  Some apparent links don't appear to work at the start of the page, and I couldn't see any links to listen to the output?

  The article ends to a link to a video that shows off the technique and it blows my mind the Spectrum beeper could produce this: https://www.youtube.com/watch?v=7cOu32m3wvQ

    I created a program like that back in the day. In my case, I recorded my voice through the "MIC" input and played it back through the TV. A few seconds of sampled audio required the entire available memory. While I fully understood what was going on, I thought it was magical that the Spectrum could "speak with my voice".

    Sounds pretty good. Reminds me of the Demo Scene and the types of music they were able to create.

  Turns out 1-Bit encoding is the most efficient solution, even for the highest end of audio quality: https://en.wikipedia.org/wiki/Delta-sigma_modulation
