I don't know of any such libs on hackage, but I think your best bet would be to find a C library which does what you want, then write an FFI binding to it. Not only will you get the functionality you want, but you could contribute a binding-library to hackage which would be _way awesome_. You can find resources about FFI in Real World Haskell (google it, the book is available free online), and of course Hoogle will be helpful. /Joe Bernhard Lehnert wrote:
Hi,
would there, by any chance, be something like a simple and well documented way to read sound from a microphone on the soundcard and perform a fft or sth. to find the pitch of a sound?
There is a whole lot of so called "guitar tuner" progs doing that, but any simple to use library for haskell? (Preferebly available on Windows, too.) Looking through hackage it seems to me that there is a wealth of libs for sound and music synthesis but not so much for sound analysis. Good online reading advice on the topic (be it haskell or not) would also be greatly appreciated (maybe some handbook for the dsp package?).
Thanks, Bernhard
