//	Parameter Blocks for AudioCodec Component Routines
//
//	Note that the arguments for all the AudioCodec component routines are
//	4 bytes in size (assuming pointers are 4 bytes). This means that even on
//	Windows (where all arguments are forced into SInt32s), we can get away with
//	mass casting the argument list through the appropriate paramblock structure.
//	This gets around the fact that the component glue passes the arguments in
//	a different order depending on the platform and therefore makes writing the
//	 calling glue and the dispatcher much simpler.
