The StereoPannerNode interface of the Web Audio API represents a simple stereo panner node that can be used to pan an audio stream left or right. It is an AudioNode audio-processing module that positions an incoming audio stream in a stereo image using a low-cost equal-power panning algorithm.
The pan property takes a unitless value between -1 (full left pan) and 1 (full right pan). This interface was introduced as a much simpler way to apply a simple panning effect than having to use a full PannerNode.
