How to write Album Artist ID3 tag using lame?

Lame does have ID tags in commandline form. Use them when you are encoding with lame. To tag existing files you may be better served using another method. Refer to the man page by running man lame or even lame -? provides good info.

lame -?

  ID3 tag options:
--tt <title>    audio/song title (max 30 chars for version 1 tag)
--ta <artist>   audio/song artist (max 30 chars for version 1 tag)
--tl <album>    audio/song album (max 30 chars for version 1 tag)
--ty <year>     audio/song year of issue (1 to 9999)
--tc <comment>  user-defined text (max 30 chars for v1 tag, 28 for v1.1)
--tn <track[/total]>   audio/song track number and (optionally) the total
                       number of tracks on the original recording. (track
                       and total each 1 to 255. just the track number
                       creates v1.1 tag, providing a total forces v2.0).
--tg <genre>    audio/song genre (name or number in list)
--ti <file>     audio/song albumArt (jpeg/png/gif file, v2.3 tag)
--tv <id=value> user-defined frame specified by id and value (v2.3 tag)
--add-id3v2     force addition of version 2 tag
--id3v1-only    add only a version 1 tag
--id3v2-only    add only a version 2 tag
--id3v2-utf16   add following options in unicode text encoding
--id3v2-latin1  add following options in latin-1 text encoding
--space-id3v1   pad version 1 tag with spaces instead of nulls
--pad-id3v2     same as '--pad-id3v2-size 128'
--pad-id3v2-size <value> adds version 2 tag, pad with extra <value> bytes
--genre-list    print alphabetically sorted ID3 genre list and exit
--ignore-tag-errors  ignore errors in values passed for tags

Note: A version 2 tag will NOT be added unless one of the input fields
won't fit in a version 1 tag (e.g. the title string is longer than 30
characters), or the '--add-id3v2' or '--id3v2-only' options are used,
or output is redirected to stdout.

Use it like this from a script I run:

        lame  --vbr-new --preset standard --tt "${tt}" --ta "${ta}" --tl "${tl}" --ty "${ty}" --tn "${tn}" --tg "${tg}" --add-id3v2 infile.wav outfile.mp3

Album artist is a non standardized ID3 tag. A lot of popular music players, like iTunes and Windows Media Player, understand the the TPE2 as the album artist.

So you must use something like:

--tv TPE2=%albumartist%
