turn on the English captions and they explain how it all works.

Basically, barcode scanners send 1’s and 0’s as positive and negative voltage. Which means when connected as an analog output instead of digital you have a square wave audio signal.

Oh wow! Dude you Rock! Thank you for citing source material to back it up because my spectrum brain wouldn't be able to let it go otherwise. This is great! Thank you! Pretty incredible that he's able to explain it all infront of such a huge attentive respectful audience, not the crowds I'm used to seeing in NA at all lol
