StemWave

Split any song into six clean, independent stems — vocals, drums, bass, guitar, piano, and other — right on your iPad or Mac. StemWave uses an on-device AI model to separate audio, with nothing ever uploaded to the cloud.

Try it free: separate 2 songs with every feature unlocked. Unlock unlimited songs with a single one-time purchase — no subscription.

Load a track and you get a full practice studio. Mute or solo any part, set its volume, and shape it with a 5-band EQ. Loop a tough section, change the key, or slow the tempo down without changing pitch. Follow along on a big, zoomable waveform and drop named markers to jump straight to the chorus, solo, or bridge.

Want to play along? Record yourself through your mic or audio interface and your take becomes its own stem — mix it with the rest, keep it across sessions, and export when you're ready.

WHAT YOU CAN DO • Separate any song into 6 stems, processed entirely on your device • Mute, solo, and balance each part with per-stem volume and 5-band EQ • Loop A–B sections for focused practice • Change key and adjust tempo independently • Zoomable waveform with named, jumpable markers • Record play-along takes that become mixable stems • Export individual stems as AAC or MP3

LEARN (Beta) — FREE Learning guitar or bass? The built-in trainer shows scales on an interactive fretboard, plays looping exercises at your own tempo, and tracks your practice progress and streaks. Included free, with no limits.

FREE VS UNLIMITED Free: separate 2 songs, with every feature and the full Learn trainer. Unlimited (one-time purchase): separate as many songs as you want, forever. Songs you already separated always keep working.

PRIVATE BY DESIGN Your audio never leaves your device. There's no account to create, no ads, and no tracking. StemWave works fully offline.
