Bits Field Description
3:0 THRESHOLD This sets the threshold level of the audio compressor. Audio signals above the threshold
will be compressed.
THRESHOLD Threshold Level (dB)
0000 -36dB
0001 -30dB
0010 -24dB
0011 -20dB
0100 -18dB
0101 -17dB
0110 -16dB
0111 -15dB
1000 -14dB
1001 -12dB
1010 -10dB
1011 -8dB
1100 -6dB
1101 -4dB
1110 -2.5dB
1111 -1dB
4 SOFT_KNEE 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.
