Detailed Description

Voice control.

Originally D:\rnd\prj\ix\win95\dsp\dspv.cpp, address range 4467a0-446f73: compiler-generated initializers, then the voice-control functions. The separately assembled sample mixer, dspmix.asm, follows.

Built /Od like the rest of ix: a full EBP frame, EBX, ESI and EDI saved whether used or not, and one shared epilogue.
