OUTPUT / Compressor
A Compressor is used to control and reduce the dynamic range of the signal.
RMS/Peak – Compression is either triggered by RMS (short average) or Peak
(instant) signal level.
Hard/Soft Knee – With a hard knee, compression begins to take effect only when
the threshold is reached. With a soft knee, the compression begins to take effect
earlier but in a more gradual way.
Attack – Adjust the time it takes for compression to take effect once the signal
has reached the threshold. Set a longer time to allow transients through and
compress only the body of the sound, set a shorter time to flatten the signal and
tame peaks.
Release – Adjust the time that it takes for the compressor to stop compressing
after signal has fallen below the threshold.
