Based on the Pink Trombone algorithm by Neil Thapen, Voc implements a physical model of the vocal tract glottal pulse wave. The tract model is based on the classic Kelly-Lochbaumsegmented cylindrical 1d waveguide model, and the glottal pulse wave is aLF glottal pulse model.  The soundpipe source code for Voc is generated via ctangle, one half of theliterate documentation system known CWEB. The CWEB are maintained in a separate repository. They are hosted on github here: http://www.github.com/paulbatchelor/voc This documentation is a stub.
