 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.
