PannerNode

package js.html.audio

extends AudioNode › EventTarget

Available on js

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!

Variables

coneInnerAngle:Float

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

coneOuterAngle:Float

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.

coneOuterGain:Float

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.

distanceModel:DistanceModelType

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

maxDistance:Float

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

panningModel:PanningModelType

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

refDistance:Float

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

rolloffFactor:Float

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.

Methods

setOrientation (x:Float, y:Float, z:Float):Void

Defines the direction the audio source is playing in.

setPosition (x:Float, y:Float, z:Float):Void

Defines the position of the audio source relative to the listener (represented by an AudioListener object stored in the AudioContext.listener attribute.)

setVelocity (x:Float, y:Float, z:Float):Void

Defines the velocity vector of the audio source — how fast it is moving and in what direction. In a previous version of the specification, the PannerNode had a velocity that could pitch up or down AudioBufferSourceNodes connected downstream. This feature was not clearly specified and had a number of issues, so it was removed from the specification.
