+synopsis: A library to read, write and manipulate MIDI, WAVE, and SoundFont2 files.
 description:
   The library provides functions to read, write and manipulate MIDI, WAVE and SoundFont2 multimedia files. It is written entirely in Haskell (without any FFI). It uses efficient parsing and building combinators for binary data stored in ByteStrings (based on the one in 'binary' package).
   .
-  Correctness of significant parts of library has been validated with QuickCheck and Haskell Program Coverage (HPC) tool-kit.
