Properties

duration

val duration: Double

The duration property of the AudioBuffer interface returns a double representing the duration, in seconds, of the PCM data stored in the buffer.

length

val length: Int

The length property of the AudioBuffer interface returns an integer representing the length, in sample-frames, of the PCM data stored in the buffer.

numberOfChannels

val numberOfChannels: Int

The numberOfChannels property of the AudioBuffer interface returns an integer representing the number of discrete audio channels described by the PCM data stored in the buffer.

sampleRate

val sampleRate: Float

The sampleRate property of the AudioBuffer interface returns a float representing the sample rate, in samples per second, of the PCM data stored in the buffer.

Functions

copyFromChannel

fun copyFromChannel(destination: Float32Array<ArrayBuffer>, channelNumber: Int, bufferOffset: Int = definedExternally)

The copyFromChannel() method of the channel of the AudioBuffer to a specified ``js-nolint copyFromChannel(destination, channelNumber, startInChannel) `` - destination - : A Float32Array to copy the channel's samples to.

copyToChannel

fun copyToChannel(source: Float32Array<ArrayBuffer>, channelNumber: Int, bufferOffset: Int = definedExternally)

The copyToChannel() method of the AudioBuffer interface copies the samples to the specified channel of the AudioBuffer, from the source array.

getChannelData

fun getChannelData(channel: Int): Float32Array<ArrayBuffer>

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).
