MAKE IT YOURS
Stem Splitter
Explore the parts inside a mix. Separate a supported song into stems and listen to the individual layers that shape its sound.
Split stemsHOW IT WORKS
Start with your idea.
Start separation
Run the stem splitter to prepare the available parts of the mix.
Explore the layers
Listen to the resulting stems and compare them with the original. Use what you hear to study the arrangement or plan your next edit.
A LITTLE MORE DETAIL
Make the most of your next idea.
Study an arrangement one layer at a time
A mixed song can hide small choices that make a big difference: a bass line supporting the chorus, a drum pattern changing between sections, or a vocal sitting above a sparse verse. Stems make those layers easier to inspect.
Use stems for practice and creative exploration
Listen to a rhythm part while learning the arrangement, isolate a layer for closer study, or use the separated parts as a starting point for a permitted edit. The available outputs depend on the separation task.
Expect separation artifacts
The tool estimates components from the finished mix. Overlapping frequencies, effects, and dense arrangements can leave traces between stems, so check each output before relying on it.
GOOD TO KNOW
Questions, answered.
What is an audio stem?
A stem is a separated part of a mix, such as a vocal or instrumental layer. The exact parts depend on the separation task.
Are separated stems the original studio recordings?
No. They are estimates created from the mixed audio, so some sounds or effects may overlap between outputs.
What audio can I split?
Use a supported song from your library or an uploaded MP3 you have the right to process.
