another question : is it reliable to write sound processing code in LUA (i.e. call a LUA function from the Portaudio callback)? Not sure if the garbage collector would generate random clicks or pops in the audio stream when it takes too long.

Adrian here :)
I built a Lua 5.0 library to portaudio v18 about 12 months ago. It was a
pretty smooth integration, and supported most PA functionality, including
I'm happy to
you the code as-is, but
1/ It was only ever built on Windows,
2/ Documentation is scrappy (non-existant?),
3/ You will probably have to do a proper makefile (IIRC mine is hard-pathed
all over the place),
4/ There is no libsndfile binding for reading audio files.
If you are prepared to have a go, let me know.
If _anyone_ is interested in using / *nixising / polishing / tidying /
documenting PA Lua, I will start a LuaForge project for it, but I don't have
the time to work on it myself at present.
