AudioBufferSourceNode
The AudioBufferSourceNode interface is an AudioScheduledSourceNode which represents an audio source consisting of in-memory audio data, stored in an AudioBuffer.
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.
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. For example, this setting defines how a mono input will be up-mixed to a stereo or 5.1 channel output, or how a quad channel input will be down-mixed to a stereo or mono output.
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 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 loopStart property. This is only used if the loop property is true.
The numberOfInputs property of the AudioNode interface returns the number of inputs feeding the node. Source nodes are defined as nodes having a numberOfInputs property with a value of 0.
The numberOfOutputs property of the AudioNode interface returns the number of outputs coming out of the node. Destination nodes — like AudioDestinationNode — have a value of 0 for this attribute.
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
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.
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.
The start() method on AudioScheduledSourceNode schedules a sound to begin playback at the specified time. If no time is specified, then the sound begins playing immediately.
