PannerNode extension type

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!

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 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.

getter/setter pair, inherited

channelCountMode ↔ ChannelCountMode

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.

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.
