Convert Blu Ray Audio to FlAC - free ?

Hi,

I used to use a trail version of DVD Audio Extractor to make FLAC files from my Blu Rays.

Now,... I'm starting over actually and I may purchase DVDAE though right now all my disposable income seems tied up into UHD BD collecting.

Is there a free program to convert audio from video that does good ?... I have installed Audacity but like most people I have no idea how to use it.

I did a conversion with VLC but the quality options are all low... it can't give me 24/96 FLAC for example.

Most likely I really need DVDAE.

-Brian

Most likely you can do this with ffmpeg but you'll need to understand the command line.
It could be as simple as:
ffmpeg -i INPUT.mka OUTPUT.flac

Thanks.

Turns out I must have never used DVDAE on this laptop as I have the free trail again for 30 days. I will register it after the 30 days. That will make a good amount of time to recover from my Black Friday UHD BD purchases.

What I do is the following: -

Use: MakeMKV GUI to back-up the Blu-ray audio disc to an MKV file (complete with video, audio streams and chapters)
Use: gMKVExtractGUI v2.5.0.0 to extract the required audio stream (ie: PCM, Dolby TrueHD or DTS-HD MA) and chapter information (as a .cue file).
Use: UsEac3To to encode the extracted audio stream to FLAC

The above is an over simplification, as you will have to become familiar with the functionality of each software and install supporting softwares. Plus, not all Blu-ray audio discs offer the ability to create separate tracks (if that's your preference). Personally, I select tracks using a .cue sheet file with my OPPO.


Cheers

Would I be correct in assuming that following the process you laid out, or using the DVDAE mentioned above, would allow one to get around any region restrictions?

Yes it would. However, in the case of Blu-ray audio discs, especially HFPA Blu-ray audio discs, they are not region coded anyway.

Great. Thank you for the information. After I posted I realized I'd had a bit of a brain-fart as the particular item I'm trying to find a solution for is a concert disc (reportedly Region B) and I'd want the video, too, so audio extraction on it's own wouldn't quite cut it.
Thank you again for your response.
