Can I add ISRC codes to metadata?

I’d like to use Audacity to edit the metadata genre if my .wav files. If I do so, will it overwrite (or clear out) the ISRC codes? I don’t want to remove ISRCs.

I am using Windows 10 and Audacity v. 2.1.2

Thank you in advance.

Probably… Do you see the ISRC code in the metadata editor? You can try it… When you export from Audacity it creates a new file so you’re not directly editing an existing file. Certain tags are not copied-over to the new file. Audacity doesn’t keep embedded artwork, some people have trouble with various tag formats.

A regular tag editor like MP3tag should work because it only edits the tags you change and it doesn’t re-write/re-create the whole file. (MP3Tag works on most formats, not just MP3/ID3.)
