TABLE 81. SOFTCLIP1 (0xB0h)
SOFT_KNEE
TRESHOLD
Field
92
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.
