THRESHOLD
SOFT_KNEE
Field
This sets the threshold level of the audio compressor. Audio signals above
the threshold will be compressed.
If set, the audio compressor will automatically apply higher compression ratios
to audio signals higher than the threshold level. As the audio signal
approaches levels higher than the threshold, SOFT_KNEE will increase the
compression RATIO. The highest compression that the SOFT_KNEE
algorithm will apply is the compression that is set by RATIO.
