Metadata: When exporting to FLAC the "Comment" field is ignored and not exported with the audio file

When exporting to FLAC the "Comment" metadata field is ignored and not exported with the audio file. Reported by a user on the Forum: https://forum.audacityteam.org/viewtopic.php?f=47&t=106892&p=377461 Tested on W10 and Mac Mojave fails on both - so assume All platforms. This is inconsistent with other file type exports (e.g. MP3 where the Comment tag is properly exported)
Fix in: https://github.com/audacity/audacity/commit/81da0ef Note that some applications use COMMENT and some use DESCRIPTION to represent the comment. We were using COMMENTS. We are now using COMMENT.
Created attachment 1056 [details] still no Comments tag Testing on W10 with Audacity 3.0.0 4e6e3c2 Although I get all the other Metadata I set - I still don't see the Comments field coming through - see attachment

Other things like Foobar use one called "COMMENT". We were using "COMMENTS" which was just wrong. So, who do we make happy? We could actually write both COMMENT and DESCRIPTION if we don't want to have to settle for one or the other.
Appears that Ubuntu file properties also uses "COMMENT".
I've update it to store both COMMENT and DESCRIPTION: https://github.com/audacity/audacity/commit/37a7583 And I've modified Import to use the COMMENT value if both are present.
Created attachment 1057 [details] No comment - and year is wrong Tested on W10 with Audacity 3.0.0 4b07fba 1) I still see no comment in the FLAC file (see red-ring in attachment) 2) The "Year" that I enter in that Audacity Metadata editor is attached to "Date released" rather than "Year" in the FLAC's metadata (see blue-ring in attachment).
Created attachment 1059 [details] Metadata before Here's what I have specified for metadata.
Created attachment 1060 [details] Properties after Here's what Windows shows.
Comment on attachment 1059 [details] Metadata before Ignore this
Comment on attachment 1060 [details] Properties after Ignore this
Somewhere along the line I lost the code changes that I thought I'd committed. Redoing it now. But, I can explain the Year problem. If you specify just a year, like "1999", Windows will populate the "Year" and "Date released" property. If you specify anything in addition to just the year, Windows displays it in the "Date released" property only. After all, it's not just the year anymore. :-) This is all Windows and nothing we can do about it.
One more try (stoopid Leland!): https://github.com/audacity/audacity/commit/a2cee50
(In reply to Leland Lucius from comment #12) Audacity 3.0.0 a2cee50 Tested on W10 with Audacity 3.0.0 a2cee50 This now works fine a) the comment is passed through into the FLAC file's metadata b) the "2021" year propagates to "Year" and "Date released" - whuch is fine by me >(stoopid Leland!) Nah... very clever Leland, looks to be well-fixed
(In reply to Leland Lucius from comment #12) Audacity 3.0.0 a2cee50 Tested on macOS 11.1 Big Sur with Audacity 3.0.0 a2cee50 This now works fine a) the comment is passed through into the FLAC file's metadata into the "Comment" field b) the "2021" year propagates to "Recorded date" - which is fine by me
Examining the two commits that related to this fix https://github.com/audacity/audacity/commit/a2cee50c0146dd1e842d7e65876f1b276502de90 https://github.com/audacity/audacity/commit/81da0ef1f7c37fe35d1e5591779b219f54a52983 shows that this fix is not platform-dependent or platform-specific, therefore as this tests OK on Win and Mac I shall mark this as FIXED
