if you get it to work

As a spoiled Java programmer, this new role as pioneer is a bit intimidating, but I will give it a shot. :)

I downloaded the portaudio v19 source and I'm attempting to build it. Apparently I have to register my Visual Studio Express with Microsoft. Deeper down the rabbit hole... (Interesting aside, on the registration form under "What programming language topics are you interested in?" neither F# or Haskell are listed)

For doing cross-platform development, I would strongly recommend that you use MinGW (or cygwin) in preference to Visual Studio Express. This is because most Unix/Linux packages, and thus most cross-platform packages, are designed to be built with the GNU compiler toolchain (i.e. configure, make, make install), and getting them to work with Visual Studio can be a chore. I also would use PortAudio for what you describe, and have had good experience with it on OSX. Sox is a good choice as well if you don't mind piping output to another program. *shameless plug* you could also use hCsound, although it's probably higher-level than what you're looking for. Installing on Windows is tricky too, but you only need to do so once. John
