I made a visualizer using the Desmos web graphing app to see what happens when Casey switches from a 256 Hz to a 512 Hz tone using the A button on his gamepad (Day 009). I thought I'd share it here in case anyone else is wondering what the waveform looks like. Just slide the B (boundary) slider to see it in action!
