Description

Encode lazy bytestrings to wave format, and decode lazy bytestrings in wave format to a WaveFile datum.

Synopsis

newtype WaveFile = WaveFile [WaveChunk] data WaveChunk = WaveFormat { format :: SndFileInfo } | WaveData { waveData :: ByteString chunkLength :: Integer } | WaveMeta { metaData :: ByteString chunkLength :: Integer } | UnknownWaveChunk { chunkType :: ByteString unparsedData :: ByteString chunkLength :: Integer } getWaveFile :: Monad m => ByteString -> AudioMonad m WaveFile toWaveFile :: (SndFileCls a, Monad m) => a -> AudioMonad m WaveFile isWaveFile :: ByteString -> Bool

Encode/decode functions

getWaveFile :: Monad m => ByteString -> AudioMonad m WaveFile Source

return a WaveFile from a bytestring (including header)

toWaveFile :: (SndFileCls a, Monad m) => a -> AudioMonad m WaveFile Source

Create a WaveFile from a SndFileCls

isWaveFile :: ByteString -> Bool Source

determine (based on header information) if the bytestring is a wave file.
