Until now, I haven’t paid any attention to the metadata in my final audio files. I understand that Bitwig’s “Info” tab allows to enter some data that will be inserted as metadata in the exported audio file. Do you use it? Do you use something else to add more i.e. a cover?
I used MP3tag from like 20 years ago I think, but it is better to fill out meta data in project itself, if it’s available (I don’t remember having this in Ableton or anywhere else really). WAV files do have meta data, but much more limited than MP3’s and some other formats, either way I assume Bitwig will apply what’s possible when rendering.
