Stem separation (also called source separation) uses AI to split a mixed song into its individual instrument tracks — such as vocals, drums, bass, guitar, piano, and other instruments. This lets musicians isolate or mute specific parts for practice or study.
No. All processing happens entirely on your iPhone or iPad using on-device machine learning. Your music never leaves your device and no internet connection is required.
Deconpose separates songs into 6 stems: vocals, drums, bass, guitar, piano, and other instruments. You can solo or mute any combination to create the perfect practice track.
Processing runs entirely on your device — no servers, no queues. Powered by Apple-silicon-accelerated on-device AI, a full song is typically ready within a few minutes on a recent iPhone — the latest models separate even a 7-minute song in under a minute, while staying easy on your battery. This is also what makes the one-time purchase model possible: there are no cloud servers to pay for month after month, so neither do you. While stems prepare in the background, you're not left waiting: hit play on the original track, slow it down, shift the pitch to your instrument's key, or set up your loops. All practice tools are available immediately — stems arrive while you explore the song.
Deconpose uses Demucs v4, one of the most advanced AI models for source separation. For most pop, rock, folk, and electronic music you'll get clean, practice-ready stems. Densely layered productions or heavily processed sounds may occasionally show some bleed between tracks — no AI model separates every recording perfectly. In practice, even imperfect stems are more than good enough for learning a part, slowing things down, or singing along — which is exactly what Deconpose is designed for.
Your first song is free — a complete separation with no time limit, and the stems stay yours with unlimited playback. A one-time premium purchase unlocks unlimited songs and stem export. No subscription required.
