2-track separation
Use a simple vocal-versus-accompaniment split when you only need the voice, the backing track, or both.

Audio Separation for Vocals, Stems, and Instrument Groups
Split mixed audio into useful parts instead of working from one finished file. Use NeuralSound when you need vocals, accompaniment, drums, bass, guitar, piano, or other instrument groups separated for the next step.
Upload a file, choose the separation depth, preview the outputs, and download only the tracks you need.
Choose the Separation Depth That Fits the Task
The right output is usually the smallest set of tracks that still gives you enough control for the job.
4-track separation
Break the mix into vocals, drums, bass, and other instruments for remixing, study, and broad arrangement control.
6-track separation
Choose the deeper layout when guitar and piano should be isolated instead of staying grouped inside the other-instruments stem.
How Audio Separation Works in Practice
Audio separation is most useful when the output choice is tied directly to what you plan to do after the split.
- 1
Upload the source
Select a supported audio or video file from your device.
- 2
Choose 2, 4, or 6 tracks
Match the separation layout to the editing, study, or performance workflow you need next.
- 3
Preview the separated results
Listen for bleed, artifacts, or missing detail before exporting anything.
- 4
Download the useful outputs
Keep only the vocal, accompaniment, or instrument groups you actually need.
Decision Guide
- Choose `2-track` when you only need the voice and the rest of the mix separated.
- Choose `4-track` when drums and bass also need to be separated from the remaining accompaniment.
- Choose `6-track` when guitar and piano should have dedicated outputs instead of staying grouped.
- Start with the best source available. Higher-quality input usually gives the separator more detail to work with.
Common Audio Separation Workflows
Separation is useful when you need specific parts of a finished mix instead of the entire track at once.
Remix and edit preparation
Separate the vocal and instrument groups before rearranging a track, building loops, or creating transitions in your DAW.
Practice and teaching
Lower or solo a selected part so you can rehearse against the rest of the arrangement or focus on one musical role at a time.
Production analysis
Listen to the rhythm section, vocal, and supporting instruments separately to study tone, balance, and arrangement choices.
Content and reference work
Prepare cleaner vocal, accompaniment, or instrument-focused outputs for demonstrations, reviews, or educational material.
Separated Audio Is Still an Estimate
A mastered file does not contain the original session tracks. The separator estimates those parts from overlapping frequencies and effects, so results vary with the mix.
Dense arrangements, distortion, reverb, harmonies, and low-quality uploads can all leave bleed or artifacts. Review the outputs before building a workflow around them.
For a deeper stem-layout page, see the AI stem splitter. If you mainly want to remove the lead voice from a track, use the voice remover.
Audio Separation FAQ
What is audio separation?
Audio separation is the process of splitting a mixed recording into estimated source tracks such as vocals, accompaniment, drums, bass, guitar, piano, and other instruments.
How is audio separation different from simple vocal removal?
Vocal removal is one narrow use case. Audio separation is broader because it can also break the rest of the mix into multiple instrument groups instead of only producing a vocal and an accompaniment track.
When should I choose 2, 4, or 6 tracks?
Use 2 tracks for voice versus accompaniment, 4 tracks for vocals, drums, bass, and other, or 6 tracks when guitar and piano also need their own isolated outputs.
Can I use audio separation on video soundtracks?
The NeuralSound workflow accepts common audio and video uploads, which is useful when the material you want to separate is embedded in a clip.
Will separated tracks sound exactly like original multitracks?
No. The outputs are estimates from a mixed file, so dense arrangements, strong effects, and overlapping frequencies can leave bleed or artifacts in the separated tracks.
Can I publish separated tracks commercially?
Only if you have the required rights to the source recording and composition. Separation is a technical process and does not change ownership or licensing requirements.
