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".

More mind blowing, that entry took _second_ place! First place would probably break my brain for the day so I won't look it up.
Sounds pretty good. Reminds me of the Demo Scene and the types of music they were able to create.

Reminds me of an experiment that we did with TI calculators in the late 90s. Someone found that you can put an AM radio next to the calculator and it would beep based on what instructions were run on the Z80. There were some demos that played songs via 1 bit beeps like this, but since games actually have to run instructions, you couldnt reliably play background music during gameplay.
It would be interesting if someone could implement or adapt Roman Black's BTC algorithm to model the Speccy beeper.
