{{ APIRef("Web Audio API") }}
The WaveShaperNode interface represents a non-linear distorter.
It is an {{domxref("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.

- {{domxref("WaveShaperNode.oversample")}}
- : An enumerated value indicating if oversampling must be used. Oversampling is a technique for creating more samples (up-sampling) before applying the distortion effect to the audio signal.
