes from the balance between tightness and human imperfection, and it’s a key ingredient in styles like funk, hip-hop, house, afrobeat, and soul.
  • The Haas effect is a psychoacoustic phenomenon where a sound is perceived as coming from a specific direction when it’s slightly delayed in one ear compared to the other (typically between 1 and 35 milliseconds). In music production, it’s used to widen the stereo image without duplicating the signal or adding reverb. For example, delaying a sound by a few milliseconds in the left or right channel can create the illusion of width or directional placement.
  • The term half-beat typically refers to a rhythmic shift where percussive elements (like snares or claps) are played at half the regular rate, while the tempo stays the same. For example, in a 120 BPM track, instead of the snare hitting on beats 2 and 4 (regular time), it hits only on beat 3, giving a slower, heavier, or more laid-back feel. This groove is commonly used in trap, dubstep, and modern R&B. Read More
  • Harmonics are multiples of the fundamental frequency of a sound. For example, if the fundamental is 100 Hz, its harmonics will be at 200 Hz, 300 Hz, 400 Hz, and so on. Harmonics shape the timbre of a sound and help us distinguish a voice, piano, or guitar even if they play the same note. In sound design and mixing, manipulating harmonics (through saturation, distortion, or EQ) adds warmth, character, or clarity to an audio signal.
  • Harmony is the art of combining multiple notes played at the same time to form chords and chord progressions. It’s based on how notes from a scale interact within the key of the piece. Harmony adds emotional depth to music and supports the melody. Understanding harmony helps build strong chord progressions, enrich compositions, and improvise with purpose.
  • Headroom is the amount of space, measured in decibels, between the peak level of an audio signal and 0 dBFS (the digital ceiling). Leaving enough headroom helps prevent clipping, ensures cleaner sound, and gives space for mastering. A common guideline is to keep your mix peaking around -6 dB to -3 dB, allowing for a clear and dynamic final result.
  • Hertz (Hz) is the unit used to measure frequency, meaning the number of vibrations per second of a sound. The higher the hertz, the higher the pitch; the lower the hertz, the deeper the sound. For example, the standard A4 note vibrates at 440 Hz. The human ear typically hears frequencies between 20 Hz and 20,000 Hz. Hertz is a core concept in music, sound synthesis, and audio processing.

  • An Impulse Response (IR) is a very short audio recording that captures how a space or piece of gear (like a room, cabinet, reverb unit, etc.) reacts to an impulse sound (such as a sharp click or sweep tone). This recording is then used to accurately recreate the sonic character of that space or equipment using convolution plugins. IRs are widely used in convolution reverbs, but also to simulate guitar amps, speaker cabinets, and even vintage hardware.

  • An interval is the distance between two notes, measured in whole steps and half steps (tones and semitones). Intervals shape the color and emotion of a chord or melody. For instance, a major third sounds happy, while a minor third feels more melancholic.  Understanding intervals is essential for building strong harmonies and melodies.
  • An inversion is a variation of a chord where the lowest note (the bass) is not the root, but another note from the chord. This doesn’t change the chord’s identity, but alters its harmonic color and voicing. Inversions allow for smoother chord transitions, add harmonic richness, and are widely used in piano playing, arranging, and composing. C major = C - E - G → root position 1st inversion = E - G - C 2nd inversion = G - C - E
  • Latency refers to the delay between an input signal (such as a played note or audio signal) and its corresponding output, either as sound from speakers or as processed data within a digital audio system. In audio production, latency is most commonly introduced by analog-to-digital (A/D) and digital-to-analog (D/A) conversion, buffer sizes in the DAW, and processing time from plugins or drivers. It is measured in milliseconds (ms), and even small amounts can affect performance, particularly during live recording or real-time monitoring. Managing latency involves balancing buffer size for(...) Read More
  • Layering is the technique of stacking multiple sounds or instruments playing the same part to create a richer, more powerful, or more complex sound. In production, you can layer kicks, synths, vocals, and more to combine their strengths (attack, texture, stereo width, frequency content…). Layering is a key technique in sound design and mixing, especially in electronic and urban music.
