Where is /dev/audio on OS X?

I don't know if there's a way to play it real-time. I was trying to install sox from homebrew, but it can't grab its libogg dependency, downloads.xiph.org isn't working right now, seemingly.

However, you can do this:

  $ ./soundprog > temp.au
hit CTRL-C (Hit it fast! You don't need it to run very long, and it will write to the resulting file very very quickly! Consider modifying the code to have a limit on the for loop.)

Then open the resulting .au file in Audacity (http://audacity.sourceforge.net/). It'll play fine.

Not as simple just writing to a sound device, but it works.

Ok, looks like xiph.org was just having a hiccup. You can do it real time with sox.

First, Get sox. I prefer homebrew for Unix type stuff (http://mxcl.github.com/homebrew/), but it's likely MacPorts, Fink, and other sources have sox available too. If using Homebrew, just:

  $ brew install sox
Compile your program. Run it like this:

  $ ./soundprog | sox -r 8000 -t u8 - -d
Voila, just like having a sound device. You can play with the 8000 to make it faster or slower (modifying the pitch as well).

I think you'd have to write some kind of CoreAudio stub.

But if you just want to play with this stuff, see the Javascript version here:
