PannerNode class abstract

The PannerNode defines an audio-processing object that represents the location, direction, and behavior of an audio source signal in a simulated physical space. This AudioNode uses right-hand Cartesian coordinates to describe the source's position as a vector and its orientation as a 3D directional cone.

A PannerNode always has exactly one input and one output: the input can be mono or stereo but the output is always stereo (2 channels); you can't have panning effects without at least two audio channels!

The PannerNode defines a spatial position and direction for a given
signal.

Number of inputs 1
Number of outputs 1
Channel count mode "clamped-max"
Channel count 2
Channel interpretation "speakers"

Properties

channelCount int
The channelCount property of the AudioNode represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node.
getter/setter pairinherited
channelCountMode ChannelCountMode
The channelCountMode property of the AudioNode represents an enumerated value describing the way channels must be matched between the node's inputs and outputs.
getter/setter pairinherited
channelInterpretation ChannelInterpretation
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.
getter/setter pairinherited
coneInnerAngle double
The coneInnerAngle property of the PannerNode is a double value describing the angle, in degrees, of a cone inside of which there will be no volume reduction.
getter/setter pair
coneOuterAngle double
The coneOuterAngle property of the PannerNode 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 PannerNode.coneOuterGain property.
getter/setter pair
coneOuterGain double
The coneOuterGain property of the PannerNode is a double value, describing the amount of volume reduction outside the cone, defined by the PannerNode.coneOuterAngle attribute.
getter/setter pair
context BaseAudioContext
The read-only context property of the AudioNode returns the associated BaseAudioContext, that is the object representing the processing graph the node is participating in.
no setterinherited
distanceModel DistanceModelType
The distanceModel property of the PannerNode is an enumerated value determining which algorithm to use to reduce the volume of the audio source as it moves away from the listener.
getter/setter pair
hashCode int
The hash code for this object.
no setterinherited
maxDistance double
The maxDistance property of the PannerNode is a double value representing the maximum distance between the audio source and the listener, after which the volume is not reduced any further. This value is used only by the linear distance model.
getter/setter pair
numberOfInputs int
The numberOfInputs property of the AudioNode returns the number of inputs feeding the node. Source nodes are defined as nodes having a numberOfInputs property with a value of 0.
no setterinherited
numberOfOutputs int
The numberOfOutputs property of the AudioNode returns the number of outputs coming out of the node. Destination nodes — like AudioDestinationNode — have a value of 0 for this attribute.
no setterinherited
orientationX AudioParam
The orientationX property of the PannerNode indicates the X (horizontal) component of the direction in which the audio source is facing, in a 3D Cartesian coordinate space.
no setter
orientationY AudioParam
The orientationY property of the PannerNode interface indicates the Y (vertical) component of the direction the audio source is facing, in 3D Cartesian coordinate space.
no setter
orientationZ AudioParam
The orientationZ property of the PannerNode interface indicates the Z (depth) component of the direction the audio source is facing, in 3D Cartesian coordinate space.
no setter
panningModel PanningModelType
The panningModel property of the PannerNode is an enumerated value determining which spatialization algorithm to use to position the audio in 3D space.
getter/setter pair
positionX AudioParam
The positionX property of the PannerNode specifies the X coordinate of the audio source's position in 3D Cartesian coordinates, corresponding to the horizontal axis (left-right).
no setter
positionY AudioParam
The positionY property of the PannerNode specifies the Y coordinate of the audio source's position in 3D Cartesian coordinates, corresponding to the vertical axis (top-bottom). The complete vector is defined by the position of the audio source, given as (PannerNode.positionX, PannerNode.positionY, PannerNode.positionZ), and the orientation of the audio source (that is, the direction in which it's facing), given as (PannerNode.orientationX, PannerNode.orientationY, PannerNode.orientationZ).
no setter
positionZ AudioParam
The positionZ property of the PannerNode specifies the Z coordinate of the audio source's position in 3D Cartesian coordinates, corresponding to the depth axis (behind-in front of the listener). The complete vector is defined by the position of the audio source, given as (PannerNode.positionX, PannerNode.positionY, PannerNode.positionZ), and the orientation of the audio source (that is, the direction in which it's facing), given as (PannerNode.orientationX, PannerNode.orientationY, PannerNode.orientationZ).
no setter
refDistance double
The refDistance property of the PannerNode is a double value representing the reference distance for reducing volume as the audio source moves further from the listener – i.e. the distance at which the volume reduction starts taking effect. This value is used by all distance models.
getter/setter pair
rolloffFactor double
The rolloffFactor property of the PannerNode 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. The rolloffFactor property's default value is 1.
getter/setter pair
runtimeType Type
A representation of the runtime type of the object.
no setterinherited

Methods

connect(AudioNode destinationNode, [int output, int input]) AudioNode
The connect() method of the AudioNode 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). See also AudioNode.connectParam
inherited
connectParam(AudioParam destinationParam, [int output, int input]) → void
This is a variant of AudioNode.connect with a DestinationParam argument instead of an AudioNode. Note : The W3C recommandation uses just one verb for both.
inherited
disconnect([AudioNode destinationParamOrOutput, int output, int input]) → void
The disconnect() method of the AudioNode lets you disconnect one or more nodes from the node on which the method is called. See also AudioNode.disconnectParam
inherited
disconnectParam(AudioParam destinationParam, [int output, int input]) → void
This is a variant of AudioNode.disconnect with a DestinationParam argument instead of an AudioNode. Note : The W3C recommandation uses just one verb for both.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
setOrientation(num x, num y, num z) → void

Note: The suggested replacement for this deprecated method is to instead set the orientationX, orientationY, and orientationZ attributes directly.

setPosition(num x, num y, num z) → void

Note: The suggested replacement for this deprecated method is to instead set the positionX, positionY, and positionZ attributes directly.

toString() String
A string representation of this object.
