WaveShaperNode: curve property

{{ APIRef("Web Audio API") }}

The curve property of the {{ domxref("WaveShaperNode") }} interface is a {{jsxref("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.

Value

A {{jsxref("Float32Array")}}.

Examples
