gcc -o lolsound lolsound.c
./lolsound > /dev/dsp

First one to hack this into saying "Have you read your SICP today?" gets an internet.

I think I've finally understood^[1] how basic sound works. It's like a digital raw description of actual analogic sound. But, damn, that imples that i must build the waves myself with sin(). What if i want to play two different tones simultaneously?

Does anyone know a good introduction to ``sound theory''? Because I'd prefer reading something myself than filling this thread with questions. _{Due to geographical conditions i'm unable to buy books, so links are preferred. But I don't know what to search.}

^[1]Being the faggot I am, I had to do this:
