v2.1.0

2024-06-09 – v2.1.0

• Prepare for third-party pre-processing software:
  • A JSON file (or stdin) can now be used to set or override any of the
    known tags (see help). Values from JSON override values read from the
    audio file’s tags.
  • This can be used, for example, to set values from a database (like
    AzuraCast’s cue and fade data from their Visual Cue Editor).
  • cue_file might still decide a re-analysis being necessary, so it’s
    wise to re-consolidate the data after cue_file has returned its results.
• More robust variable reading from tags or JSON:
  • Booleans can be bool or string
  • Typechecking on tags with unit suffixes, especially liq_true_peak,
    which was a "dbFS"-suffixed string in v1.2.3 and now is a linear float.
• Added liq_fade_in & liq_fade_out to known tags. We don’t use these,
  but pre-processors might want to set them.
• More advance example in test_autocue.cue_file.liq that shows how
  annotations can be used to play 15-second snippets of songs.
