Properties

The buffer property of the AudioBufferSourceNode interface provides the ability to play back audio using an AudioBuffer as the source of the sound data.

The channelCount property of the AudioNode interface represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node.

Link copied to clipboard

The channelCountMode property of the AudioNode interface represents an enumerated value describing the way channels must be matched between the node's inputs and outputs.

The channelInterpretation property of the AudioNode interface represents an enumerated value describing how input channels are mapped to output channels when the number of inputs/outputs is different.

The read-only context property of the AudioNode interface returns the associated BaseAudioContext, that is the object representing the processing graph the node is participating in.

The detune property of the AudioBufferSourceNode interface is a k-rate AudioParam representing detuning of oscillation in cents.

The loop property of the AudioBufferSourceNode interface is a Boolean indicating if the audio asset must be replayed when the end of the AudioBuffer is reached.

The loopEnd property of the AudioBufferSourceNode interface specifies is a floating point number specifying, in seconds, at what offset into playing the AudioBuffer playback should loop back to the time indicated by the AudioBufferSourceNode.loopStart property.

The loopStart property of the AudioBufferSourceNode interface is a floating-point value indicating, in seconds, where in the AudioBuffer the restart of the play must happen.

The numberOfInputs property of the AudioNode interface returns the number of inputs feeding the node.

Link copied to clipboard

The numberOfOutputs property of the AudioNode interface returns the number of outputs coming out of the node.

The playbackRate property of the AudioBufferSourceNode interface Is a k-rate AudioParam that defines the speed at which the audio asset will be played.

Functions

fun connect(destinationParam: AudioParam, output: Int = definedExternally)

fun connect(destinationNode: AudioNode, output: Int = definedExternally, input: Int = definedExternally): AudioNode

The connect() method of the AudioNode interface lets you connect one of the node's outputs to a target, which may be either another AudioNode (thereby directing the sound data to the specified node) or an AudioParam, so that the node's output data is automatically used to change the value of that parameter over time.

The disconnect() method of the AudioNode interface lets you disconnect one or more nodes from the node on which the method is called.

fun disconnect(output: Int)
fun disconnect(destinationNode: AudioNode)
fun disconnect(destinationParam: AudioParam)
fun disconnect(destinationNode: AudioNode, output: Int)
fun disconnect(destinationParam: AudioParam, output: Int)
fun disconnect(destinationNode: AudioNode, output: Int, input: Int)

fun start(when: Double = definedExternally, offset: Double = definedExternally, duration: Double = definedExternally)

The start() method of the AudioBufferSourceNode Interface is used to schedule playback of the audio data contained in the buffer, or to begin playback immediately.

fun start(when: Double = definedExternally)

The start() method on AudioScheduledSourceNode schedules a sound to begin playback at the specified time.

fun stop(when: Double = definedExternally)

The stop() method on AudioScheduledSourceNode schedules a sound to cease playback at the specified time.
