Export ADM BWF files in Logic Pro for Mac

When finish your Dolby Atmos mix, you can export your project or a section of your project to a file that uses the Audio Definition Model Broadcast Wave Format (ADM BWF). The ADM BWF master file is the required file type when you submit a Dolby Atmos mix to a mastering engineer or streaming service. ADM BWF files are also compatible with industry tools that are used to edit and master Dolby Atmos mixes for further distribution.

WARNING: An ADM BWF is a multichannel interleaved WAVE file that you could play back like a standard wave file; however, you would only hear the first two channels of the bed tracks.

Export a Dolby Atmos mix to an ADM BWF file

  • In Logic Pro for Mac, go to File > Export, then choose one of the following options from the menu:

    • Project as ADM BWF: Exports your entire project. It starts at the beginning of the project and stops at the end of the last region, including any effect tails, such as reverb or delay.

      Note: To match the length of the Dolby Atmos mix to the stereo mix, use the export option Selection as ADM BWF.

    • Selection as ADM BWF: Exports a selection of your project.

      When you choose Selection as ADM BWF, Logic Pro exports the part of your project enclosed by the cycle area or a marquee selection. You can also select a group of regions to define the start point as the beginning of the first selected region and the end point as the end of the last selected region.

Note: The selected monitoring format in the Dolby Atmos plug-in has no effect on the ADM BWF export.

ADM BWF files exported by Logic Pro contain the following:

  • All the audio channels containing the surround bed and the individual mono and split stereo object tracks.

  • The pan automation data of all object tracks. See 3D Object Panner parameters.

  • Metadata (including downmix and trim settings) required to reproduce the mix on systems or devices compatible with Dolby Atmos. For details, see Downmix and trim controls.
