WaveShaperNode.curve

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.

Syntax

var audioCtx = new AudioContext();
var distortion = audioCtx.createWaveShaper();
distortion.curve = myCurveDataArray; // myCurveDataArray is a Float32Array

Value

A Float32Array.

Example

See BaseAudioContext.createWaveShaper() for example code.
