ChorusProcessor
This module is responsible for applying the chorus effect to the audio. It is used by the synthesizers, but it can also be used standalone.
Implementation
The chorus effect comprises a channel splitter, then a chain of delay nodes, their delay times being driven by low frequency oscillators, then getting merged back into a stereo output.
Initialization
- context - the BaseAudioContext to use.
- config - an optional configuration. This can be changed later. Described below.
Chorus configuration
nodesAmount
The amount of delay nodes (for each channel) and the corresponding oscillators.
defaultDelay
The initial delay, in seconds.
delayVariation
The difference between delays in the delay nodes.
stereoDifference
The difference of delays between two channels (added to the right channel).
oscillatorFrequency
The initial delay time oscillator frequency, in Hz.
oscillatorFrequencyVariation
The difference between frequencies of oscillators, in Hz.
oscillatorGain
How much will oscillator alter the delay in delay nodes, in seconds.
