Separate a mixed track into stems
In today’s music ecosystem, the ability to access individual audio stems like vocals, drums, bass, or instruments is key to unlocking new creative, commercial, and educational opportunities. Yet in most cases, especially with legacy recordings or third-party masters, only the final mixed version of a track is available. This makes it nearly impossible to isolate elements for remixing, re-editing, or repurposing the music or vocals.
Unless you are the original producer or have been officially commissioned to remix a track, chances are you don’t have access to the separate stems. For back catalog recordings, even labels and publishers may only hold a merged master. As a result, use cases such as sync licensing, karaoke creation, teaching, remix culture, or reissues often hit a technical wall: there’s simply no way to work with the music beyond the mixed version.
Turn any song into a flexible creative asset
Our Stem Separator technology uses advanced signal separation models to isolate individual elements vocals, drums, basslines, harmonic instruments, and more from any mixed track. It enables high-quality separation of audio sources, even from compressed formats or old masters, opening up a new layer of flexibility for music content.
This is particularly useful for professionals and platforms that deal with catalog exploitation, creative editing, or educational content. Stem separation makes mixed audio usable again, whether for remixing, karaoke, DAW projects, or interactive experiences.
Bringing Studio Access to Any Track
What can content platforms and catalog owners expect?
Production music libraries can offer customizable edits of existing tracks. Record labels and publishers can generate new masters for sync without requiring the original sessions. Music estates can revive catalog titles for new commercial uses. Karaoke and music learning apps can isolate vocals or instruments for targeted interaction. Casual producers, DJs, and DAW users can extract the stems they need to remix or reinvent a song with precision and creative freedom. For all these segments, the value is the same: transforming a static, mixed audio file into editable, modular components ready for today’s music workflows.
Give music new life, one stem at a time
With our stem separation engine, legacy recordings become remix-ready. Catalogs become flexible and dynamic. And creators, educators, and curators gain full control over audio content, whether for learning, licensing, performance, or pure experimentation.
Frequently Asked Questions
What stems can be extracted?
Our system typically separates vocals, drums, bass, and other instruments.
Does this work on compressed or old audio?
Yes. Our technology is optimized to handle a wide range of audio formats and conditions, including legacy or low-fidelity masters.
Can this be used for karaoke or music education?
Absolutely. Isolated stems enable interactive learning environments and karaoke systems by letting users mute or solo specific parts.
Is the separation clean enough for professional use?
Yes. The quality is suitable for sync, remix, and broadcast applications, and is tailored to meet the standards of audio and music professionals.
How does this compare to Deezer’s Spleeter or Meta’s Demucs v4?
While both achieve solid results, our model outperforms them with an average SDR of 9.3 across four stems and fewer audible artifacts. SDR (Signal-to-Distortion Ratio) is a score the music information retrieval community typically uses for measuring quality.