  • Legato is a playing technique where notes are connected smoothly, with no gaps between them. In MIDI or synthesis, this often means that notes slightly overlap, which can trigger specific behavior—such as smooth transitions between notes (especially in synths or virtual instruments with portamento or legato sampling). Legato playing adds fluidity, expression, and realism to melodic lines.
  • A leveler is a type of automatic dynamics processor that gradually adjusts the volume of an audio signal to maintain a consistent loudness. Unlike a traditional compressor, a leveler works more smoothly and transparently, making it ideal for vocals, podcasts, or solo instruments. It’s commonly used to even out volume fluctuations without squashing the natural dynamics.
  • A loop is an audio or MIDI segment that repeats continuously in a cycle. It can include drums, melodies, basslines, vocal chops, and more. Loops are widely used in electronic music, hip-hop, and modern production to build tracks quickly, create repetitive grooves, or sketch out ideas. A loop can be original (recorded or programmed by the artist) or pre-made (from a sample pack).
  • The Loudness War refers to a mastering trend where the perceived volume of tracks is pushed higher by heavily reducing dynamic range (using compression and limiting). The goal was often to stand out on radio or streaming platforms, but it led to loss of clarity, depth, and listener fatigue. Today, with volume normalization on platforms like YouTube and Spotify, the loudness race is less relevant, and more producers aim for balanced, dynamic mixes.
  • Major refers to a scale or chord that has a bright, happy, and stable sound. The major scale follows the pattern: whole – whole – half – whole – whole – whole – half. For example, the C major scale includes the notes: C, D, E, F, G, A, B. A major chord (like C major = C–E–G) is built from the root, a major third, and a perfect fifth. Major keys are widely used in pop, classical, and folk music.
  • Masking is a phenomenon where one sound hides another because they share similar frequencies playing at the same time. This can make certain elements (like bass or vocals) hard to hear or distinguish in a mix. It often occurs between the kick and bass, or vocals and harmonic instruments. You can fix masking with tools like EQ, panning, sidechain compression, or spectral processing.
  • A melody is a sequence of single notes played one after another, arranged with rhythm and musical sense to form a recognizable line. It’s often the main or most memorable part of a song — the part people hum or sing. A strong melody blends pitch, rhythm, contour, and often repetition or variation. It can be carried by vocals, instruments, or synths, and usually follows a scale or key. In composition, the melody brings life and emotion to the music.
  • A microphone is a transducer that converts sound waves into an electrical signal. It’s used to record vocals, instruments, ambient sounds, or effects. There are several types of microphones based on their technology (Dynamic, Condenser, Ribbon). Microphones also have different polar patterns (cardioid, omnidirectional, bidirectional…) that determine how they capture sound directionally.
  • Microtonal music involves the use of pitches between the standard 12 semitones of the Western scale. It includes intervals smaller than a semitone, known as micro-intervals. Microtonality is found in many world music traditions(Arabic, Indian, Turkish…) and in some forms of experimental or contemporary music. It allows for the exploration of new, expressive, and unusual tonal colors. In music production, microtonal music can be created using compatible synths (MPE, Scala, etc.) or custom tuning systems.
  • Mid-Side (or M/S) processing is a mixing and mastering technique that separates a stereo signal into two components (the Mid and the Side). This allows you to process the center and sides independently, giving you control to widen the stereo image, clean up the mix, or make surgical adjustments without affecting the whole signal. Mid: the center—what both left and right channels share (often vocals, bass, kick…) Side: the differences between the left and right channels (stereo effects, ambient sounds, wide instruments)
  • MIDI does not contain any audio data. It is a communication protocol that represents musical performance information, functioning similarly to a digital score readable by computers, synthesizers, and other MIDI-compatible devices. Rather than encoding sound, it transmits data such as note on/off events, pitch, velocity, modulation, control changes, and more. One of its key advantages over recorded audio is its non-destructive and highly editable nature, allowing for precise manipulation of musical parameters after performance.
  • Minor refers to a scale or chord that has a darker, more emotional or melancholic sound compared to major. The natural minor scale follows the pattern: whole – half – whole – whole – half – whole – whole. For example, the A minor scale includes the notes: A, B, C, D, E, F, G. A minor chord (like A minor = A–C–E) consists of the root, a minor third, and a perfect fifth. There are also harmonic and melodic minor variations with specific alterations.
