HSoundFile - codecs for audio file reading/writing This library is based on Data.ByteString and Data.Binary to support lazy reading/writing of audio files. Requirements: GHC > 6.6. Other compilers are not currently supported due to a dependency on GHC's Float/Double library. Building: > runhaskell Setup.lhs configure > runhaskell Setup.lhs build > runhaskell Setup.lhs install I have achieved best performance with the following compiler options: -fvia-c -fexcess-precision -optc-O2 -optc-mmmx -optc-msse2 If possible, I recommend enabling mmx and sse2.
