Chorus is a delay modulation effect that can be used to create more lush and larger sounds out the original audio signal. It does this by creating delayed copies of the audio signal, modulating their delay with an LFO and mixing it together with the original audio.
Set the frequency of the LFO. Higher frequencies means faster modulation.
Set the amount of modulation added to the incoming audio signal.
A highpass filter added to the effected signal.
Set the mix between the original and effected signal.
