Stereo and Mono Sidechain Compressors for Tracktion

Hard Knee and Soft Knee Compression

Snare Track Compression

The terms hard and soft do not refer to sound, but rather the way that the compressor reacts to incoming signals. The difference is somewhat subtle to hear, but is more apparent at higher compression ratios. A hard knee setting is well suited to lower ratios. When using higher compression ratios, you may ﬁnd it a little better- sounding to draw in a smoother knee curve.

A hard knee curve is represented as a straight line that connects a point on the threshold to the end point or maximum output on the graph.

The graph below could be used on a snare track to drastically lower the volume of a few snare hits by an over-excited drummer, while leaving most of the snare track unaffected.

A soft knee curve has a smoother curve that connects the two points. This creates a more gradual transition between non-compressed and compressed signals.
