foo_musicbrainz, MusicBrainz Tagger Options

[noiselab]

When trying to retrieve tags by TOC, the track length in samples must be divisible by 588. Can support for files encoded at 48000hz (eg Opus files) be implemented for when retrieving tags by TOC?

Does foo_musicbrainz write ID3v2.4 tags? If so, can it be changed to write ID3v2.3?

[Rarn]

I believe this plugin is writing MusicBrainz IDs to the incorrect tags. At the very least it is writing them differently than Picard, and I believe Picard is the reference standard.


The full tag mappings are here:
http://musicbrainz.org/doc/MusicBrainz_Picard/Tags/Mapping

As you can see, Picard tags Album ID in ID3v2.3 in "TXXX:MusicBrainz Album Id"
However, foo_musicbrainz tags Album ID to MUSICBRAINZ_ALBUMID

this also occurs with Artist IDs (though not Track IDs strangely)


This can be tested easily by tagging an album in foobar first with foo_musicbrainz, and then tagging the album again in Picard (make sure to not have it delete all prior tags before writing). You'll have redundant tags, with both "MUSICBRAINZ ALBUM ID" and "MUSICBRAINZ_ALBUMID" populated with the same data.

I'm not sure which is correct, but I would lean toward Picard. Regardless they should be doing the same thing.

What should I do if I want to adhere to musicbrainz standards?

i don't use this but i'm guessing it uses the foobar core to write tags. check the settings under file>preferences>advanced>tagging>mp3>id3v2 revision and quirks.

(these days foobar writes id3v2.3 by default but if you've continuously upgraded from older versions it may have remembered the old default of using 2.4)

Hey,
Does this plug-in do a fingerprint of the track? I think it should do, but I can't manage to find the option/button for this.
As it is written in the first post:

Fetches data by automatically calculated MusicBrainz Disc ID

The only musicbrainz related buttons are in RMB->Tagging->Get Tags From MusicBrainz (artist and album tags // musicbrainz album id). My understanding is that the music album id option should calculate the fingerprint and querry the server, but instead it just ask me to manually enter the ID. Is this the intended behaviour?

Just insert your cd and it will find it in MB instead of using FreeDB or CDDB for instance.

No, it doesn't. If you want full musicbrainz features, use Picard or any of the provided third party alternatives (see mb homepage).

Fetches data by automatically calculated MusicBrainz Disc ID

Yes, but only for lossless sources. You can't derive disc ID's from sources that don't preserve the 588 sample sector layout of Redbook-CDs, as do most (all?) lossy codecs.

Yes, as said above, the plugin doesn't support fingerprinting. Additionally you're misunderstanding said option. It only works if either the album ID is present already or you can provide it manually. Fingerprinting has nothing to do with album IDs, because fingerprinting can only identify tracks, not albums. It's up to the application to use a smart algorithm for clustering single tracks to albums.
