My personal use is to have all my tonies e.g. on my cars hifi system, too:

Features

  • The script converts only new TAFs. → Already converted are skipped.
  • Full ID3v2.3 tag information parsed from latest ‘tonies.json’.

What it does?

  • Download latest ‘tonies.json’ for ID3v2.3 tag information.
  • Process all TAFs from SOURCE directory.
  • Download cover image, crop, square, resize and add boarder.
  • Parse ‘tonies.json’ for full ID3v2.3 tag information
    • Performer
    • Album
    • Track name (from tonies.json if present!)
    • TrackNr./TrackTotal
    • Disc/DiscTotal
    • Genre
    • Comment includes Model
    • Cover (front)
  • Convert to single or SPLIT mp3 file. Default is split mode.
  • Check for already converted TAFs

How to use it?

  1. Create new file and copy code.
  2. Grant file execution permissions
  3. Adjust the follwoing variables to your setup:
    SOURCE → TeddyCloud library directory, e.g. “/teddycloud/library/by/audioID/”
    TARGET → directory of your choise, e.g. “/home/user/export/”
    OPUS2TONIE → path to Opus2Tonie python script which is used to extract the AudioID from TAF
    TMP → local temp folter to process data. Will be deleted afterwards.

Prerequisites

  • jq to parse JSON data on bash
  • ffmpeg to convert TAF to mp3 and add cover
  • imagemagic to process image for perfect fit
  • Opus2Tonie must be downloaded. It requires Python3
  • Opus2Tonie requires python3-protobuf to decoce protobuf.
    please install it via pip and/or apt
