I’m really surprised by this. It must be an oversight or a bug.
I’d seen at the Audirvana community pages people were finding that Audirvana was analysing files and inserting a MusicBrainz metadata tag. There does not seem to be any official comment on this yet.
Affecting LAN bandwidth by analysing and modifying files on a NAS without requesting permission to do so.
Altering thousands of files which if you have an automatic backup strategy could trigger software to detect modifications and backup the new altered files replacing your originals. Potentially a very time consuming process too.
Crashes - it crashed several times, I’d have to wonder if this happened during a write to add a MusicBrainz metadata tag if the original file could become corrupted.
It will take ages to work out what has been changed where!
I feel sorry for the Audirvana team but this is bad.
