Very lightweight, the whole thing downloads, compiles and runs almost instantly. After you go in the examples directory and run make, here's a little bash command to run and listen to each example in series while looking at its source:
shopt -s extglob
for f in ex_!(*.*); do ./$f; `play test.wav > /dev/null 2>&1 &`; less $f.c; done
ex_music is beautiful! But the source is not very expressive, even being familiar with DSP, a lot of the code has me guessing (well, it is expressive, but I guess the variable names are too short to my tastes).
I intentionally made Soundpipe simple at the expense of being not expressive. Some day, I hope to build a language on top of Soundpipe that is expressive. It also is conceivable to embed Soundpipe into more expressive music languages like ChucK, Csound, and Supercollider.
Also, some of the DSP code is ported directly from Csound, which has some very hard to read code in there (sorry about that.)
