Vocal isolation
Separate the lead vocal from the instrumental bed for practice and creative workflows.
AI audio separation
AI Stem Splitter for Vocals and Instruments
Separate a mixed track into useful musical parts. Sonus helps isolate vocals, drums, bass, piano, and other elements so you can study an arrangement, prepare a remix, create a backing track, or continue production.
Split a track into stemsWork with the parts inside a song
Instrument separation
Access elements such as drums, bass, piano, and other available musical parts.
Faster remix preparation
Begin with separated audio instead of manually rebuilding an entire arrangement.
What is an AI stem splitter?
A stem splitter analyzes a mixed audio file and separates groups of sounds into individual outputs. Depending on the source, these can include vocals, drums, bass, piano, and other instrumental material.
Separation gives creators more flexibility than a single stereo file. You can focus on one part, lower or remove another, study how the arrangement works, or bring selected stems into a broader production workflow.
Use cleaner source audio for better separation
Stem quality depends on the original mix. Clear, high-quality source audio generally gives the model more information than a heavily compressed recording, noisy capture, or file where many sounds occupy the same frequencies.
Separated stems may still contain traces of overlapping sounds. Listen to the results in context and use them as practical production material rather than assuming every source can be separated perfectly.
How to separate a song into stems
Use a source file you are permitted to process and choose the parts you need.
- Step 1
Choose the track
Start with the cleanest available audio file for more useful separation.
- Step 2
Run AI separation
Sonus analyzes the mix and separates supported vocal and instrumental elements.
- Step 3
Review the stems
Listen to each result and continue with remixing, practice, or production.
What separated stems are useful for
Remixes and rearrangements
Work with selected elements while changing rhythm, structure, or instrumentation.
Practice and learning
Focus on a vocal or instrumental part and study how it functions in the mix.
Backing-track preparation
Reduce or isolate selected elements when preparing rehearsal and performance material.
Stem splitter questions
What parts can Sonus separate?
The workflow is designed to isolate vocals and musical elements such as drums, bass, and piano when they are present in the source.
Will every stem be perfectly clean?
Not always. Separation quality varies with the original mix, compression, noise, and how strongly sounds overlap.
What audio should I upload?
Use the highest-quality source file available and only process audio you have permission to use.
Can separated stems be used for remixing?
They can support remixing and production workflows, subject to the rights and permissions attached to the source recording.
