The FirstOrderFilter is operated in ‘Phase Filter’ mode that passes all frequencies equally in gain, but changes the
phase relationship between various frequencies. The phase shift varies as a function of frequency.
In the Phase Filter mode, the block receives the following filter specifications from the user for each filter in a
channel:
- Frequency (in Hz), f
- Phase for given frequency (range of 0° –> 180°)
- Bypass mode (if set, the block doesn’t filter the incoming audio buffer)
