Struggling to nail that guitar solo, drum fill or vocal line? Isolate the part you're working on, slow it down without changing the pitch, and loop the exact section you're practicing with A-B repeat. Play along until you've got it down.

Built for musicians to level up your practice routine.

Instrument Isolator uses AI to split any song into separate stems — vocals, drums, bass, piano, and guitar with the other melodic parts — so you can hear each part on its own and actually learn it.

WHAT YOU CAN DO
- 🎶 AI stem separation: split a song into 2, 4, or 5 stems
- ♾️ Unlimited separations — no credits, no monthly song limit, no sign-up
- 🎤 Remove vocals for a backing track, or isolate vocals to study a melody
- 🐢 Slow down any stem to practice speed — the pitch stays correct
- 🔁 Loop a section with A-B repeat and drill it hands-free
- 💾 Save the songs you practice so they're always one tap away
- 🎵 Supports all major audio formats (MP3, AAC, FLAC, WAV, and more)

FREE AND PREMIUM
Free: unlimited 2- and 4-stem separations, stem playback, and saving up to 20 songs.
Premium: slow-down, A-B loop, 5-stem separation with piano, unlimited saved songs, and no ads.
- Try the practice tools free on the built-in sample song before you decide.

MADE FOR PRACTICE
Results are excellent for music practice, learning parts, and casual listening — but they're not studio-quality stems. This app isn't intended for remixing or professional production. Some artifacts or bleed between parts will often be heard; this is a natural part of the process.

HOW IT WORKS
Pick an audio file from your device, choose how many stems you want, and the app separates it in about half a minute. Play a stem back, slow it down, loop the hard part with A-B repeat, and save it for next time. Tracks up to 10 minutes long are supported.

GREAT FOR
- Learning songs on guitar, piano, bass, or drums by ear
- Making a karaoke or backing track from a song you love
- Slowing down a fast solo to practice it note by note
- Looping a chorus or verse until you've got it
- Singing over an instrumental, or isolating a vocal to study phrasing
- Separating instruments from a song to practice one part at a time

Separate your song, isolate the part, slow it down, and practice smarter.
