Threshold

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.
