Stem Splitter
Separate audio tracks into individual stems for remixing and production
Overview
The Stem Splitter uses advanced AI to separate any song into individual instrument tracks (stems). Extract vocals, drums, bass, and other instruments from any recording for remixing, sampling, or educational purposes.
How It Works
- Upload Audio - Select your audio file (MP3, WAV, FLAC supported)
- Choose Separation Mode - Select 2-stem, 4-stem, or 6-stem separation
- AI Processing - Our neural network analyzes and separates each component
- Download Stems - Get individual tracks for each separated element
Separation Modes
2-Stem Separation
Separates into:
- Vocals - All vocal content
- Accompaniment - All instruments combined
Best for: Quick vocal/instrumental separation, karaoke creation
4-Stem Separation
Separates into:
- Vocals - Lead and backing vocals
- Drums - All percussion elements
- Bass - Bass guitar and bass synthesizers
- Other - All remaining instruments (guitars, keys, synths, etc.)
Best for: Remixing, sampling, music production
6-Stem Separation
Separates into:
- Vocals - Lead vocals
- Backing Vocals - Background and harmony vocals
- Drums - Percussion and drums
- Bass - Bass instruments
- Piano/Keys - Keyboard instruments
- Other - Remaining instruments
Best for: Detailed remixing, educational analysis, professional production

Frequently Asked Questions
What's the difference between Vocal Remover and Stem Splitter?
Vocal Remover is optimized specifically for separating vocals from instrumentals with the highest quality. Stem Splitter separates multiple elements but may have slightly less vocal separation quality in exchange for more versatility.
Can I recombine the stems?
Yes! The stems are phase-coherent and can be imported into any DAW and mixed back together. This allows you to adjust individual levels or remove specific elements.
Why do some songs separate better than others?
Separation quality depends on the original recording and mixing. Songs with clear frequency separation between instruments, recorded in studios with professional equipment, typically produce the best results.
