ReplayGain Tagging for Audacious
I use Audacious as my primary player, under Ubuntu.
For my flac files, the ReplayGain metadata is in Vorbis Comments, and presumably that is pretty straightforward for Audacious.
For my mp3 files, I have no idea which tags Audacious can read RG metadata from. To my knowledge, mp3 files can have RG metadata in:
- the LAME header
- an APE v2 tag (the default for mp3gain)
- the ID3v2 tag (with the -s i option in mp3gain)
Does someone know:
a) From which of these three tags can Audacious read RG metadata?
b) Is one of these tags preferable (more bulletproof) over the others?
c) If there is RG metadata in more than one of these tags, which one will Audacious use? (What is the order of preference?)

Audacious knows nothing about the LAME header, but it can read Replay Gain from either an ID3v2 or APE tag. It looks for the ID3v2 tag first, so if a file has both kinds of tag, the APE tag will be ignored (including Replay Gain info). Assuming your MP3 files already have ID3v2 tags (which is likely), your best option is to use mp3gain with the "-s i" option.

Thanks very much for the helpful reply,John.
Yes, my mp3 files all have ID3v2 tags to contain the primary metadata (album track, artist, etc.).
The APE tags are added only when I apply RG through mp3gain, APE v2 is the default for mp3gain.
Since you are saying Audacious will completely ignore these tags, even if there is no RG info in the ID3 tag, I will need to copy the RG data from the APE tags into the ID3 tags.
Then, as you suggested, I can use mp3gain -s i to add RG tags into ID3 from here going forward.
For my flac files, I presume that Audacious will read the RG values from the Vorbis Comments.
Again, thanks for your help!

It looks for the ID3v2 tag first, so if a file has both kinds of tag, the APE tag will be ignored (including Replay Gain info).
Can you confirm that this has been improved since 7 years ago? AFAICT, the replay gain info in the APEv3 is read even when an ID3v2 tag without replay gain info is present.
