| How to run |
The executable has been built on a Raspberry Pi 400 using Raspberry Pi
OS (Bullseye), but it should also run fine on a Raspberry Pi 4. It may
also run on a number of other Pis without recompilation, but I haven't
tested this, so no promises.
To hear some music, you'll first need to take ownership of the file. If

you can enter '$ ./sine-time' to listen to some cool tunes. It'll also

It uses a custom-built executable wavetable synthesizer program, which
you can find the source code for here:
The song itself is stereo, 44.1kHz, and uses 7 oscillator voices and 1
drum channel. The wavetables are generated at runtime, as are the drum
sounds, which use a single oscillator and a simple LFSR for noise.

Huge thanks to all of the (numerous) sources I used when studying up on
DSP programming techniques (credited in the code) and Revision for
organising such a fantastic event.
I hope you enjoy the music!
