------- Comment #2 from Stefan Kost (gstreamer, gtkdoc dev)  2007-02-10 20:42 UTC -------
"... When the Compressor is set for Hard knee, the compression ratio applies
only to signals above the threshold level. If the Compressor is set for Soft
knee, the compression ratio gradually increases from 1:1 to the currently
selected ratio over a range of approximately 5 dB, so that the transition from
uncompressed to compressed is more gradual. The difference between Hard Knee
and Soft Knee is more obvious at high compression ratios. Once the input signal
crosses the Threshold, the unit will compress the signal at the full ratio
level. ..."
