Show HN: Tone 0.1.8 – hackable cross platform audio tagger

Today I released tone 0.1.8 [1] - the new version of my hackable cross platform command line audio tagger.

  Features:
  - dump and modify metadata for most common audio formats (mp3, m4a, flac, ape, etc.)
  - use JSONPath to query single metadata fields in dumps (--query='$.meta.album')
  - common AND custom metadata fields (album, artist, but also sort-title, movement-name, etc.)
  - Chapter support for mp3 and m4a
  - Embeddable pictures
  - Custom `tone.json` metadata format to export / import all metadata in one file (including covers as base64)
  - Hackable via custom JavaScript functions (write your own taggers with url fetching and custom parameters)[2]
  - dump range of raw audiodata bytes (e.g. to calculate hashes)

Examples:

  # dump metadata for input.mp3 with json query
  tone dump "input.mp3" --format json --query "$.meta.album"

  # dump all files in audio-directory/, but only album and artist
  tone dump audio-directory/ --include-extension mp3 --format ffmetadata --include-property album --include-property artist

  # change title tag
  tone tag input.mp3 --meta-title "a title"
  
  # change tags of an audio book directory based on directory names
  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

I know not many people are tagging their audio files these days, but hey, it's a pet project, so feedback is very welcome.
