VDMSound is a program that overcomes what has probably been the most exasperating limitation of DOS boxes since Windows NT -- sound support. VDMSound is an open, plug-in oriented platform that emulates an MPU-401 interface (for outputting high-quality MIDI music), a SoundBlaster compatible (SB16, SBPro 2, SB2, SBPro, etc.) "DSP" implementation (for digital sound effects and other PCM audio), as well as a standard game-port interface (for playing games with joystick support). In development are AdLib support (for FM-synthesis music), advanced joystick support, and possibly VESA support. VDMSound works on Windows NT 4.0, Windows 2000 and Windows XP.
