Field Summary

Fields

Modifier and Type	Field and Description
AudioProcessingEventHandler	onaudioprocess The following example shows basic usage of a ScriptProcessorNode to take a track loaded via AudioContext.decodeAudioData(), process it, adding a bit of white noise to each audio sample of the input track (buffer) and play it through the AudioDestinationNode.

Field Detail

onaudioprocess

@Nullable
public AudioProcessingEventHandler onaudioprocess

The following example shows basic usage of a ScriptProcessorNode to take a track loaded via AudioContext.decodeAudioData(), process it, adding a bit of white noise to each audio sample of the input track (buffer) and play it through the AudioDestinationNode. For each channel and each sample frame, the scriptNode.onaudioprocess function takes the associated audioProcessingEvent and uses it to loop through each channel of the input buffer, and each sample in each channel, and add a small amount of white noise, before setting that result to be the output sample in each case.
