SongStems vs SoundLab

SongStems uses AI-powered stem separation to break any song into individual tracks — vocals, drums, bass, and more. Everything runs on your device, so your music library stays completely private. Whether you're a singer creating instant backing tracks or a musician drilling a tough passage, SongStems helps you learn faster. REMOVE VOCALS & ISOLATE STEMS Strip out vocals to create karaoke-style backing tracks in seconds. Isolate drums, bass, or other instruments so you can focus on the part that matters to you. 100% ON-DEVICE — YOUR MUSIC STAYS PRIVATE All stem separation happens locally on your iPhone or iPad. Nothing is uploaded, nothing is shared. Your music is yours. LOOP & PRACTICE Set loop points around any section of a song and repeat it until it's second nature. Slow it down without changing the pitch — perfect for mastering difficult riffs, solos, or vocal runs. REMIX YOUR LOOPS Slice any loop on the beat and rearrange it into something new. Smart Roll builds musical phrases that keep the downbeat where it belongs, or shuffle, scramble, and build your own pattern by hand. Add reverse, stutter, gate, and tape-stop effects to any slice, then jam the slices live on a pad grid and punch them into the sequence. Every remix follows your song's stems, speed, and pitch. BUILD PLAYLISTS Organize your practice sessions by creating playlists of songs and stems. Queue up your setlist, group songs by key or difficulty, or build a warm-up routine — whatever fits your workflow. EXPORT YOUR STEMS Save separated tracks to use however you like — bring them into your DAW, share them with bandmates, or keep them for practice on the go. FREE TO START Try stem separation free, and preview remixing before you buy. UNLOCK EVERYTHING A single in-app purchase unlocks unlimited stem separations and unlimited saved remixes — no subscriptions, no hidden fees.
