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.
