I can't really answer this very sensibly with my extremely limited
experience in the area, but I will try anyway!
I think that performance problems may hit you sooner than you might hope
for real-time stuff. I was slightly surprised that my naive first attempt
at audio-type programming with Ocaml failed to fill buffers fast enough
with a bytecode-compiled executable, though native code is fine (this
was on a 1GHz Athlon, YMMV). The trancendental functions and non-tail
recursive functions I used might have something to do with it though.
As for the manipulation of sound itself, yes, Ocaml is a lovely
language! It may be better to stick with an imperative rather than
functional programming style though, for reasons of performance. Also,
under Linux, the low-level ioctl calls are a total pain, and require
interfacing to C.
You can have a look at this as an example if you like, though I don't
expect it will be very useful to you:
http://panic.cs.bris.ac.uk/~jules/beepy.tar.bz2
It needs lablgtk2, and probably won't work on anything but Linux. It's
only been tested on x86. The sound.ml/sountctl.c files might be a useful
starting point for some sort of sound output library, if you can't find
anything else more suitable.
Cheers,
Julian
