This is something I discovered by importing a 16-color bitmap image as raw data into Audacity, and setting the playback speed so that part of it sounds like a 120 hz square wave. I then started a 119 hz sawtooth wave in my internet browser, and played them both at the same time. The result is this. Video was recorded by me on August 16, 2025, using OBS Studio 31.1.1 on my Beelink SEi mini-PC. Edited by me using Microsoft Clipchamp.
