Release (Compressor)
Definition
The time it takes for a compressor to return to unity gain after the signal falls below the threshold. A fast release can cause pumping; a slow release provides smoother, more transparent control.
In Simple Terms
How fast a compressor lets go after the loud moment passes. Too fast and you hear pumping—the volume breathing unnaturally. Too slow and the compressor never resets before the next hit. Finding the right release makes compression invisible.
In Practice
A slow release on a vocal compressor prevents audible pumping between phrases, maintaining consistent compression even as the singer takes breaths between lines.
