Read the last data chunk in the WAVE dictionary.

dict_read_data :: Int -> WAVEDict -> IterateeGM L Word8 IO (Maybe [Double])

Read the specified data chunk from the WAVE dictionary.

dict_process_data :: Int -> WAVEDict -> IterateeGM L Double IO a -> IterateeGM L Word8 IO (Maybe a)

Read the specified data chunk from the dictionary, applying the data to the specified IterateeGM.
