@cloudskater @OwOarchist a standard definition video signal has a bandwidth of around 5MHz and is usually digitized at a sample rate of 13MHz. Even with a sound card that goes up to 196khz you only have about one fiftieth of the bandwidth required for a video signal.

You *can* still generate sound that will result in visible patterns, but don’t expect any actual images

@frittoBee it’s not really playing a CD, its cutting a groove like on a vinyl record into the CD and then playing it on a record player.

@ICastFist very very short ones maybe. Everything but the very outside edge is already outside of the range designed to be played on a regular turntable, so the surface speed is very low and the angle of the tone arm gets kinda extreme. My automatic turntable won’t play these at all unless you’re very careful since every quick movement of the tone arm that far in makes it think it’s hit the runout groove and stops playback.

oh hey, that’s me! And the video is also on fedi! https://pawb.fun/@slyka/113028002924181756
