Convert ATMOS and DTS:X to FLAC
As a bonus I would like to check how good new object-based codecs Dolby Atmos and DTS:X compressed. In new codecs sounds are encoded as objects, that coming from a certain position, rather than from where the speakers are supposed to be. And then the reciever mixes the audio to make it sound like it's coming from that position.
Dolby Atmos and DTS:X Logos
Be aware that Dolby Atmos is an extension to TrueHD and DTS:X - is an extension to DTS-HD MA. Those extensions metadata will be ignored or stripped out during conversion, because its not comparable to any audio codec yet. So only DTS-HD MA and TrueHD part will be recompressed.
I have only a few movies with object-based soundtracks so averages will not be so fair.

Even object oriented HD-audio is the future of cinematic sound, DTS-HD MA still truly leads among other codecs on the Blu-ray market.
