About
StemSplit is a professional-grade AI vocal remover and stem splitter designed for musicians, DJs, content creators, and developers. Powered by a neural network with 95%+ accuracy, it cleanly isolates vocals from instrumentals and can split any track into up to 6 individual stems — vocals, drums, bass, guitar, piano, and other instruments — in under 60 seconds. The tool accepts all major audio formats including MP3, WAV, FLAC, M4A, OGG, and WEBM up to 100MB, and also processes YouTube and SoundCloud links directly without requiring a separate download. Users can choose between 2-stem, 4-stem, or 6-stem separation modes depending on their needs. Beyond stem splitting, StemSplit offers automatic BPM and musical key detection, Camelot notation for harmonic mixing, beat grids, and one-click Rekordbox XML export — making it a complete workflow tool for DJs. Karaoke creators and cover artists benefit from the instant instrumental and acapella extraction features. StemSplit operates on a credit-based, pay-as-you-go model starting at $0.10 per minute, with no monthly subscription and credits that never expire. New users receive 5 free minutes upon signup with no credit card required. An API is available for developers who want to integrate stem separation into their own applications. With over 5,000 songs processed monthly and a 4.9/5 rating from 2,500+ users, StemSplit is a reliable choice for audio separation at any scale.
