Graphs showing the three knee types. Note that hard knee has hardly any curve at all, while the knee
becomes noticeably more rounded in soft knee mode.
Hard knee Medium knee Soft knee
Compressive display types
With a signal running through the compressor, a coloured line on the graph
follows the contour of the shaded graph area. The line’s colour changes according
to which of the three signal levels it is at.
• Uncompressed If signal doesn’t reach threshold (point where
gradient changes), the line is green. As the threshold is not exceeded,
the signal is uncompressed.
• Within knee area If signal goes into knee area to point where gradient
changes (more obvious with medium and soft knees), compression starts to
be applied and line colour changes to yellow.
• Full compression If signal reaches the point where gradient changes
(overthreshold), full compression at selected ratio is applied and line colour
changes to red.
Knee type
There are three knee types as follows, which are illustrated in the
following diagram:
• Hard knee Compressor immediately applies gain reduction at selected ratio
once attack time has elapsed.
• Medium knee Intermediate knee type.
• Soft knee Compressor, starting from slightly before threshold, gradually
makes the transition to applying gain reduction at selected ratio.
