PannerNode

Defines the direction the audio source is playing in. This can have a big effect if the sound is very directional — controlled by the three cone-related attributes PannerNode.coneInnerAngle, PannerNode.coneOuterAngle, and PannerNode.coneOuterGain. In such a case, a sound pointing away from the listener can be very quiet or even silent.

The three parameters x, y and z are unitless and describe a direction vector in 3D space using the right-hand Cartesian coordinate system.

The default value of the direction vector is (1, 0, 0).

Defines the position of the audio source relative to the listener (represented by an AudioListener object stored in the AudioContext.listener attribute.) The three parameters x, y and z are unitless and describe the source's position in 3D space using the right-hand Cartesian coordinate system.

The setPosition() method's default value of the position is (0, 0, 0).

Defines the velocity vector of the audio source — how fast it is moving and in what direction.

The velocity relative to the listener is used to control the pitch change needed to conform with the Doppler effect due to the relative speed.

As the vector controls both the direction of travel and its velocity, the three parameters x, y and z are expressed in meters per second.

The default value of the velocity vector is (0, 0, 0).

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).

This implementation accepts a settings object of type EventListenerOptions.

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).

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

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

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

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().

Removes the event listener previously registered with EventTarget.addEventListener.

This implementation accepts a settings object of type EventListenerOptions.

Removes the event listener previously registered with EventTarget.addEventListener.

Is a double value describing the angle, in degrees, of a cone inside of which there will be no volume reduction.

Is a double value describing the angle, in degrees, of a cone outside of which the volume will be reduced by a constant value, defined by the coneOuterGain attribute.

Is a double value describing the amount of volume reduction outside the cone defined by the coneOuterAngle attribute.

Its default value is 0, meaning that no sound can be heard.

Is an enumerated value determining which algorithm to use to reduce the volume of the audio source as it moves away from the listener.

Is a double value representing the maximum distance between the audio source and the listener, after which the volume is not reduced any further.

Is an enumerated value determining which spatialisation algorithm to use to position the audio in 3D space.

Is a double value representing the reference distance for reducing volume as the audio source moves further from the listener.

Is a double value describing how quickly the volume is reduced as the source moves away from the listener. This value is used by all distance models.

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.

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

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".

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

Returns the number of inputs feeding the node. Source nodes are defined as nodes having a numberOfInputs property with a value of 0.

Returns the number of outputs coming out of the node. Destination nodes — like AudioDestinationNode — have a value of 0 for this attribute.
