I had the Wrong audio in an MP3 file (W) in Music.app with the right tags however. I opened that, and a file (C) with the Correct audio, with Amadeus Professional. I copied the great audio and pasted it rather than the mistaken one.

How might this be automated in zsh? Both switch audio from C to W with out altering tags, or switch tags from W to C, then overwrite W (mv C W).

  • exiftool cannot write to MP3 information
  • eyeD3 can each learn and write, however I do not see a easy approach for it to
    switch all tags
  • I do not know whether or not id3v2 can do it, however it’s unacceptable
    as a result of it trashes multi-byte UTF8 characters
  • A couple of totally different internet searches turned up nothing useful.
  • SE’s “related questions” did not assist both.
