A first order (single pole) all-pass filter for applying frequency-conscious phase shifting, whilst maintaining a flat magnitude response. The phase angle, and the frequency, at which the phase angle is to apply, is both adjustable.
Defaults to yes. Optimized IIR filter for improved low frequency performance. This is optional to maintain backwards compatibility with existing designs.
Frequency: For adjusting the frequency at which the phase angle is to apply.
Phase: For adjusting the phase angle by which the signal is to be shifted at the frequency set by the Frequency control.
