DCRemoval¶
standard mode | Filters category
Inputs¶
signal
(vector_real) - the input audio signal
Outputs¶
signal
(vector_real) - the filtered signal, with the DC component removed
Parameters¶
cutoffFrequency
(real ∈ (0, ∞), default = 40) :the cutoff frequency for the filter [Hz]
sampleRate
(real ∈ (0, ∞), default = 44100) :the sampling rate of the audio signal [Hz]
Description¶
This algorithm removes the DC offset from a signal using a 1st order IIR highpass filter. Because of its dependence on IIR, IIR’s requirements are inherited.
