I would like to show you my new version of tone [1], a command line audio tagger. It is mainly developed for audiobooks, but should also work for music and other formats. Features:

- dump metadata in different formats with JSONPath support

  tone dump my-file.m4b
  tone dump --format=json --query='$.meta.album' my-file.m4b

  tone tag input.mp3 --meta-title "a title"
  tone tag --auto-import=covers --auto-import=chapters --path-pattern="audiobooks/%g/%a/%s/%p - %n.m4b" --path-pattern="audiobooks/%g/%a/%z/%n.m4b" audiobooks/ --dry-run

  tone tag "harry-potter-1.m4b" --taggers="musicbrainz" --script="musicbrainz.js" --script-tagger-parameter="e2310769-2e68-462f-b54f-25ac8e3f1a21"

  docker pull sandreas/tone:v0.0.8
