DirectMusic
From Wikipedia, the free encyclopedia
DirectMusic is a component of Microsoft DirectX that provides a medium over which music and sound effects can be played back. One of its benefits is the timestamping of MIDI input data at the moment of arrival to a system wide reference clock. Music or sound effects composed for DirectMusic can be very flexible and can change dynamically over time or in response to a user event. This sound playback can be stored in relatively small files, which makes it very well suited for Web applications. DirectMusic's software synthesizer assures that MIDI files and DirectMusic segments sound identical on all hardware configurations rather than playing differently on different computers with different sound cards. DirectMusic Producer can be used to create sound files that take advantage of DirectMusic's interactive features. Rather than a static playback, this sound content can provide, if the music author chooses, a flexible and variable playback. Architecturally, DirectMusic is a high-level set of objects, built on top of DirectSound, that allow you to play sound and music without needing to get quite as low-level as DirectSound.
DirectMusic was introduced in February 1999 as part of the 6.1 version of the DirectX library. It is included in all Windows operating systems starting with Windows 98 Second Edition.
