waveChunk :: String -> Maybe WAVE_CHUNK Source

Convert a string to WAVE_CHUNK type

chunkToString :: WAVE_CHUNK -> String Source

Convert a WAVE_CHUNK to the representative string

dictReadFormat :: Int -> WAVEDict -> IterateeG L Word8 IO (Maybe AudioFormat) Source

Read the specified format chunk from the WAVE dictionary
