Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
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.
