Note 30. The passband and stopband frequencies scale with fs (system sampling rate).
For example, PB=0.454*fs (@−0.05dB). Each response refers to that of 1kHz.
Note 31. The calculated delay time caused by digital filtering. This time is from setting the 16-bit data of both channels
from the input register to the output of analog signal. HPF=LPF=FIL3=EQ=5-BiQuads=ALC=OFF.
