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