I remember this was asked in the past but I'm not sure where at this point, will FLAC ever support 8+ channels? I am asking for the ATMOS audio tracks, are the extra channels over 7.1 different channels or just extra information from these channels? Thanks.

I think the limit is 8, however for practical purposes, I think if you wanted to encode some ridiculous number of channels you'd probably just encode them as independent channel pairs inside a container.

@NetRanger thanks for the updated build, the two dates mean the build has all the updates up to 2017-12-04 or 2018-01-14?

Is there a way you can compile a build with the last two fixes as well, from 6 and 8 days ago? Thanks.

They're included. Have a look here
https://github.com/xiph/flac/commits/master

Seems like that dates is different on Github & Xiph.org's flac.git. I took the dates from Github flac.git

Im using media-autobuild_suite for my compilation needs. Will have a look 2morrow to see what repository the script uses to get the source from.

Perfect, thank you, damn me that I never learned how to program or follow coding stuff.

Hi all

Sorry to butt in with a simple question...  How important is it to update to the latest version of FLAC?  When I rip CDs, I still rip to version 1.2.1.  What's the downside to this?  Should I look to change it and keep up with the times or am I ok as I am?  If changing, what will the benefits be?  And should I be thinking about changing my existing FLACs to a more recent version (if that's even possible)?

Cheers

The effect on the resulting files will not be very big. There is no difference to audio quality as all FLAC files made by any FLAC version are lossless. One thing you might see is a difference in size, files encoded with newer version could be slightly smaller as modern FLAC encoders are slightly more efficient. Encoding with newer versions is faster too.

If you are on Windows I would say there is a good reason to update as there are two security issue with FLAC encoders older than 1.3.1 (CVE-2014-9028 and CVE-2014-8962 if you're interested in that sort of stuff).

As for your last question, there is no real reason to encode your existing FLAC files to a new version. It would be a lot of hassle and time while at best you would regain a few percent in storage space.

In short, yes to updating your FLAC encoder to the latest version, no to re-encoding your existing FLAC music files.

Re-encoding is possible and should be lossless. But beware that the FLAC frontend, which is a tool that I guess people would employ, has eaten several of my files even if I asked it to verify. My paranoia and my backup drive saved those, though.
Also, I do unfortunately have a couple of corrupted FLAC files. Re-encoding produces a "technically valid" FLAC file "with the corrupted content", and I do not want them to show up as OK, so I did not re-encode those.

That were the caveats I think.

As for "benefits", my reason was cosmetic: when highlighting a bunch of files in my media player (foobar2000), it would show as "Tool" a bunch of different "reference libFLAC" versions before and in between the lossies, which made that view harder to read. I did of course not transcode the lossies, but I could and did get all the different "reference libFLAC" versions (from 1.1.4 and up) down to a single one.
Saving space? Likely not enough to bother. Unless you encoded at say "-0" (some do, often by misunderstanding encoding speed vs decoding speed), or had a habit of embedding enormous picture files, which you later have deleted (I do not think many applications can "reclaim" such wasted space?) or your hard drive is so full that you really want to squeeze out that last drop.
