Description Peter Sampson 2020-10-07 06:09:49 UTC

When exporting in M4A(AAC) format the artist name tag is not passed through as part of the metadata to the exported audio file.

This does not affect other exports such as MP3

Originally reported on Github:
https://github.com/audacity/audacity/issues/682

Occurs in 3.0.0 and 2.4.2 so does not appear to be a regression

See also Bug #1146 (re FFmpeg 2.2.2 exports)

Comment 1 Peter Sampson 2020-10-07 06:15:15 UTC

Also (as reported on Bug #1146) the Year tag is not exported with the M4A audio file

Comment 2 Peter Sampson 2020-10-07 06:28:07 UTC

Although  Bug #1146 was closed as an FFmpeg error thus WONTFIX

I have opened this so that users see the Release Note.

Fix in:

https://github.com/audacity/audacity/commit/058023f

Also, includes the related fix for import.

Tested on W10 with Audacity 3.0.0 058023f

Comment 5 Peter Sampson 2021-01-27 11:30:04 UTC

(In reply to Leland Lucius from comment #3)
Tested on macOS 11.1 Big Sur with Audacity 3.0.0 058023f

This now works fine, the Artist and Year tags are properly passed through to the M4A file on Mac and Win

Examining the commit clearly shows this is not a platform-specific fix
https://github.com/audacity/audacity/commit/058023f9781a30ad159a32374e185176602e2fcb

So as it tests OK on Win and Mac I shall close this
