WaveShaperNode: curve property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2021.

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.
