I've seen some bindings once, which weren't complete, but considering that the JACK API is about as simple as you can get (and plain C), it's trivial to interface to, no matter if you do the ffi imports yourself or not. gstreamer absolutely won't help you interfacing with any professional Linux audio app. Jack _is_ the interface... and the best thing you could wish for.

These are cross-platform, though OpenAL can be problematic to build correctly. I also wrote simple CoreAudio playback (that's on OSX) but it is not exactly release quality; tell me if you would like the code. DirectSound on Windows isn't hard either.

Re: [haskell-art] what do people use for audio output
Hi Henning, Thanks for replying. I wasn't aware of the SOX method. Do you still use this (in new code), or do you mostly use ALSA?

The technique, that I got to work fastest, was feeding 'sox' via a pipe: http://hackage.haskell.org/packages/archive/synthesizer/0.0.3/doc/html/Sox-Play.html Now I can also play sounds via ALSA: http://code.haskell.org/alsa/Sound/Alsa.hs People are also working on PortAudio, but I haven't tested that: http://haskell.org/haskellwiki/PortAudio ___ haskell-art mailing list haskell-art@lurk.org http://lists.lurk.org/mailman/listinfo/haskell-art
