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 PeriodicWave interface defines a periodic waveform that can be used to shape the output of an OscillatorNode.
PeriodicWave has no inputs or outputs; it is used to define custom oscillators when calling OscillatorNode.setPeriodicWave(). The PeriodicWave itself is created/returned by BaseAudioContext.createPeriodicWave.
