THE RINGER

Uses Demucs (Meta Research) to analyze frequency patterns and isolate vocals, bass, drums, guitar, piano, and other instruments from a mixed song. Runs locally on your Mac or via our cloud server.

No. Bandmates go to companion.theringerapp.com, enter the 6-digit code you share, and they're connected. Works on any phone, tablet, or computer with a browser. No app, no account, no same WiFi required. They can also "Add to Home Screen" for offline access between gigs.

Songs added to your setlist with just a click track — no stems or audio files needed. Set the BPM, key, and time signature manually or use the AI lookup. Great for songs you haven't separated yet, or acoustic numbers where you just need a click.

Yes! Bandmates' notes, chord charts, and lyrics are stored locally on their phone. Notes are keyed by song title + artist, so if the same song appears in a different setlist or a different session code, their notes are already there. They can prep offline between gigs — everything is ready when they reconnect.

Yes! After initial setup, stem separation runs locally. Playback, mixing, companion viewer, and live mode all work on your local network — no cloud required.

MP3, WAV, AIFF, FLAC, M4A, OGG, OPUS, WMA, and YouTube URLs (Band tier).

Yes — export any setlist as a ZIP file that includes all stems, mixer settings, and metadata. Another Mac running The Ringer can import it and have every song ready to play instantly.

Local WiFi connects bandmates directly to your Mac over the same network. It has the lowest latency and works completely offline — great for rehearsal spaces with no internet. Share Online uses our cloud API relay, so bandmates can join from any location with internet by entering a 6-digit code. Both modes sync the same data: live click, bar/beat position, song sections, lyrics, and personal notes. You can use both simultaneously — some bandmates on WiFi, others online.

Toggle "Share Online" in the Companion panel — you get a 6-digit code and QR code. Bandmates enter the code at companion.theringerapp.com from any device, anywhere. The connection goes through our cloud API relay server, so bandmates don't need to be on the same WiFi — they can be across town or across the country. The API syncs song changes, beat position, bar counts, and section markers in real time with predictive timing for zero perceived lag. Session codes persist across app restarts, and each bandmate's notes, chord charts, and lyrics are stored locally on their device and keyed by song title, so they carry over to any future session automatically.

Yes. Your songs and mixes stay on your Mac. You revert to Free tier limits.

The Ringer is available on macOS, iOS (iPhone & iPad), and Android. A Windows version is not yet available. The companion viewer works on any device with a browser — no app needed for bandmates. All stem separation runs on our cloud API, so mobile users get the same AI-powered processing as Mac users.
