Spatial Audio (with Dolby Atmos): Creates a spatial audio mix in Logic Pro.
Note: To use the Spatial Audio Monitoring plug-in, you must have macOS Monterey 12.3 or later installed.
Down Mixer plug-in: Lets you hear your surround mix in stereo and other surround formats. It is not available for surround formats that use overhead channels. For more information, see Create a Dolby Atmos project.
The Dolby Atmos plug-in on the surround master channel strip renders the audio and automation metadata for each object track plus the audio from the surround bed and lets you monitor it in various surround formats up to 7.1.4. In addition to mixing on a speaker system, you can also monitor your mix in different binaural formats with just a pair of headphones. See PDF
