Downloadable Sounds (DLS) are standardized sound files of musical instruments, sound effects and dialogs used by musicians, composers and game developers to create soundscapes.
MIDI files with the downloadable DLS files are ideal for composers who want predictable playback or digital audio
, but at the same time want the compactness and interactivity of standard MIDI files.DLS files ensure that when played back, the same sound image
isachieved on fully-comman different audio devices. A DLS-compatible synthesizer
thus becomes an interactive device that produces the sound intended by the composer. The DLS Level 1 specifications describe the necessary synthesizer architecture required to play the DLS files. Later specifications target the more advanced functions and features and are aware of various synthesizer functions.
