Release Sonar

Welcome to Release Sonar

Hi, I am Echo

Release Sonar tells you when the artists in your music collection put out something new. No account, no sign-up: everything stays in your browser.

Never miss a new album again

Release Sonar reads the names of the folders in your music library, finds your artists in MusicBrainz and tells you when they release something new. Nothing is uploaded: it all happens in your browser.

Scan my music

It loads a real music collection, so you can see how it works. Importing yours later replaces it.

Only folder and file names are read, never your files. Your library stays on this device.

How it works

  1. Pick your music folder, paste a tree listing or type a few artists.
  2. We match each folder with an artist in MusicBrainz. You check the doubtful ones.
  3. Come back whenever you like: we show you what came out since your last visit.
