LowPass

streaming mode | Filters category

Inputs

  • signal (real) - the input audio signal

Outputs

  • signal (real) - the filtered signal

Parameters

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

    the cutoff frequency for the filter [Hz]

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

    the sampling rate of the audio signal [Hz]

Description

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