### Scenarios where Phase Response is (non-)problematic

One audio example: The human ear is quite insensitive to monaural phase but quite very sensitive to interaural phase. Let's make a stereo signal by simply duplicating a mono signal. If you apply a (...

### Output Precision for Filter

The log2 computation is really a consideration for the size of the (extended precision) accumulator for a fixed point FIR filter design: The sum of the absolute value of the coefficients is the ...
