Capturing audio input from microphone, with Haskell?

Question

Is there a mature library that could enable audio input and output and work within Haskell? (A nice wrapper is fine, of course.)

I'm looking for something that can easily capture microphone input and, perhaps, play various audio files as well.

Answer 1

easily capture microphone input and, perhaps, play various audio files as well..

It will strongly depend on your OS platform: there are standard C libraries for this functionality on each OS, and you'll be looking for Haskell bindings to them (e.g. PulseAudio, etc). Look in the Sound category on Hackage:

• http://hackage.haskell.org/packages/archive/pkg-list.html#cat:sound

E.g. HSndFile for audio file writing, http://hackage.haskell.org/package/HSoundFile

Answer 2

the module pulse-simple exposes bindings to capture sound from the microphone, see the second example at the top of the page;
https://hackage.haskell.org/package/pulse-simple-0.1.13/docs/Sound-Pulse-Simple.html
pulse audio libraries required by cabal are obtainable via cygwin (search "pulse" in the cygwin installer).

there is a also binding to sox, which looks promising. https://hackage.haskell.org/package/sox

im sure there are other api wrappers to be found in hackage sound category.

for linux there is a binding to jack, has "unix" as a dependency, it WILL NOT build on windows...
