The PannerNode interface 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!

PannerNode()
Creates a new PannerNode object instance.
Inherits properties from its parent, AudioNode.
Note: The orientation and position value are set and retrieved using different syntaxes, since they're stored as AudioParam values. Retrieval is done by accessing, for example, PannerNode.positionX. While setting the same property is done with PannerNode.positionX.value. This is why these values are not marked read only, which is how they appear in the WebIDL.
PannerNode.coneInnerAngle
A double value describing the angle, in degrees, of a cone inside of which there will be no volume reduction.
PannerNode.coneOuterAngle
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 property.
PannerNode.coneOuterGain
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.
PannerNode.distanceModel
An enumerated value determining which algorithm to use to reduce the volume of the audio source as it moves away from the listener. Possible values are "linear", "inverse" and "exponential". The default value is "inverse".
PannerNode.maxDistance
A double value representing the maximum distance between the audio source and the listener, after which the volume is not reduced any further.
PannerNode.orientationX
Represents the horizontal position of the audio source's vector in a right-hand Cartesian coordinate system. While this AudioParam cannot be directly changed, its value can be altered using its value property. The default is value is 1.
PannerNode.orientationY
Represents the vertical position of the audio source's vector in a right-hand Cartesian coordinate system. The default is 0. While this AudioParam cannot be directly changed, its value can be altered using its value property. The default is value is 0.
PannerNode.orientationZ
Represents the longitudinal (back and forth) position of the audio source's vector in a right-hand Cartesian coordinate system. The default is 0. While this AudioParam cannot be directly changed, its value can be altered using its value property. The default is value is 0.
PannerNode.panningModel
An enumerated value determining which spatialization algorithm to use to position the audio in 3D space.
PannerNode.positionX
Represents the horizontal position of the audio in a right-hand Cartesian coordinate system. The default is 0. While this AudioParam cannot be directly changed, its value can be altered using its value property. The default is value is 0.
PannerNode.positionY
Represents the vertical position of the audio in a right-hand Cartesian coordinate system. The default is 0. While this AudioParam cannot be directly changed, its value can be altered using its value property. The default is value is 0.
PannerNode.positionZ
Represents the longitudinal (back and forth) position of the audio in a right-hand Cartesian coordinate system. The default is 0. While this AudioParam cannot be directly changed, its value can be altered using its value property. The default is value is 0.
PannerNode.refDistance
A double value representing the reference distance for reducing volume as the audio source moves further from the listener. For distances greater than this the volume will be reduced based on rolloffFactor and distanceModel.
PannerNode.rolloffFactor
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.
Inherits methods from its parent, AudioNode.
PannerNode.setPosition() Deprecated
Defines the position of the audio source relative to the listener (represented by an AudioListener object stored in the BaseAudioContext.listener attribute.)
PannerNode.setOrientation() Deprecated
Defines the direction the audio source is playing in.
See BaseAudioContext.createPanner() for example code.
