2 stems
Vocals + instrumental
Choose this layout when you need an acapella, a backing track, or a simple vocal-versus-music split.

AI Stem Splitter for 2, 4, or 6-Track Separation
Turn a mixed song into separate vocal and instrument tracks. Choose the stem layout that fits your remix, practice session, DJ edit, or production analysis.
Upload from your browser, select a separation mode, then preview and download the resulting tracks.
Choose the Right Stem Layout
More stems provide more control, but the simplest useful layout is often the fastest way to organize a project.
4 stems
Vocals + drums + bass + other
A practical balance for remixing, DJ preparation, arrangement study, and broad control over a full mix.
6 stems
Vocals + drums + bass + guitar + piano + other
Use the more detailed split when guitar and piano need their own tracks instead of remaining in the other stem.

Source File Checklist
- Use the highest-quality version of the recording available to you.
- Choose 2 stems when the goal is only vocal isolation or an instrumental.
- Choose 4 or 6 stems when you need independent control over the rhythm and instrument groups.
- Check each output in context. A stem that sounds imperfect solo may still work well when blended into a remix or practice mix.
Workflows for Separated Stems
Stem files are most useful when the output layout is chosen for a specific listening or editing goal.
Prepare a remix
Separate the lead vocal, rhythm section, and harmonic parts before arranging, muting, or processing them in your DAW.
Practice one part
Lower or remove a selected stem so you can play or sing against the rest of the original arrangement.
Study a production
Listen to drums, bass, vocals, and supporting instruments separately to examine timing, tone, and arrangement choices.
Build a DJ edit
Create vocal, instrumental, or rhythm-focused sections that are easier to cue, layer, and transition in a set.
AI Stem Splitting Has Limits
A finished master does not contain the original multitrack session. The splitter estimates sources from overlapping audio, so results vary with the mix.
Reverb, doubled parts, distorted instruments, dense frequency overlap, and low-quality source files can produce bleed or audible artifacts. Preview the outputs before committing to a workflow.
For a vocals-only workflow, see the AI vocal remover. To focus on extracting the singer, use the acapella extractor.
AI Stem Splitter FAQ
What does an AI stem splitter do?
It analyzes a finished mix and estimates separate audio tracks for musical sources such as vocals, drums, bass, guitar, piano, and other instruments. The available output depends on the separation mode you select.
Which stem mode should I choose?
Use 2 stems for vocals and instrumental, 4 stems for vocals, drums, bass, and other, or 6 stems when you also want separate guitar and piano tracks.
Can I split video audio into stems?
The NeuralSound upload interface accepts common audio formats including MP3, WAV, FLAC, and M4A, plus common video formats including MP4, WebM, MOV, and AVI.
Will every isolated stem be completely clean?
Not always. AI separation estimates sources from a mixed recording, so dense arrangements, heavy effects, and overlapping frequencies can leave bleed or artifacts. Starting with the best source file available usually gives the model more detail to analyze.
Can I use separated stems in a release?
Stem splitting does not grant rights to the source recording or composition. Make sure you have the necessary permission or licenses before publishing, distributing, or commercially using material you do not own.
