A compressor lowers the dynamic range of a signal by reducing the level of
high volume signals and applying an overall gain to raise the level up again.
Compression is often used in vocals and music to get even volume levels which
often results in a smoother, fuller sound.
THRESHOLD LEVEL (-60 TO 0 DB)
Signal level that differentiates the Attack and Release modes. In a simple
compressor or gate, the threshold is the level at which the gain begins to
deviate from 1.
RATIO (1:1 TO INF.)
Ratio of input to output levels above the Threshold. This Ratio determines how
much a signal above the Threshold will be boosted or faded as a function of its
level. When changing the Ratio, all points above the Threshold move closer or
further away from the No Gain line.
ATTACK TIME (0 TO 500 MS)
Time, in milliseconds, required for the gain to change from a pre-threshold
level to a post-threshold level.
RELEASE TIME (0 TO 2,000 MS)
Time, in milliseconds, required for the gain to change from a post-threshold
level to a pre-threshold level.
AUTO GAIN COMPENSATE (ON/OFF)
When on, a gain is applied during processing to try to keep the maximum
input and output levels constant. In general, this gain will be equal to the
highest envelope point in the graph.You can still use the Output gain control
to fine tune the overall gain.
For best results, very low frequencies (below 20 Hz) present in a sound
file should be removed before applying the Dynamics functions.This
makes it easier to monitor audible frequencies while compressing.
