Sound Manager

The Sound Manager is a collection of routines that native or third-party applications use to create sound without a knowledge of or dependence on the actual sound-producing hardware available on any particular Macintosh computer, prior to OS X. More generally, the Sound Manager is responsible for managing all sound production on Macintosh computers. Other parts of the Macintosh system software that need to create or modify sounds use the Sound Manager to do so. Sound Manager was first introduced in the Macintosh system software version 6.0 and was significantly enhanced since that time through Mac OS 9.x. Prior to Mac OS 6.0, applications could create sounds using the Sound Driver (how’s that for some Mac trivia?).
