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 WaveShaperNode interface represents a non-linear distorter.

It is an AudioNode that uses a curve to apply a wave shaping distortion to the signal. Beside obvious distortion effects, it is often used to add a warm feeling to the signal.

A WaveShaperNode always has exactly one input and one output.
