Yes, very satisfied! When it does WAVs, I'll be twice (maybe 3X) as satisfied as I am today.
Each Audacity album project includes a Label track. There, I label each album cut with its Title, Artist, Genre, Year, etc. (All my extra tag work is due to the fact that these albums include cuts from various artists, genres and years, as opposed to the usual album by one artist, in one genre, produced in one year.) Then, once the entire album is finished, I use Audacity's 'Export Multiple...' command to create the individual files, twice (once for WAVs, again for MP3s).
During Export Multiple, the metadata editor window appears once for each file to be exported; this is Audacity providing the (only) opportunity to edit tag data for each individual file being exported. If every cut on an album has the same Artist, Genre and Year, no work is needed here; Audacity automatically populates each file's Title tag with its string from the Label track and gets all of the other tags (Artist, Genre, Year, Comment) from the project's metadata. However, in my case, since cuts have varying Artists, Genres, Years, etc., this is when I get to parse the Label string and move the values other than Title into their respective tag fields. Since the typical album has ~100 songs, I do this ~100 times during the WAV export only.
But, thanks to MP3Tag and my Excel macro which parses and processes the exported Label track from Audacity, all I need to do during the MP3 export is click OK.
I don't understand why it would be better to ask for this to be done by Audacity. If Audacity has any capability for tagging any files by reading a CSV file and batch-process editing the tags in those files, I'm unaware of it. But, since MP3Tag already does all of that for MP3 files (as well as AAC, APE, APL, ASF, FLAC, FLC, MP+, MP1, MP2, MP4, M4A, M4B, MPC, OGG, OGA, OFR, OFS, SPX, TAK, TTA, WMA, and WV files!), I think it's only logical to ask MP3Tag for WAV file support, as well.
The only reason I mentioned Audacity at all is because, although I know nothing about tagging WAV files, I do know Audacity tags a WAV file in such a way that Nero Burning ROM is able to make sense of it. And, in the end, that's what I need: WAV files with tags to be read by Nero for burning Audio CDs with CD Text.
Thanks. Good to know I'm not the only one pining for this feature. (My searching the MP3Tag forums for 'wav' turned up nothing; must be one of those 3-characters-is-not-enough-but-I'm-not-going-to-tell-you-that things.) Regardless, I'll be happy to donate $50 to the cause when MP3Tag can do what I'm asking for.
)! If MP3Tag could also do this with my WAV files, I would gladly donate again.
