Writing ID3 tags to Microsoft WAVE files

I’ve noticed that Audacity is able to write only a limited set of metadata tags to WAV files, no custom fields allowed.

The availabile tags are: TITLE, ARTIST, YEAR, COMMENT.

I’ve performed the same experiment with AIFF and I noticed it has ID3 tags in it, with all tags I wrote present in it including custom, non-standard fields.

I’ve read that writing ID3 tags to WAV is possible, however a limited set of programs can do that. I wonder what can read such files, and if it’s not a playback compatibility issue.

Do you think addding an option to write ID3 tags to WAV at export in Audacity would be a good idea?

PS: My secondary question is: if I have a WAV file with tags (doesn’t matter if they are ID3 or not) is it a BWF file?
I’ve read in several places that originall microsoftw WAVE format doesn’t support any metadata. So am I actually using BWF files even though they are not explicitly named this way, nor I can’t see any binary clue in such a file (excluding the metadata block) using Hex Dump.

Audacity already does write ID3 (and LIST INFO) tags to WAV. Please read http://wiki.audacityteam.org/wiki/WAV#Metadata .

To take advantage of the features listed there, please download the current Audacity version from http://audacityteam.org/download/.

No, because it does not have the extra chunks specific to BWF. See http://en.wikipedia.org/wiki/Broadcast_Wave_Format.
