DLS
The MMA’s Downloadable Sounds (DLS) Specification defines a sound data format and the required synthesizer features for accurate playback on any DLS compatible synth.
DLS LEVEL 1
This document and the underlying specification is the result of extensive research and discussion by a group of hardware and software manufacturers to determine a base-line architecture which will support playback of “downloadable” sounds.
DLS LEVEL 2
The MMA’s Downloadable Sounds Specification Level 2 (DLS-2) is a logical extension of DLS-1 intended to be in-line with what is commonly considered state of the art today in multimedia computing.
