Release

The ‘Release’, in terms of audio, is a segment of a sound’s envelope or temporal shape. It is the time it takes for the sound to stop after a note has been released.

Percussive instruments have extremely short releases whereas bowed instruments and wind instruments may have short releases if played in legato, or shorter releases when played in staccato.

Release can also refer to the time it takes for a compressor/expander/plugin to stop affecting the signal after i falls back below the specified threshold. It is usually measured in milliseconds (ms).
