Stem Splitter - Vocal Remover

Split any song into vocals, drums, bass, and instrumentals — entirely on your iPhone.

Stem Splitter is the privacy-first music separator that runs 100% on-device. Import any audio file, separate four clean stems with on-device AI, and export — no upload, no cloud, no waiting in a server queue.

▸ FOUR STEMS, ZERO CLOUD
Apple Neural Engine does the work, on your iPhone, in your pocket.

• Vocals, drums, bass, and other instruments — separated cleanly
• On-device AI — your audio never touches a server
• Works fully offline — on a flight, in a studio, anywhere
• Imports MP3, M4A, WAV, AAC, and FLAC from Files, Voice Memos, and AirDrop

▸ MULTITRACK STEM PLAYER
Hear exactly the mix you want.

• Mute and solo each stem with one tap
• Adjust per-stem volume in real time
• Loop sections to learn covers and rehearse parts
• A/B compare your mix with the original track

▸ EXPORT ANYWHERE
Stems land where you need them.

• Save individual stems as WAV or MP3
• Save your custom mute/solo mix as a single file
• Share to Files, Voice Memos, AirDrop, GarageBand, or any audio app

▸ BUILT FOR
• Musicians learning covers and rehearsing parts
• Producers sampling and remixing tracks
• DJs preparing mashups and edits
• Karaoke fans and acapella makers

▸ PRIVATE BY DESIGN
Your audio stays on your device — always. No cloud uploads, no analytics on your tracks, no servers caching your unreleased songs. DRM-protected Apple Music tracks are blocked at import; bring your own files.
