@table @option
@item level_in
Set input level before filtering.
Default is 1. Allowed range is from 0.015625 to 64.
@item range
Set the level of gain reduction when the signal is below the threshold.
Default is 0.06125. Allowed range is from 0 to 1.
@item threshold
If a signal rises above this level the gain reduction is released.
Default is 0.125. Allowed range is from 0 to 1.
@item ratio
Set a ratio about which the signal is reduced.
Default is 2. Allowed range is from 1 to 9000.
@item attack
Amount of milliseconds the signal has to rise above the threshold before gain
reduction stops.
Default is 20 milliseconds. Allowed range is from 0.01 to 9000.
@item release
Amount of milliseconds the signal has to fall below the threshold before the
reduction is increased again.
reduction is increased again. Default is 250 milliseconds.
Allowed range is from 0.01 to 9000.
@item makeup
Set amount of amplification of signal after processing.
Default is 1. Allowed range is from 1 to 64.
@item knee
Curve the sharp knee around the threshold to enter gain reduction more softly.
Default is 2.828427125. Allowed range is from 1 to 8.
@item detection
Choose if exact signal should be taken for detection or an RMS like one.
Default is peak. Can be peak or rms.
@item link
Choose if the average level between all channels or the louder channel affects
the reduction.
Default is average. Can be average or maximum.
