About AI Stem Separation
What is AI Stem Separation?
AI Stem Separation is a browser-based tool that uses Demucs models to split any song into separate stems—vocals, drums, bass, guitar, piano, and other. You can also remove vocals in one click. It’s designed for musicians, teachers, podcasters, and content creators who need clean tracks for remixes, karaoke, practice, or editing.
Problem it solves
Traditional stem separation requires expensive software, VST plugins, or unreliable online tools. AI Stem Separation removes the friction: no install, no subscription, and no credit expiry. You pay only for audio minutes you use, and failed jobs refund minutes automatically.
Who it’s for
It’s ideal for music teachers assigning ear-training homework, DJs building mashups, video editors pulling instrumentals for social clips, and hobbyists making karaoke tracks. If you need occasional stem separation without a monthly commitment, this tool fits. It’s not for real-time processing or heavy batch work—each upload has a duration and size limit.
Key use cases
Practice & karaoke tracks: isolate vocals or full layers. Mashups & layer edits: grab acapella and drum tracks. Clean beds for videos/podcasts: export MP3 or WAV for your editor. Teachers: isolate drums or bass for ear training.
Key features
- Demucs models — Choose 2-stem, 4-stem, or 6-stem separation; model-transparent for predictable quality.
- Browser workspace — No VST or desktop install; works on Windows, Mac, Chromebook.
- YouTube & SoundCloud import — Paste a link to process audio directly when you have rights.
- Minute packs that never expire — Buy 30, 100, or 300 minutes; no monthly fees.
- MP3 & WAV export — Depending on plan, download full-quality stems in both formats.
- Failed jobs refund — If a split fails, minutes are returned to your balance.
