Stem Splitter vs DeeeMix

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 (Bars, Neon Glow, Glass, Siri-style Fluid, Circular, Retro EQ, Cassette, and more) and 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. WHY OFFGRIDSTEM • 100% on-device — your music never leaves your phone • No ads, ever • One-time purchase — no subscription, no expiring credits • Fast — separation runs locally, no upload/download wait • Private by design — nothing to log in to, nothing to upload WHO IT'S FOR • Singers isolating vocals to study melody and phrasing • Guitarists and pianists isolating their instrument to learn a part • Karaoke and backing-track creators • Remixers and producers pulling clean stems from any track • Anyone who just wants the instrumental (or just the vocals) from a song HOW IT WORKS 1. Import a song, or extract audio from a video 2. OffgridStem separates it into up to 6 clean stems, entirely on your device 3. Mix, mute, solo, adjust pitch/speed per stem 4. Export a mixdown — with your pitch/speed changes baked in — or export individual stems Free to try: your first 3 songs are full-length and fully exportable. After that, previews are capped at 60 seconds unless you unlock Pro. No ads. No subscription. No cloud. Just your music, separated, on your terms.

No subscription. Separation is free with no limits, and the extras (slow playback, saved ranges, export) are a one-time purchase. DeeeMix splits a song into six parts — vocals, drums, bass, guitar, piano and other — so you can listen to each one on its own. Mute the vocals for a backing track, or solo the bass or guitar to work out a line by ear. Separation runs entirely on your iPhone. Your music is never uploaded, and the app works with no network at all. A five-minute song takes well under half a minute. WHAT YOU CAN DO - Split a song into 6 parts (vocals / drums / bass / guitar / piano / other) - Import from videos in the Photos app, or from MOV and MP4 files - Change the volume of each part, mute it, or solo it - Mute the vocals and play the song as a backing track - Drag across the waveform to loop just that range - Set the loop points while the music plays, with Set A and Set B - Skip back 5 seconds or forward 5 seconds - Change the key in semitones, up to 6 up or down: fit a backing track to your voice, or learn a song in an easier key - See the song's reference pitch (A=440, A=442 and so on) BUILT FOR LEARNING BY EAR Working out a song means playing the same few bars over and over, nudging the start a little each time. The range repeat and the 5-second skips are free, with no limits. PRO adds slow playback with the pitch unchanged: tap the speed button to step through 1x, 0.75x and 0.5x, or press and hold it to pick any speed from 0.25x to 1x in 0.05 steps. Passages that were too fast finally come apart. You can also name a range — "chorus", "the two bars before the solo" — and jump straight back to it when you open the app tomorrow. PRO (ONE-TIME PURCHASE) - Slow playback from 0.25x to 1x in 0.05 steps (press and hold the speed button), pitch unchanged - Name ranges and recall them any time, as many per song as you like - Export the parts you chose as a single file, in WAV or M4A - Share all the separated files at once - No ads Separation itself is free, with no limit on how many songs you separate. PLEASE KNOW - The piano part tends to keep traces of other instruments and does not separate as cleanly as guitar. Anything that is not vocals, drums, bass, guitar or piano — strings, wind instruments, synths — is grouped into "other". - Classical music does not work well. It cannot separate strings from woodwinds from brass, and most of the sound lands in "other". - Every part keeps a faint trace of the others, especially cymbals and long reverb tails. A backing track often has a ghost of the vocal in it. - The reference pitch is only measured within a semitone. A song tuned to 442 is detected, but a whole semitone of difference is not: a baroque recording at A=415 reads as roughly A=440. Audio only reveals the key that is sounding, never the key that was written. - You can shift the key up to 6 semitones either way; the further you go, the more muffled voices sound. Exports stay in the original key. - Songs can be up to 15 minutes. DRM-protected files from streaming services cannot be imported. - Please respect the copyright in the original recording when you use what comes out. REQUIREMENTS iPhone and iPad running iOS 18 or later. Available in English, Japanese, Chinese (Simplified and Traditional), Korean, German, French, Italian, Spanish, Turkish, Portuguese (Brazil) and Arabic.
