3. ADM (Audio Definition Model) Metadata
3.1. Notes
ADM metadata is used in master recordings to describe the format and content of the tracks. In practice on wave files, ADM tells a client which tracks are members of multichannel stems or “beds” and their speaker assignment, and which tracks are freely-positioned 3D objects. ADM also records the panning moves on object tracks and their content group (“Dialogue”, “Music”, “Effects” etc.)
ADM wave files created with a Dolby Rendering and Mastering Unit are a common deliverable in feature film and television production. The Dolby Atmos ADM Profile describes how the RMU translates its native Master format into ADM.
