Applying Metadata via Command Line

Is there a command line way of applying the metadata stored in a template to wav, mp3 and flac files. Preferably without launching the gui.

Thanks

There’s an app for that … https://en.wikipedia.org/wiki/Tag_editor#Audio_files

Which, if any of those, applies the metadata stored in a (Audacity) template?

Those tag editors are stand-alone software, (independent of Audacity).
They are for batch-processing the metadata in audio files, (which I though was your brief).

Command line script batch processing yes. But using existing Audacity metatdata template file as data source.