  • Mixing is the stage of music production where all the tracks (vocals, instruments, effects, etc.) are balanced, processed, and blended to create a coherent and polished sound. This involves using tools like EQ, compression, panning, reverb, delay, volume adjustments, and sometimes automation. A good mix ensures every element has its place in the sonic space and enhances the emotional impact of the track.
  • Modes are variations of scales derived from the major scale (or others), each with its own distinct mood and color. There are 7 main modes based on the major scale: Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian And Locrian. Modes are widely used in classical music, jazz, funk, rock, and world music to expand harmonic possibilities and create unique melodic flavors.
  • A modular synthesizer is a sound synthesis system made of independent modules (oscillators, filters, envelopes, LFOs, sequencers, etc.) that are connected using patch cables. There’s no fixed signal path: the user creates their own signal flow each time they patch. Modular synths are widely used for sound experimentation, advanced synthesis, and live performances, offering total sonic freedom—but also requiring a solid understanding of signals (audio, CV, gate, etc.). The most common format is Eurorack.
  • Modulation is the act of changing key during a piece of music. It’s used to create contrast, tension, drama, or emotional lift. Modulation can be abrupt (direct modulation), smooth (using pivot chords or melodic shifts), or even temporary (using a secondary or borrowed key). Widely used in classical music, it also appears in pop, soul, jazz, and film scores. A common example is a key change up a semitone in the final chorus for added intensity.
  • The modwheel (short for modulation wheel) is a physical controller found on most MIDI keyboards or synthesizers, usually located to the left of the keys. By default, it controls modulation — such as vibrato, tremolo, a filter, or any other assigned parameter. It allows for adding expression and real-time movement while playing, without needing to use a mouse or software knob. On modern synths, the modwheel can be mapped to virtually any parameter.
  • Mono (short for monophonic) refers to an audio signal played through a single channel, as opposed to stereo, which uses two (left and right). In mono, the sound is identical in both speakers or ears. Mixing in mono is essential for checking phase coherence, ensuring clarity and balance, and verifying that the track still sounds good on limited playback systems like phones, radios, or Bluetooth speakers.
  • Monophony refers to a musical texture where only one note is played at a time, with no accompanying chords or harmonies. It can involve a single voice, instrument, or synthesizer performing a single melodic line. In sound synthesis, a monophonic synth can only play one note at a time — ideal for basslines, expressive leads, or sounds using portamento/glide. Monophony contrasts with polyphony, where multiple notes can be played simultaneously.
  • A multi-sampled instrument is a virtual instrument or preset built from multiple recorded samples captured at different pitches, dynamics, or articulations. Unlike a single sample stretched across the keyboard, each note (or group of notes) has its own recording, resulting in more realism and expressiveness. This approach is commonly used in professional sound libraries for pianos, drums, strings, brass, and other acoustic instruments.
  • Multiband refers to audio processing that splits the signal into separate frequency ranges (bands), allowing each one to be processed independently. For example, a multiband compressor can compress the lows, mids, and highs separately. This provides greater control and precision, especially in mixing, mastering, and sound design. It’s useful for applying targeted adjustments without affecting the whole frequency spectrum.
  • Normalization is the process of automatically adjusting the gain of an audio file so that its peak level reaches a target value, without altering its internal dynamics. It helps unify loudness between files or maximize level without exceeding 0 dBFS (digital ceiling).
  • NY Compression (New York Compression), also known as parallel compression, is a technique where a dry (uncompressed) signal is blended with a heavily compressed version of the same signal. This approach enhances the punch, density, and presence of a sound—commonly drums, vocals, or the mix bus—while retaining its natural dynamics. Widely used in New York studios, it’s now a staple of modern, powerful mixing.
  • An oscillator is the core sound generator of a synthesizer. It produces a repeating audio signal, typically in the form of waveforms like sine, square, triangle, or sawtooth. Each waveform has its own timbre, rich or limited in harmonics. The oscillator defines the pitch of the sound, which can then be shaped by filters, envelopes, LFOs, and more. Multiple oscillators can be combined to create richer, thicker sounds, and slightly detuned for phasing or detune effects.
