M4A tags are not exported

Post by nonenmac » Sun Jan 03, 2010 4:13 am

When I export a selection to a M4A (AAC) file (FFmpeg), the tag data that I entered into the template is not included in the exported audio file. It works for MP3 files, but not for M4A files. Am I doing something wrong, or is this a problem with the sofware?

This bug has just been fixed in the nightly builds.

http://wiki.audacityteam.org/index.php? ... tly_Builds

Note that the Windows builds linked from this page are "frequent" rather than "nightly". Make sure the About Audacity dialog shows a build date of January 2 2010 or later.

Hi.
Though this issue should have been fixed in 2010 I still encounter the same problem in 2013 on
Windows XP SP3 with
Audacity 2.0.3 (german version)
FFmpeg: F(52.64.2),C(52.72.2),U(50.15.1)
Lame: 3.99.3

Tags not exported:
Composer
Interpret
Album-Interpret
Year

Tags exported though:
Track (nr)
Genre
Title
Album
Comment

as visible to MP3Tag(v2.55a), Format Factory (Media Info), nokia mobile device and nokia suite.

Could you please recheck this, if it is a problem in audacity or FFmpeg or a typical PEBCAC? In case of the latter please let me know how to circumvent this issue, please ;-)

Audacity currently supports only these tags: http://manual.audacityteam.org/o/man/me ... ditor.html
Of these, Artist Name and Year are not currently supported for M4A format - the others are.
Audacity is an audio editing application, not a dedicated audio tagging application - for comprehensive tag support you really need to use a specialist program such as MP3Tag.
