DiamondWare Digitized

Latest revision as of 04:08, 28 December 2023

DiamondWare Sound Toolkit^[1] was an SDK for the creation of sound files used in games in the early 1990's by Keith Weiner & Erik Lorenzen^[2]. Sold through MVP Software.

[edit] Format Information

DWD (sounds) & DWM (music) are propriety formats for Diamondware's SDK^[3][4]. They seem to be derived from VOC and MIDI^[5].

• DWD files begin with the ascii DiamondWare Digitized
• DWM files begin with the ascii DiamondWare Music
