Extract DTS-MA from MKV in highest quality (FLAC or PCM)

[x8009]

Hi,

I have MKV movies that are HDR 4K with True DTS or DTS-MA and I want to rip only the sound, some of them have communitaries which I also want to remove.

How can I do it ? I want to have the original Audio track 24bit 48000 True-DTS and be able to move forward or backward while it's playback. Cause I made it to get the file as THD file, but I can't find a way to edit it before or after and I can't move forward or backward , it just play it back from start to end, can only pause.

I took the programs from the thread here . Hybrid works fine but it keeps the communiatries audios also , and there is no way to edit in the program or at least from what I tried .

Perhaps ffmpeg?

Bellow script for Windows, Unix script should be not different.

@setlocal
@set nme=%~1
@ffmpeg.exe -v 32 -stats -y -hide_banner -i "%nme%" -vn -c:a flac -compression_level 12 "%~n1_.flac"
@endlocal

Hi , thanks

ok I wrote it like you said without the @set .

I am getting this thing

Is this correct ? because it's so slow speed , I have AMD TR4 16 Core, I don't understand why it's so slow .. in the end I'll have FLAC file that I can move forward and backward ? Is there a way just to extract Dolby Atmos-TrueHD Audio and not to convert anything and just playback like it's normal file ?

thanks


* Is it possible to keep the ATMOS TRUE HD and to be able to playback with forward and backward ? and also so I would be able to edit it to cut the parts I don't wants ? because I would like to keep all the 3D detail the ATMOS is giving .. I don't think flac will keep that information right ?

EDIT : Ok I've managed to do it with Hybrid ... I needed to change some settings that I did not do before, now I have only the ATMOS TRUE HD AUDIO which is 3.5 GB , I can forward and backward .
