Downmixing to a Legacy Channel-Based Surround Sound Format

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?  

Hello Scott!

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? 

Hello Scott! Dolby TrueHD is the encoded Bitstream that goes to Blu-Ray disks. You can’t load a TrueHD encode into the production suite. You would need to have the source Atmos Master File (format DAMF or ADM.wav), load this file into the production suite and create the ReRender from there (in real-time or offline, as described above). Best, David