  • An ostinato is a repeating rhythmic, melodic, or harmonic pattern that continues throughout a piece or a musical section. It often serves as a foundation over which other elements are layered or developed. Widely used in classical music, jazz, rock, and electronic genres, the ostinato creates a hypnotic, driving, or dramatic effect depending on the context.
  • Overdub is a recording technique where you add a new audio (or MIDI) track on top of an existing take, while listening to it in real time. Widely used in studio production, this method allows for layering additional vocals, harmonies, doubles, solos, sound effects, and more—without re-recording the full performance. Overdubbing is a core part of multitrack recording, whether in music, film, or podcast production.
  • Oversampling is a technique where an audio signal is processed at a higher sample rate than the project’s base rate—often 2x, 4x, 8x, or more. This helps reduce digital artifacts like aliasing, especially when using distortion, saturation, or fast modulation effects. After processing, the signal is downsampled back to the original rate. Oversampling improves audio quality, but it can increase CPU load.
  • Pan (short for panning) is a mixing control that allows you to position a sound within the stereo field, from left to right. By default, sounds are centered, but adjusting the pan makes them lean to one side, helping create a sense of space, separation, and clarity in a mix. It’s used on vocals, instruments, drums, and more to organize the stereo image and avoid frequency masking.
  • Pan (short for panning) is a mixing control that allows you to position a sound within the stereo field, from left to right. By default, sounds are centered, but adjusting the pan makes them lean to one side, helping create a sense of space, separation, and clarity in a mix. It’s used on vocals, instruments, drums, and more to organize the stereo image and avoid frequency masking.
  • A pattern is a repeating rhythmic, melodic, or harmonic sequence used in a musical piece or project. In music production, a pattern can include MIDI notes, audio events, automation, or drum hits, and serves as a building block for creating songs in a loop-based or block-oriented workflow (common in DAWs like FL Studio, Ableton Live, etc.). Patterns help with structured composition, variation, and arrangement.
  • Phase refers to the timing position of a sound wave, relative to another. Two signals of the same frequency can be in phase (peaks and troughs aligned) or out of phase (waveforms misaligned). When similar sounds are out of phase, they may cancel each other partially or completely, causing issues like volume loss, frequency dips, or mono incompatibility. Managing phase is crucial in situations involving multiple microphones, layered sounds, or stereo mixing.
  • Physical modeling is a sound synthesis method that simulates the real-world physical behavior of an instrument(strings, wood, metal, air, etc.) using mathematical equations. Instead of relying on samples or traditional waveforms, it recreates sound by modeling physical interactions—like string vibration, tube resonance, or air pressure. This technique allows for highly expressive, dynamic, and realistic sounds, while being lightweight in terms of memory. It’s used in advanced synths like SWAM, AAS Chromaphone, or the Arturia Physical Modeling Suite.
  • Pitch refers to the perceived frequency of a sound—whether it sounds high or low. The higher the frequency (measured in hertz), the higher the pitch; the lower the frequency, the lower the sound. For example, A at 440 Hz is a common tuning reference. In music, pitch is essential for playing notes, tuning instruments, composing melodies, and building harmonies. In production, pitch can be manipulated (transposing, pitch-shifting) to create effects or adapt recordings.
  • The pitchwheel (or pitch bend wheel) is a physical controller found next to the keyboard on most synthesizers and MIDI controllers. It allows for continuous pitch variation up or down, creating a gliding or bending effect, similar to what you’d hear on a guitar or wind instrument. It’s commonly used to add expressiveness to leads, basslines, or solo instrument parts.
  • Plate reverb is an analog reverb type created by sending an audio signal into a large suspended metal plate (typically steel), which vibrates and is captured by transducers. This produces a dense, smooth, and bright reverberation. Introduced in the 1950s, plate reverb became a studio staple, especially for vocals, drums, and solo instruments. It offers a rich and warm tone without the realism of a physical space, making it perfect for adding presence and body without cluttering the mix.
