Dump audio metadata (album title, track number, etc.) to command line

If it's a standard sort of tag, I believe exiftool should do the trick.

If it doesn't you'd likely need to find something else that dumps the format that audacity uses (apparently info tags).

You can use one of these tools:

mediainfo

Simple program outputting all the basic information from audio files.

exiftool (from package perl-image-exiftool)

This one is more customizable and supports reading and writing meta information in image, audio and video files.

mutagen-inspect (from package mutagen)

Simple frontend to the mutagen audio tagging library for Python.

Try the utility id3info for MP3 files.
