Audio Chorus Filter

Switch to Scripting

The Audio Chorus Filter takes an Audio ClipA container for audio data in Unity. Unity supports mono, stereo and multichannel audio assets (up to eight channels). Unity can import .aif, .wav, .mp3, and .ogg audio file format, and .xm, .mod, .it, and .s3m tracker module formats. More info

and processes it creating a chorus effect.

Details

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
