Manual: Audio Low Pass Filter - Unity

https://docs.unity3d.com/Manual/class-AudioLowPassFilter.html

The Lowpass Resonance Q (short for Lowpass Resonance Quality Factor) determines how much the filter’s self-resonance is dampened. Higher lowpass resonance quality indicates a lower rate of energy loss, that is the oscillations die out more slowly. The Audio Low Pass Filter has a Rolloff curve associated with it, making it possible to set Cutoff Frequency over distance between the …

The Audio Low Pass Filter passes low frequencies of an AudioSource or all sounds reaching an AudioListener, while removing frequencies higher than the Cutoff Frequency. See Also: Audio Low Pass Filter information. Properties. customCutoffCurve: Returns or sets the current custom frequency cutoff curve.

Cancel. Copy to Clipboard. You gave enough information for the Signal Processing Toolbox (with a bit of help from me) to be able to design your filter: Fs = 8000; % Sampling Frequency (Hz) Fn = Fs/2; % Nyquist Frequency. Fco = 20; % Passband (Cutoff) Frequency. Fsb = 30; % Stopband Frequency.

Theoretically, the ideal (i.e., perfect) low-pass filter is the sinc filter. The sinc function (normalized, hence the \(\pi\)’s, as is customary in signal processing), is defined as \[\mathrm{sinc}(x)=\frac{\sin(\pi x)}{\pi x}.\] The sinc filter is a scaled version of …

Here’s my explanation using what you see in the link. The basic formula for a discrete Infinite Impulse Response (IIR) low-pass filter (LPF) being: y (i)= β∗x (i)+ (1-β)∗y (i-1) y (i) is the present output of the LPF whereas y (i-1) is the previous output and x (i) is the present input.
