      The Transcribe! application is an assistant for people who want
      to work out a piece of music from a recording, in order to write
      it out, or play it themselves, or both. It doesn't do the
      transcribing for you, but it is essentially a specialised player
      program which is optimised for the purpose of transcription. It
      has many transcription-specific features not found on
      conventional music players.
