LowPass¶

standard mode | Filters category

Inputs¶

signal (vector_real) - the input audio signal

Outputs¶

signal (vector_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.
