In Logic Pro, choose File > Project Settings > Audio, then click the General button.
From the Spatial Audio pop-up menu, choose Dolby Atmos.
The Surround Format parameter automatically switches to 7.1.2, and the Frame Rate parameter in the Synchronization project settings switches to 24 fps.
If you want to change the 7.1.2 surround format for the bed tracks, click the Surround Format pop-up menu and select 5.1 or 7.1.
From the Sample Rate pop-up menu, choose 48 kHz or 96 kHz (or any other sample rate, if needed).
WARNING: Only switch the project sample rate if you haven’t recorded any audio regions in your project yet.
Pay attention to the following:
Sample rate: Don’t change the project sample rate on an existing project. If the sample rate is different from 48 kHz (required for the ADM BWF master file), Logic Pro will automatically convert the project sample rate in real time.
Surround plug-in: If you convert a surround project that already uses plug-ins on any channel strip, then the conversion might change the channel mode of the existing plug-ins, which could affect the sound of your mix.
Overhead channels: If your project surround format is set to 7.1.2 and you use the Dolby Atmos plug-in to monitor your mix in 5.1.4 or 7.1.4, any bed track signals routed to the top two channels of the surround bed (Ltm and Rtm) are balanced between the top four channels of the 5.1.4 or 7.1.4 monitoring formats (Lt, Rt and Lts, Rts).
Surround formats: Dolby Atmos projects only support three surround formats: 5.1, 7.1, and 7.1.2.
WARNING: If you create a Dolby Atmos mix from a finished stereo or surround mix, you may want to save a copy of your project or create a project alternative to avoid overwriting settings and parameters in the earlier finished mix.
