Channel labels for Dolby Atmos in IMF PCM audio track files

Some of the channel locations used by Dolby Atmos are not yet part of a SMPTE standard. If you are using a PCM Audio Track File to deliver channel-based Dolby Atmos in the IMF, you need to identify the assignment of each channel according to SMPTE ST 2067-2. To achieve this you must use the definitions in ‘Additional Audio Channels and Soundfields for Immersive Audio’.

Software developers can use these definitions in their software and users can reference the document when requesting this support be added.
