BaseAudioContext: createConstantSource() method

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 createConstantSource() property of the BaseAudioContext interface creates a ConstantSourceNode object, which is an audio source that continuously outputs a monaural (one-channel) sound signal whose samples all have the same value.

Note: The ConstantSourceNode() constructor is the recommended way to create a ConstantSourceNode; see Creating an AudioNode.
