I haven't found multitrack audio recording applications written in Haskell. These are usually written in C++ using Jack audio or ASIO. This probably means that it is not a good idea to write real time audio applications in Haskell at the moment.
There are at least two Haskell bindings to JACK. I wrote one of them. The big issue is (no surprise) garbage collection. Audio stuff can generate a lot of garbage fast if you aren't careful. And the stop-the-world collection can happen at unfortunate times. The uvector library might help things -- but ultimately Haskell would need a more realtime friendly garbage collector. So, realtime audio can be done in Haskell today, but is is definitely fragile at best. - jeremy
