StereoPannerNode
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2021.
TheStereoPannerNode interface of theWeb Audio API represents a simple stereo panner node that can be used to pan an audio stream left or right. It is anAudioNode audio-processing module that positions an incoming audio stream in a stereo image using a low-cost equal-powerpanning algorithm.
Thepan property takes a unitless value between-1 (full left pan) and1 (full right pan). This interface was introduced as a much simpler way to apply a simple panning effect than having to use a fullPannerNode.
