Dolby Atmos is a proprietary technology and cannot be created outside of Dolby hardware and software.

All audio must be 24-bit LPCM audio (.wav file) at 48kHz.
- Dolby Atmos files must conform and be synced to the original stereo master files

True-peak level should not exceed -1 dB TP measured as per ITU-R BS. 1770-4.
- The difference in duration between the Dolby Atmos file and it's corresponding Stereo file must be less than or equal to 50 milliseconds