  • A plugin is a software-based audio processor or instrument that integrates into a digital audio workstation (DAW) to extend its capabilities. Allows for the emulation of hardware synthesizers, samplers, effects processors (such as EQs, compressors, reverbs), and more—all within a software environment. Plugins process either MIDI input (in the case of virtual instruments) or audio input (for effects), and they can be automated, modulated, and synchronized within a DAW. Their modularity and flexibility have made them an essential component of modern music production workflows.
  • Polymeter is a rhythmic technique where multiple time signatures (like 3/4 and 4/4) are played simultaneously, each maintaining its own meter and cycle. Unlike polyrhythm (which overlaps note groupings within the same measure), polymeter keeps separate bar lengths, causing the patterns to phase in and out over time. This creates a sense of shifting rhythm and evolving groove, commonly found in modern jazz, contemporary classical music, African traditional music, and progressive metal.
  • Polyphony refers to the ability to play multiple notes at the same time, whether in composition or on an instrument. In sound synthesis, a polyphonic synthesizer can produce several voices simultaneously, unlike a monophonic synth, which plays only one note at a time. This allows for chords, melody with accompaniment, or rich layered textures. The number of available voices (e.g., 4, 8, 16, 64) defines a synthesizer’s or virtual instrument’s maximum polyphony.
  • Polyrhythm is a rhythmic technique where two or more different rhythms are played simultaneously, each with its own grouping of beats. For example, a 3 against 2 (3:2) polyrhythm means three evenly spaced notes played in the time of two. Each rhythm maintains its own pulse, creating a complex and often hypnotic texture. Polyrhythms are widely used in African music, jazz, contemporary classical, and some forms of experimental electronic music.
  • Portamento is a musical effect or technique where the pitch glides smoothly from one note to another without a sudden jump. In synthesizers and virtual instruments, portamento can be enabled to automatically create glides between legato-played notes. It’s widely used in lead sounds, basses, and expressive instruments, especially in electronic music, funk, and R&B. Read More
  • A preset is a predefined configuration of parameters within a plugin. It serves as a snapshot of settings—such as oscillator types, filter cutoffs, envelope shapes, effect chains, and modulation routings—that produce a specific sound or behavior. Presets allow users to quickly load complex sounds without manually adjusting each control, making them essential for efficient workflow and sound design exploration. While presets provide immediate access to usable sounds, they can also serve as starting points for custom sound creation.
  • Quantize is a music production function that automatically adjusts the timing of MIDI or audio notes to align them precisely with a rhythmic grid (beats, 16th notes, triplets, etc.). It’s commonly used to correct timing imperfections or to tighten up a performance for a more mechanical feel. Many DAWs also offer percentage-based quantization, allowing some degree of natural groove to remain.
  • In mixing, a reference track is a professionally mixed and mastered song used to compare and guide your own mix. It helps assess aspects like frequency balance, dynamics, stereo width, loudness, and more. Using a good reference helps maintain objectivity and avoid ear fatigue during long sessions. It’s best to choose references in the same genre as your track and match the playback volume for fair comparison.
  • A remix is an alternative version of an existing track, where the producer modifies, rearranges, or replaces elements such as rhythm, harmony, vocals, or structure to give it a new stylistic direction. A remix can be more danceable, experimental, stripped-down, or tailored to a different audience or genre (e.g., turning a pop ballad into a club techno track). It’s common in electronic music, hip-hop, pop, and remix contests. A remix usually keeps key parts of the original (like the vocal or main hook), while offering a fresh artistic perspective.
  • Reverb (short for reverberation) is an audio effect that simulates the natural reflections of sound within a space (room, hall, cathedral, etc.). When a sound is produced, it bounces off surrounding surfaces and returns to our ears as scattered, decaying echoes, creating a sense of space, depth, and atmosphere. In music production, reverb is used to place a sound in a virtual environment, glue elements together, or add aesthetic effects. Common types include hall, room, plate, spring, and convolution reverb.
  • Rhythm is one of the fundamental elements of music. It refers to the organization of sounds over time, through sequences of durations, silences, accents, and repetitions. Rhythm shapes the tempo, meter, beats, and percussive patterns. It can be regular (as in pop or electronic music) or complex and free (as in jazz, contemporary, or traditional music). Rhythm provides a track with energy, direction, and cohesion.
