In the Trim and Downmix Settings for Dolby Atmos, the downmix settings for 5.1 and 2.0 are combined. Why? Is this a Dolby Atmos thing or a Nuendo thing? Is there a workaround, such as editing the metadata manually? How might I do this?
I ask because my music projects are mixed for 5.1 surround already, so the Dolby Atmos downmix settings for 5.1 are ideally -0 dB (no change) in all channels. But that’s not ideal for the 2.0 downmix, which typically requires -3 dB in the Surround channels, give or take.
Furthermore, I have stereo downmixes that are purpose-built for 2.0 and will sound better than any set-and-forget algorithmic downmix. Is there any way to leverage these in my Atmos deliverables?
Any advice is appreciated.
