Hello everyone,

I've read about core audio and I'm very lost.

I have a video which have
DTS-HD MA Surround 5.1 English
- DTS Surround 5.1 English - Flag Core Audio

Once extracted, the MKV file have 2 audio track. My understanding is that it should only have 1 track? Do I need to check both of them or will I go missing part of audio if I don't check the core audio? I have this with either 5.1/7.1 audio with 5.1 core with DTS and Dolby. I'm unsure what I'm suppose to select to have the whole soundtrack when playback. I do have a 7.1 home theater.

Thank you

For some codecs, like DTS-HD MA, MakeMKV will create a second track with just the lossy core audio in it, for compatibility purposes.

Ok, so it is not needed if I want only the full DTS-HD or TrueHD Atmos track?

Correct. The way they work is you have the lossy core, and additional data to replace the "lost bits". Players that don't support the loss-less playback ignore that data. In Theory.

Not all players handle that well. If your player does, there is no need to keep the separate track.

Oh great, I'm playing everything through my computer that support anything I throw at him so no problem.

Thanks