  • The rhythm signature (time signature) tells you how time is organized in a piece of music. It’s written as a fraction, such as 4/4, 3/4, 6/8, etc. The top number shows how many beats per bar, The bottom number tells which note value gets one beat. Some genres use complex or odd signatures like 7/8 or 5/4, often found in jazz, prog, and world music.
  • The root is the base note of a chord or a scale. It defines the name and key of a piece. For example, in a C major chord, C is the root. In the A minor scale, A is the root. It’s the central reference point around which other notes are built, and it plays a key role in shaping chords, melodies, and the overall harmony of a track.
  • Rough balance is the initial stage of mixing, where the relative volumes of the tracks are adjusted without applying effects or processing. The goal is to create a first, coherent version where every element is audible and sits in the mix. This starting point helps define the priorities of the mix before adding EQ, compression, or spatial effects.
  • Round-robin is a sampling technique used to avoid repeating the exact same sample every time a note is triggered. Multiple variations of the same sound (like a snare hit) are recorded and played in rotation, adding realism and variation—especially for drums and acoustic instruments. This helps avoid the “machine gun effect” and gives a more natural, human feel to the performance.
  • A sample is a short audio clip taken from any sound source: a song, voice, sound effect, vinyl record, movie, instrument, etc. This audio fragment can then be reused, sliced, modified, and integrated into a new musical composition using a sampler or audio software. Samples can be rhythmic (drum hits, loops), melodic, vocal, or ambient. They are widely used in electronic music, hip-hop, pop, trap, and cinematic production.
  • Sample rate is the number of times per second an audio signal is measured (sampled) during analog-to-digital conversion. It’s expressed in hertz (Hz) like 44.1, 48, 96. The higher the sample rate, the more accurately high frequencies can be captured, according to the Nyquist theorem. However, it also increases file size and CPU usage. In music production, it’s important to balance quality and performance when choosing a sample rate.
  • A sampler is an instrument or software that allows you to play, manipulate, and transform recorded sounds, known as samples. These can include vocals, instruments, sound effects, loops, drums, and more. A sampler lets you trigger these sounds using a keyboard, pad, or MIDI sequence, with advanced editing options like slicing, pitch shifting, filtering, envelopes, modulation, time-stretching, and more. It’s a key tool in beatmaking, hip-hop, electronic music, sound design, and experimental composition.
  • Sampling is a music production technique that involves recording, cutting, and reusing a snippet of sound from another song, a movie, a vinyl record, or any audio source. The sample can then be manipulated, transformed, or integrated into a new composition, often using a sampler. Sampling is foundational in hip-hop, electronic music, lo-fi, and beatmaking, and ranges from simple loops to complex audio collages. It can be creative, nostalgic, or subversive, depending on how it’s used.
  • A scale is a sequence of notes arranged in a specific order, often used as the foundation for melodies, chords, and harmonies. The most well-known is the major scale, which sounds bright and uplifting, while the minor scale has a darker, more emotional feel. There are also pentatonic, blues, and modal scales (like Dorian, Lydian, etc.), each with its own unique color. Knowing scales is essential for improvising, composing, and understanding musical structure.
  • Sibilance refers to the excessive presence of “s” and “sh” sounds (sibilant sounds) that become harsh or piercing, especially in recorded vocals. It typically occurs in the high frequency range (around 5 kHz to 10 kHz) and can be unpleasant to the ear, particularly when vocals are compressed or poorly recorded. To fix it, a de-esser is used—a dynamic processor that automatically reduces sibilance without affecting the rest of the vocal signal.
  • Sidechain is an audio production technique where the signal from one track controls an effect applied to another — most commonly compression. For example, in electronic music or hip-hop, the kick drum can trigger a compressor on the bass or pads, creating a pumping rhythmic effect. This helps clear space in the mix, emphasize the kick, and add movement to the track. Sidechaining can also be used creatively to modulate a filter, reverb, volume, and more.
