I am all FLAC

Feb 14 2008, 09:31

Hi,

I am using Linux, and I would like flac to include the version number of flac that was used to create the flac files.

I would think

CODE

flac --tag="encoded by"="flac 1.2.1" kingdom_of_heaven.wav

should do the trick, but it doesn't add anything.

Can someone help me with this?

Try this instead:

CODE

flac --tag="encoded by=flac 1.2.1" kingdom_of_heaven.wav

I've not done it myself, but IIRC FLAC files use Vorbis comments. The syntax appears to be:

CODE

vorbiscomment -a -t 'ENCODED BY=flac 1.2.1' file.ogg newfile.ogg

... in your case .flac, of course.

See here:

http://linux.about.com/library/cmd/blcmdl1_vorbiscomment.htm

EDIT: No scratch that -- doesn't work. That calls Vorbis Tools. which seems to be looking for an Ogg stream.

Sorry, can't help.

It looks to me like you want Metaflac.

If you install the Flac package with your distro's package manager you should get it.

Here are the options for using Metaflac:

I'm playing with it at the moment.

OK< so this one is quite a saga. It turns out that the syntax of some of these options has changed ... as you'll see if you type in:

CODE

metaflac --help

What you need currently is this command line:

CODE

metaflac --set-tag=ENCODEDBY=FLAC1.2.1 filename.flac

... where filename.flac is the file in question.

Alternatively you can make a little textfile with the desired blurb in it (FILE) and import from that -- like this:

CODE

metaflac --import-tags-from=FILE filename.flac

Similarly, if you wish to look at the tags, you issue this command:

CODE

metaflac --export-tags-to=FILE filename.flac

that syntax is fine and worked for me when I tried it in a bash shell:

CODE

$ flac  --tag="encoded by"="flac 1.2.1" kingdom_of_heaven.wav

The version number gets stored anyway in a metadata block, so it doesn't make much sense to use vorbis comments for this unless you include more information like the compression level used.
This is how you access this information:

CODE

metaflac --show-vendor-tag <file>

I am a bit confused about these ogg tags...

When I do the encoding like you (and all the other suggestions) did, I can not see the "Encoded by" field in EasyTag being set. Try and see screenshot at

Is that because EasyTag adds something extra to the flac file inorder to store the "encoded by"?

Btw. So you like that trailer music as well?

CODE

That's very cool

Then I can do thing like this

CODE

~/movie/trailers-movie/music/a$ metaflac --show-vendor-tag kingdom_of_heaven.flac | sed 's/reference //'
libFLAC 1.2.1 20070917
~/movie/trailers-movie/music/a$

and insert that dynamically

Afterwards can I fill out artist,title,album and so on in EasyTag
