      Do you distribute Dolby Atmos releases?

      Yes, we do!

      Dolby Atmos must meet the following requirements:

      • Dolby Atmos audio files generated from stereo mixes are not allowed. Specifically:

        • A Dolby Atmos track must be created from multitracks or stems created from multitracks.

        • Upmixing from a stereo release is not allowed.

        • Extracting stems (“de-mixing”) from a stereo release is not allowed.

        • A Dolby Atmos track consisting only of a stereo mix placed in the sound field with added ambience or reverb is not allowed.

      • Provide the Dolby Atmos file as a Broadcast Wave Format Audio Definition Model (BWF ADM) file.

      • All tracks within a project must be at the same frame rate.

      • All audio must be 24-bit linear pulse code modulation (LPCM) audio at 48kHz.

      • You must conform and sync the Atmos files with the stereo reference files for the same project.

      • The integrated loudness value should not exceed -18 LKFS measured as per ITU-R BS. 1770-4.

      • True-peak level should not exceed -1 dB TP measured as per ITU-R BS. 1770-4.

      • Full-frequency content should not be present in the Low-Frequency Effects (LFE) channel of the BWF ADM.

      • For albums where gapless playback is intended between tracks:

        • Each album track must be delivered as an individual BWF ADM file.

        • Each track boundary must be no more than half a frame (1,000 samples @ 48 kHz) earlier or later than the same track boundary in the corresponding stereo deliverable.

        • There must be no additional silence at the end of each track when compared to the same track from the corresponding stereo deliverable.

       

      Process to follow:

      1. Assign a UPC and ISRCs to the stereo version of your release.
      2.  Assign a different UPC and different ISRCs to the Atmos version of your release.

      • All other metadata for the stereo and Atmos versions must be identical.
      3. Import both the stereo and Atmos releases at CI, following the standard import process.
      • Use the same artwork file for both the stereo and Atmos releases.

      Inform distribution@musicgateway.com about the import, asking us to link the two releases together.

      If your Dolby Atmos release is new, and there is no standard stereo version of the audio, the process is much simpler: You can just import the Dolby Atmos release, and email us asking to export the Dolby format to Apple Music.

      The Apple system will automatically “downmix” the Atmos audio to stereo for those consumers who wish to listen in the stereo format.
