Hold (0 to 5000ms)
Sets the time the applied compression will affect the signal after exceeding the thresh-
old. Short hold times are useful for "DJ-style" ducking, while longer hold times are
required for music ducking, e.g. when working on a documentary film.
Release (10 to 1000ms or Auto mode)
Sets the amount of time it takes for the gain to return to its original level when the
signal drops below the threshold level. If the Auto button is activated, Compressor will
automatically find an optimal release setting that varies depending on the audio material.
Analysis (0 to 100) (Pure Peak to Pure RMS)
Determines whether the input signal is analyzed according to peak or RMS values (or
a mixture of both). A value of 0 is pure peak and 100 pure RMS. RMS mode operates
using the average power of the audio signal as a basis, whereas Peak mode operates
more on peak levels. As a general guideline, RMS mode works better on material with
few transients such as vocals, and Peak mode works better for percussive material with
a lot of transient peaks.
Live button
When this button is activated, the "look ahead" feature of Compressor is disengaged.
Look ahead produces more accurate processing, but adds a certain amount of latency
as a trade-off. When Live mode is activated, there is no latency, which might be better
for "live" processing.
