AllPass

standard mode | Filters category

Inputs

  • signal (vector_real) - the input signal

Outputs

  • signal (vector_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.