  • Slices are segments cut from an audio sample, often taken from a longer loop or recording (like a musical phrase, vocal line, or drum break). Slicing is used to rearrange, recompose, or creatively manipulate the original sample. This technique is widely used in samplers and DAWs, using auto-slice features (based on transients, tempo, or grid). Slices let producers trigger parts of a sample as individual notes using a keyboard or pads — common in hip-hop, lo-fi, house, drum’n’bass, and more.
  • Sound design is the art of creating, shaping, or manipulating sounds for artistic, musical, cinematic, interactive, or experimental purposes. It can involve synthesizing sounds, recording foley or field audio, editing samples, or applying audio effects to craft a unique result. Sound design is essential in electronic music, video games, film, advertising, podcasts, and sound installations. It can be abstract, realistic, or stylized, and plays a key role in establishing the identity and atmosphere of any audio project.
  • Sidechain is an audio production technique where the signal from one track controls an effect applied to another — most commonly compression. For example, in electronic music or hip-hop, the kick drum can trigger a compressor on the bass or pads, creating a pumping rhythmic effect. This helps clear space in the mix, emphasize the kick, and add movement to the track. Sidechaining can also be used creatively to modulate a filter, reverb, volume, and more.
  • Spring reverb is an analog type of reverb that uses one or more metal springs to simulate sound reflections. The audio signal is sent through the springs, which vibrate and produce a distinctive mechanical reverb with a metallic, vintage, slightly gritty tone. It’s widely used in guitar amps, organs, and dub/reggae effects, adding a warm, retro character, often with a natural wobble or shimmer. It’s great for raw, lo-fi, or expressive sounds.
  • Stereo refers to audio playback using two separate channels, left (L) and right (R), which creates a sense of width and spatial depth. Unlike mono (a single centered signal), stereo allows sounds to be placed across the horizontal sound field, offering more realism, clarity, and dimensionality. In music production, stereo is used for panning instruments, creating wide effects, or applying mid/side processing. Good stereo management enhances space and separationwithout compromising mono compatibility.
  • Swing is a deliberate rhythmic shift that creates a loose, groovy, and danceable feel. Instead of playing notes evenly spaced, swing slightly delays certain ones (typically the even 16th notes), producing a sense of bounce or lilt. Widely used in jazz, hip-hop, house, and more, swing helps humanize sequences and make them feel more alive. Most DAWs allow you to adjust the swing percentage to fine-tune this effect.
  • Syncopation is a rhythmic effect where accents are placed off the regular beats, emphasizing weak beats or offbeatsinstead of the usual strong ones (like beats 1 and 3 in 4/4 time). This creates a sense of displacement, rhythmic tension, and a unique groove. Syncopation is widely used in jazz, funk, Latin music, as well as hip-hop, afrobeat, and some forms of electronic music. It adds life, motion, and swing to rhythmic or melodic lines.
  • Sound synthesis is the art of creating artificial sounds using synthesizers—hardware or software. Instead of recording real-world sounds, synthesis generates sound from scratch using waveforms, filters, envelopes, and modulation. There are several types of synthesis, each with its own approach to building sound: Subtractive, Additive, FM (Frequency Modulation), Granular, Wavetable, Physical modeling, Vector, and more.
  • Tempo is the speed at which a piece of music is played, measured in beats per minute (BPM). For example, a tempo of 120 BPM means there are 120 beats per minute. Tempo greatly affects the feel, energy, and style of a track. In DAWs, tempo can be fixed or automated, and it can be synced with plugins, loops, or external hardware.
  • Threshold is a key parameter in dynamics processors such as compressors, limiters, de-essers, and gates. It sets the level (in dB) at which the effect starts to apply. In a compressor, when the signal exceeds the threshold, it is reduced according to the chosen ratio. In a gate, signals below the threshold are muted or reduced. In a de-esser, the threshold determines when sibilance is reduced. Setting the threshold correctly is crucial to control volume, dynamics, and clarity without distorting the original sound. Read More
  • Tone is what allows us to distinguish between two sounds that have the same pitch and loudness. It’s the sound color of an instrument or voice, shaped by waveform, harmonics, dynamics, attack, resonance, and more. For example, a violin and a flute can play the same note at the same volume, yet sound completely different. Timbre is central to the sonic identity of an instrument, plugin, or mix, and plays a key role in sound design and synthesis.
