******************************************************************
*
*  NOTE: There is excessive buffering here, BSYNZ and DEEMP should be
*        changed to operate on variable positions within SOUT.  Also,
*        the output length parameter is bogus, and PITSYN should be
*        rewritten to allow a constant frame length output
