    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.
