Guides to identifying and renaming audio files

Songs lose their names on the way from one device to another. These guides cover how to get them back, starting with the methods that cost nothing.

• How to identify a song from an audio file

  Three ways to find out what song a file is: read the tags inside it, play it to a listening app, or fingerprint the file itself. What each costs and what none of them can name.

• How to batch rename music files to Artist – Title

  Renaming a whole folder at once: from the tags when the files have them, and what to do when the tags are empty. Naming patterns, and what to check before you start.

• What song is AUD-…-WA0031.opus?

  Why songs sent through a chat app arrive named after a date and a counter, where those files are kept on a phone, and how to give each one its real name.

• Mp3tag vs MusicBrainz Picard vs Track ID Deck

  Three tools that fix badly named music in different ways. What each is best at, where the other two beat ours, and how to use them together.
