I need to compare film scenes mixed for Dolby Atmos with the same scenes mixed in a legacy channel-based surround sound format. Other than the surround sound format being different, both mixes should be identical. Is it possible to downmix multitracks mixed for Dolby Atmos to a legacy channel-based surround sound format using the Dolby Atmos Production Suite?
Yes, this feature is called "ReRendering".
In the Production Suite go to Windows --> ReRender. Here you can select what formats you need (per default 5.1, 7.1 and 2.0 are configured).
ReRenders can be routed to outputs to record them in realtime. Or you can export ReRenders offline as WAV-Files, if you go to File --> Export --> ReRenders.
Best regards, David
Can you ReRender to 7.1 if the Dolby Atmos master file has been encoded in Dolby TrueHD?
