The allpass filter has adjustable frequency and ‘Q’ (or
Bandwidth) controls. These affect the frequency at which the
phase effectively flips 180°, and the ‘speed’ at which this
transition occurs.

The graph shows an allpass filter centred at 1kHz, with various
‘Q’ settings – the higher the ‘Q’ the faster the transition.

The phase filter has adjustable frequency, and phase shift
controls. This introduces a phase shift that gradually changes
from 180° above the centre frequency to the specificed value
at the centre frequency, and tending towards 0° below the
centre frequency.

This graph shows the phase shift relative to the input (ignoring
processing delays), in 10° steps – the filter will actually provide
higher resolution than this, operating in 2° steps.The filter is
centred at 1kHz in this example.
