    longDescription = ''
      wavrsocvt is a command-line utility which can be used from a
      terminal window or script to convert .wav files into sound
      files for the NXT brick (.rso files). It can also convert the
      other direction (i.e., .rso -> .wav). It can produce RSO files
      with a sample rate between 2000 and 16000 (the min/max range of
      supported sample rates in the standard NXT firmware).
      You can then upload these with e.g. nxt-python.
