This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The curve property of the WaveShaperNode interface is a Float32Array of numbers describing the distortion to apply.
The mid-element of the array is applied to any signal value of 0, the first one to signal values of -1, and the last to signal values of 1; values lower than -1 or greater than 1 are treated like -1 or 1 respectively.
If necessary, intermediate values of the distortion curve are linearly interpolated.
Note: The array can be a null value: in that case, no distortion is applied to the input signal.
A Float32Array.
See BaseAudioContext.createWaveShaper() for example code.
