DSMI/2 is a sound interface for PC compatible computers running on IBM's Operating System /2. It goes beyond the basic sound functionality offered in OS/2 via MMPM/2 and provides programmers with a variety of functions to play music and sound effects in their programs.

DSMI/2 will be most useful to multimedia applications and game developers. It is also very well suited for network audio applications, such as Internet applications.

Features
