Based on the Apple Developer article Playing Sounds with the Web Audio API, sound is read from a file on disk, passed through an audio filter, and looped while the audio spectrum is drawn on an HTML canvas.

Please note that the volume slider adjusts the output volume relative to the current system setting.
