/*! \class SingWave
    \brief STK "singing" looped soundfile class.

    This class contains all that is needed to make
    a pitched musical sound, like a simple voice
    or violin.  In general, it will not be used
    alone because of munchkinification effects
    from pitch shifting.  It will be used as an
    excitation source for other instruments.

    by Perry R. Cook and Gary P. Scavone, 1995 - 2005.
