Stem Splitter vs Deconpose

Split any song into clean, isolated stems — 100% on your device, no cloud, no waiting, no subscription. NEW: 6-STEM SEPARATION OffgridStem now separates Vocals, Drums, Bass, Guitar, Piano, and Other — not just the standard 4. Study a guitar riff note-for-note, isolate the piano part, or build a cleaner instrumental than ever. NEW: LIVE REACTIVE VISUALIZER Your exported mixdowns now live in a dedicated Exports player with a real-time, audio-reactive waveform — 14 visual styles including Bars, Neon Glow, Glass, Siri-style Fluid, Circular, Retro EQ, Cassette, and more, plus 4 color themes. Turn your phone sideways for an immersive fullscreen view. NEW: PITCH & TEMPO IN YOUR EXPORTS Shift the key, slow down the tempo to learn a part — your exported mixdown now matches exactly what you heard, not the original. NEW: AUTOMATIC BPM DETECTION Every separated song gets an estimated tempo, shown right where you’re already adjusting playback speed — no need to look it up separately.
