MonoBand: AI Stem Splitter

New: a tempo-synced metronome, count-in for recording, and a full chord chart with a live progress bar. Separate stems, mix, sing & play along — up to 10 tracks.

MonoBand turns any song you own into a full practice and remix studio — right on your iPhone and iPad, with no internet and no subscription.

Using an on-device AI model (HT-Demucs) running on Apple silicon, MonoBand separates a track into 6 independent instruments — vocals, drums, bass, guitar, piano, and "other" — in minutes. Then it gives you everything you need to learn, practice, and create:

• 6-stem AI separation, 100% on device • Per-stem volume, instant solo, and mute • 3-band EQ and stereo pan on every channel • Per-channel and full-song waveforms — tap to jump anywhere • Transpose ±24 semitones without changing tempo • Change speed without changing pitch • A → B practice loops for the toughest sections • Section markers (verse, chorus, solo) to jump instantly • Automatic BPM and key detection • Record up to 4 of your own takes over the song • Vocal effects: reverb, delay, compressor, noise gate, low-cut, distortion • Non-destructive trim on your recordings • AirPlay 2 and Lock Screen / Control Center playback • Export individual stems, the full mix, or just the loop (WAV / MP3) • Light and Dark mode • Available in 8 languages

PRIVACY FIRST Everything happens on your device. MonoBand has no servers, no analytics, no third-party tracking, and no account. Your songs, stems, and recordings never leave your phone.

Import audio from Files, the Photos app (videos too), your Music library, or record fresh. Note: DRM-protected streams (Apple Music, Spotify) cannot be imported — use songs you own.

Made with care for musicians, learners, and producers.
