trait AudioNode extends EventTarget

The AudioNode interface is a generic interface for representing an audio processing module like an audio source (e.g. an HTML <audio> or <video> element, an OscillatorNode, etc.), the audio destination, intermediate processing module (e.g. a filter like BiquadFilterNode or ConvolverNode), or volume control (like GainNode).

An AudioNode has inputs and outputs, each with a given amount of channels. An AudioNode with zero inputs and one or multiple outputs is called a source node. The exact processing done varies from one AudioNode to another but, in general, a node reads its inputs, does some audio-related processing, and generates new values for its outputs, or simply lets the audio pass through (for example in the AnalyserNode, where the result of the processing is accessed separately).

Different nodes can be linked together to build a processing graph. Such a graph is contained in an AudioContext. Each AudioNode participates in exactly one such context. In general, processing nodes inherit the properties and methods of AudioNode, but also define their own functionality on top. See the individual node pages for more details, as listed on the Web Audio API homepage.

    The EventTarget.addEventListener() method registers the specified listener on the EventTarget it's called on.

    The EventTarget.addEventListener() method registers the specified listener on the EventTarget it's called on. The event target may be an Element in a document, the Document itself, a Window, or any other object that supports events (such as XMLHttpRequest).

  6. var channelCount: Int

    Permalink

    Represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node.

    Represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node. Its usage and precise definition depend on the value of AudioNode.channelCountMode.

  7. var channelCountMode: Int

    Permalink

    Represents an enumerated value describing the way channels must be matched between the node's inputs and outputs.

  8. var channelInterpretation: String

    Permalink

    Represents an enumerated value describing the meaning of the channels.

    Represents an enumerated value describing the meaning of the channels. This interpretation will define how audio up-mixing and down-mixing will happen.

    The possible values are "speakers" or "discrete".

    Allows us to connect one output of this node to one input of an audio parameter.

    Permalink

    Allows us to connect one output of this node to one input of another node.

  12. val context: AudioContext

    Permalink

    Returns the associated AudioContext, that is the object representing the processing graph the node is participating in.

  13. def disconnect(output: AudioNode = js.native): Unit

    Permalink

    Allows us to disconnect the current node from another one it is already connected to.

    Allows us to disconnect the current node from another one it is already connected to.

    output

    The index describing which output of the AudioNode is going to be disconnected.

  14. def dispatchEvent(evt: Event): Boolean

    Dispatches an Event at the specified EventTarget, invoking the affected EventListeners in the appropriate order.

    Dispatches an Event at the specified EventTarget, invoking the affected EventListeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) apply to events dispatched manually with dispatchEvent().
