Haas effect
« Back to Glossary Index
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.
