public class AudioBuffer
extends JsObject

The AudioBuffer interface represents a short audio asset residing in memory, created from an audio file using the AudioContext.decodeAudioData() method, or from raw data using AudioContext.createBuffer(). Once put into an AudioBuffer, the audio can then be played by being passed into an AudioBufferSourceNode.

Constructor Summary

Constructors

Constructor and Description
AudioBuffer(AudioBufferOptions options) The AudioBuffer constructor of the Web Audio API creates a new AudioBuffer object.

Method Summary

Modifier and Type	Method and Description
void	copyFromChannel(Float32Array destination, int channelNumber) The copyFromChannel() method of the AudioBuffer interface copies the audio sample data from the specified channel of the AudioBuffer to a specified Float32Array.
void	copyFromChannel(Float32Array destination, int channelNumber, int bufferOffset) The copyFromChannel() method of the AudioBuffer interface copies the audio sample data from the specified channel of the AudioBuffer to a specified Float32Array.
void	copyToChannel(Float32Array source, int channelNumber) The copyToChannel() method of the AudioBuffer interface copies the samples to the specified channel of the AudioBuffer, from the source array.
void	copyToChannel(Float32Array source, int channelNumber, int bufferOffset) The copyToChannel() method of the AudioBuffer interface copies the samples to the specified channel of the AudioBuffer, from the source array.
double	duration() A double.
Float32Array	getChannelData(int channel) The getChannelData() method of the AudioBuffer Interface returns a Float32Array containing the PCM data associated with the channel, defined by the channel parameter (with 0 representing the first channel).
int	length() The length property of the AudioBuffer interface returns an integer representing the length, in sample-frames, of the PCM data stored in the buffer.
int	numberOfChannels() An integer.
float	sampleRate() A floating-point value indicating the current sample rate of the buffers data, in samples per second.
