/*! \class VoicDrum
    \brief STK vocal drum sample player class.

    This class implements a drum sampling synthesizer using FileWvIn
    objects and one-pole filters.  The drum rawwave files are sampled
    at 22050 Hz, but will be appropriately interpolated for other
    sample rates.  You can specify the maximum polyphony (maximum
    number of simultaneous voices) in VoicDrum.h.
