But before you advocate that too hard, check to see the *real* capabilities of a one-bit PC speaker. You go on to give an example that uses PyAudio and a sine wave, not the timer chip's "beep" functionality. Try getting some recordings of a half dozen or so computers making a beep at 440Hz. Then do some analysis on the recordings and see whether they're actually within 1Hz of that. (And that's aside from the fact that quite a number of computers will show up completely silent, due to either not having an internal speaker, or not letting you use it.)
