Audio Chorus Filter (PRO only)

The Audio Chorus Filter takes an Audio Clip and processes it creating a chorus effect.

The chorus effect modulates the original sound by a sinusoid low frequency oscillator (LFO). The output sounds like there are multiple sources emitting the same sound with slight variations - resembling a choir.

Properties

Dry Mix	Volume of original signal to pass to output. 0.0 to 1.0. Default = 0.5.
Wet Mix 1	Volume of 1st chorus tap. 0.0 to 1.0. Default = 0.5.
Wet Mix 2	Volume of 2nd chorus tap. This tap is 90 degrees out of phase of the first tap. 0.0 to 1.0. Default = 0.5.
Wet Mix 3	Volume of 3rd chorus tap. This tap is 90 degrees out of phase of the second tap. 0.0 to 1.0. Default = 0.5.
Delay	The LFO's delay in ms. 0.1 to 100.0. Default = 40.0 ms
Rate	The LFO's modulation rate in Hz. 0.0 to 20.0. Default = 0.8 Hz.
Depth	Chorus modulation depth. 0.0 to 1.0. Default = 0.03.
Feed Back	Chorus feedback. Controls how much of the wet signal gets fed back into the filter's buffer. 0.0 to 1.0. Default = 0.0.

Adding a chorus filter

To add a chorus filter to a given audio source just select the object in the inspector and then select Component->Audio->Audio Chorus Filter.

Hints

• You can tweak the chorus filter to create a flanger effect by lowering the feedback and decreasing the delay, as the flanger is a variant of the chorus.
• Creating a simple, dry echo is done by setting Rate and Depth to 0 and tweaking the mixes and Delay
