Extract audio from mkv

[tun.tin]

Hi all,

Please help me how to extract all the audios from the mkv files. (in batch file)
For example c:\mkv folder:
Test1.mkv (track 0: video, track 1: audio aac, track 2: dts, track 3: subtitle)
Test2.mkv (track 0: video, track 1: audio mp3, track 2: subtitle)
Test3.mkv (track 0: video, track 1: audio ac3, track 2: flac, track 3: wav, track:3 subtitle)

output will be:
Test1.aac
Test1.dts
Test2.mp3
Test3.ac3
Test2.flac
Test3.wav

Thanks

Tried mkvcleaver?

Or do you want to write your own mkvextract command line? I don't think it will be that simple to batch convert.

Yes, MKVCleaver should do what you want. Once you've opened a bunch of MKVs, use the right pane to select any audio tracks being displayed (the right pane is for batch concerting). It may name the tracks a little differently by default, such as including the track number, but that's a good thing. If you had an MKV called Test1.mkv containing two AC3 streams, they can't both be extracted as Test1.ac3, so instead they might be named Test1 01.ac3 and Test1 02.ac3 or something similar.

The latest MKVCleaver includes some custom file naming options and you can stop it from ensuring extracted file names will be unique by using it, but it's not a good idea (the custom file naming option is a good idea, just not using it to stop MKVCleaver creating unique file names).

The problem is I have mkv files in sub directories
i.e c:\mkv\test1\test1.mkv
c:\mkv\test2\test2.mkv
c:\mkv\test3\test3.mkv
.........
many more
manual select each one is a pain. Thank you.

I don't think you will find anything that support subfolders....making a custom script would be very complex.
