Description

Lowpass cutoff frequency in hz. 10.0 to 22000.0. Default = 5000.0.

Note that setting this value will reset any custom cutoff curve set for this AudioLowPassFilter.

	// Moves the cuttoutFrequency from 10 to 22000 following a Sinus function
	// Attach this to an audio source with a LowPassFilter to listen it working.
