Sound Chip
TIC-80 has four audio channels supplied by its virtual sound chip. These are updated by the sfx() and music() functions in the TIC-80 API. But you can also use poke() and poke4() to make noises.
The music is usually created with the built-in audio editors, but one can code their own music driver and write to the audio ram.
Every frame (60hz), on all 4 audio channels, the 4 bit, 32 length waveform can be changed, which could theoretically be used to produce dynamic sound using various audio synthesis methods.