  • The tonic is the main note of a scale and the tonal center around which a piece of music is organized. It serves as the natural starting and ending point of melodies and chord progressions. For example, in C major, the tonic is C. It gives the key its name and corresponds to the I degree in music theory. In a song, the tonic provides a sense of rest, stability, and resolution, contrasting with tension chords like the dominant (V).
  • A transient is the short, sharp initial attack of a sound, typically found at the beginning of a drum hit, snap, piano note, or percussive vocal. It’s the burst of energy that gives the sound its punch, clarity, and rhythmic precision. Transients are crucial for making a sound cut through the mix. They can be enhanced or softened using tools like transient shapers, fast compressors, or through manual editing.
  • A triad is a basic chord made up of three notes: The root (the base note of the chord) The third (major or minor, which defines the chord’s color) The perfect fifth (which adds stability) There are four main types of triads: Major: root + major third + perfect fifth (e.g., C–E–G) Minor: root + minor third + perfect fifth (e.g., A–C–E) Diminished: root + minor third + diminished fifth Augmented: root + major third + augmented fifth Triads are the building blocks of harmony in Western music. They are used to form chord progressions, support melodies, and(...) Read More
  • Tuning refers to the adjustment of pitch — that is, the frequency of a sound.  In modern music, standard reference is A at 440 Hz, but sounds can be intentionally  detuned to create tension, warmth, or instability. Tuning is also used in sound design  to match oscillators or samples, ensuring harmonic consistency.
  • A vocoder is an audio effect that transforms a voice (or other audio signal) into a robotic or synthetic-sounding output by applying its vocal characteristics (frequencies, articulation) to a carrier signal (usually a synthesizer). The vocoder analyzes the spectral content of the modulator (voice) and imprints it onto the carrier, producing a harmonic and mechanical effect. Widely used in electro, funk, pop, hip-hop, and sci-fi soundtracks, vocoders are also great tools for experimental sound design.
  • A VU meter (Volume Unit meter) is a visual tool that shows the average loudness of an audio signal, closely matching the way humans perceive volume. Unlike peak meters, which react instantly to signal spikes, the VU meter responds more slowly and reflects the overall power of the sound (roughly RMS level). It’s especially useful for: Balancing mix levels Keeping consistent vocal or broadcast levels Preserving healthy dynamics A common reference point is to aim for 0 VU, which typically aligns with -18 dBFS in digital audio systems. Read More
  • In Ableton Live, the Warp function allows you to change the timing of an audio file without altering its pitch, or adjust the pitch without changing its speed. It’s a powerful time-stretching tool that lets you sync samples, loops, vocals, or recordings to the project tempo, even if they were originally at a different BPM. Warp Markers are used to align specific points in the audio with the beat grid. Ableton offers multiple Warp modes (Beats, Tones, Texture, Re-Pitch, Complex, Complex Pro), optimized for different types of material (percussive, melodic, vocals…). Read More
  • A waveform is the visual or mathematical representation of an audio signal over time. It shows how the amplitude of the sound changes, and reflects timbre characteristics: Sine wave = pure tone, no harmonics Square wave = rich in odd harmonics Sawtooth wave = bright and rich in harmonics Triangle wave = softer than square, richer than sine In music production, waveforms help visualize audio, identify transients, edit with precision, and serve as the foundation for sound generation in synthesizers. Read More
  • A wavetable is a collection of waveforms stored in a digital table, which can be scanned or modulated in real time to produce evolving, textured sounds. Unlike traditional subtractive synthesis (which uses a single static waveform), wavetable synthesis lets you morph between different waveforms (via LFO, envelope, etc.), resulting in dynamic and expressive timbres. It’s widely used in modern synths like Serum, Vital, Massive, and Ableton Wavetable, and is capable of creating anything from sharp digital tones to rich, complex textures. Read More
  • Wet refers to the processed signal in an audio effect (such as reverb, delay, chorus, etc.). Opposite of dry (the original signal), the wet signal contains only the effect. The dry/wet control allows you to balance between natural and processed sound. The wetter the signal, the more noticeable the effect—ideal for adding space, depth, or texture.
