# Low-pass filter audio AudioLowPassFilter

AudioLowPassFilter passes the low frequency of the audio source and filters out signals with frequencies higher than the cutoff frequency frequency.

Properties Features
frequency Low-pass cutoff frequency, in Hertz (range from 10 to 22000, default 350).
Q Low-pass filter quality value (range from 0.0001 to 100, default 1). Control at the cut-off frequency, the peak value reached by the amplification of the original signal due to resonance. The greater the Q value, the greater the peak value, that is, the greater the impact on the original signal near the cutoff frequency. But the larger the Q value, the narrower the roll-off range and the better the filtering effect of the filter. For more information, please refer to here.
