 3 x 1400-tap monaural 4CH filter
 4 x 1050-tap stereo 3CH filter
o Adaptive filters derate to 2100 and 1000 total filter taps at 10kHz
and 20kHz bandwidths, respectively

 Algorithms:
o Time-domain, continuous adjustment, Normalized Least Mean
Square (NLMS) for all 1CH, 2CH, 3CH, and 4CH adaptive filters
o Automatic “crash detection” and clearing for all adaptive filters
o Fourth-order Butterworth IIR implementation for 200Hz highpass
filter
o Time-domain, peak-sensitive, envelope tracking compressor with
“lookahead” for AGC
