Why no Dolby TrueHD? #166

Closed Sawtaytoes closed 2 months ago

Sawtaytoes commented 2 months ago

Is the reason Cavernize doesn't support Dolby TrueHD because there's no documentation on how to do it?

My workaround is to record all the pre-out outputs from my AVR, but it'd be easier if I could do it in software since I wouldn't have to play the whole thing to record it.

As far as I'm seeing, TrueHD is also not supported in Cavern Driver from the same reason?

There is an explanation next to the Cavernize download. In short, it would require a complete low-level documentation, not just the header documentation what is available now.

There is a way to losslessly create 9.1.6 exports faster than real-time, but it costs $400 for the Dolby Reference Player.

What's this mean? I can buy this software if it helps me. Are you saying Dolby Reference Player can take a TrueHD Atmos track and also export a 16-channel WAVE file rendered for a given speaker configuration like 7.1.6?

Also, is this different from the Dolby Atmos Renderer? Or are you supposed to use both in tandem?

It looks like Cavernize is similar to Dolby Reference Player and Cavern Driver is like the Dolby Atmos Renderer. Is that correct?

Not for a given configuration, its 7.1.6 is fixed, but you can use Cavernize to reorder or rerender it. They improved this process since, look at the comments and the Quadraphonic Quad forum.

Both are based on the renderer, the Driver is like an AVR, and Cavernize is like DRP, it exports to files, so a media player with extra steps.

DRP is one implementation of an Atmos Renderer.
