Isolate the part you're working on, slow it down without changing the pitch, and loop the exact section you're drilling 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 instrument stems — vocals, guitar, bass, drums, piano, and more — so you can hear each part on its own and actually learn it.

WHAT YOU CAN DO
- 🎶 AI stem separation: split a song into vocals, guitar, bass, drums, piano, and more (2, 4, or 5 stems)
- 🎤 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 to start, no sign-up required

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. ## Rankings - #1,317,360 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.FOREGROUND_SERVICE_MEDIA_PLAYBACK` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.WAKE_LOCK` - `com.android.vending.BILLING` - `com.android.vending.CHECK_LICENSE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` - `com.google.android.providers.gsf.permission.READ_GSERVICES` - `com.ops.instrumentisolator.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [Split It](https://chrome-stats.com/d/com.tchiklh.splitit.app) — 103 users - [Practice Pro - AI Music Tools](https://chrome-stats.com/d/com.chaosaudio.practicepro) — 512 users - [StemScriber](https://chrome-stats.com/d/com.kozelski.stemscriber) — 17 users - [Song Sift: Stem Splitter](https://chrome-stats.com/d/com.letras.songsift) — 14,031 users - [Stem Capture](https://chrome-stats.com/d/com.masahide.stem_capture) — 1 users - [Gaudio Studio: AI Separator](https://chrome-stats.com/d/com.gaudiolab.gs.musician) — 48,306 users, 2.65 / 5 - [Backtrackit: Musicians Player](https://chrome-stats.com/d/com.superpowered.backtrackit) — 2,924,280 users, 4.17 / 5 - [Vocal Remover AI: Stems Lab](https://chrome-stats.com/d/com.nightingale.stemslab) — 8,118 users, 4.00 / 5 - [QuickPlayer – Music Practice](https://chrome-stats.com/d/com.quickplayer.quickplayer) — 115 users - [Sonic Split: Vocal Remover](https://chrome-stats.com/d/com.sonicsplit) — 298 users - [Vocal Remover & AI Separator](https://chrome-stats.com/d/ai.vocal.remover.karaoke.maker.ninja.android) — 19,170 users, 4.37 / 5 - [Riff Studio: Music Practice](https://chrome-stats.com/d/net.brazzi64.riffstudio) — 732,573 users, 4.41 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.ops.instrumentisolator)
