AllPass¶

Inputs¶

• signal (real) - the input signal

Outputs¶

• signal (real) - the filtered signal

Parameters¶

• bandwidth (real ∈ (0, ∞), default = 500) :

  the bandwidth of the filter [Hz] (used only for 2nd-order filters)

• cutoffFrequency (real ∈ (0, ∞), default = 1500) :

  the cutoff frequency for the filter [Hz]

• order (integer ∈ {1, 2}, default = 1) :

  the order of the filter

• sampleRate (real ∈ (0, ∞), default = 44100) :

  the sampling rate of the audio signal [Hz]

Description¶

This algorithm implements a IIR all-pass filter of order 1 or 2. Because of its dependence on IIR, IIR’s requirements are inherited.
