New video: Let's Code MS DOS 0x39: Samples on the PC Speaker
The PC speaker is known for loud, harsh beeping noises. However with a little bit of trickery we can coerce it into producing almost arbitrary sounds. By manipulating it with the built in time chip, we can simulate a pulse width modulation, that allows us to play PCM digitized sounds, such as voice recordings.
