AI MusicianStem Splitter
Split audio into four separate MP3 tracks.
4-track audio separation
Separate a mixed song into vocals, drums, bass, and other instruments. Play and download each available track individually.
Vocals
Drums
Bass
Other instruments
Free-plan generations are public. Subscribers can choose to keep results private.

Inspect a mix through four separate parts
A stem splitter estimates musical parts from a finished recording.
View details
This workflow produces four MP3 tracks: vocals, drums, bass, and other instruments. Each completed track has an individual player and download. The other track groups material that does not belong to the first three, such as guitars, keyboards, or textures; it is not a separate file for every instrument.
Use the results to study an arrangement, practice a part, or prepare material for another editor. Separation can leave spill and artifacts, so the files should be evaluated as estimated parts rather than original studio recordings.
Choose a practical four-track task
Surme Di Line (Flute Melody Version)
Bass
A bassist can focus on the bass output to hear the shape of a phrase that is difficult to follow in a full mix.
A drummer can inspect the drum part for entrances and rhythmic changes. Start with the passage you are learning, then compare it with the original recording. Some notes or transients may be affected by separation. Use the isolated track as a listening aid instead of assuming that it is a complete transcription of the performance.
Download the four tracks and bring the useful parts into your own audio editor.
Decide which musical role you want to change before combining them: a different bass idea, fewer drums under a verse, or an alternate texture. Check file alignment against the source before working on transitions. The separation page provides individual audio outputs; the timeline, balancing, additional instruments, and final export belong to the editor where you build the sketch.
From full mix to four downloads
Select the source and the passage that matters
Upload a recording up to 50 MB and twenty minutes. Use a source with the introduction, ending, and arrangement you want to inspect. If you only need one section, prepare that section before uploading and leave enough surrounding context to recognize the phrase.
Check the selected file and duration before proceeding. A long recording containing unrelated tracks is a poor starting point when your real question concerns one bass line or a drum break.
Review the fixed separation workflow
The stem splitter uses four outputs here; there is no need to choose a two-, four-, or six-track model. Sign in and review the displayed credits and visibility before submitting.
Free-plan generated results are public, and subscribers can choose private results. Follow the task status while processing. Starting duplicate tasks because an output has not yet appeared does not give you a clearer comparison of the same source.
Check every part and keep useful files
After completion, play vocals, drums, bass, and other individually. Listen to a dense section and a simpler one, then compare the part you need against the original. Download each required MP3 and use clear filenames in your project folder.
If you plan to combine parts in another editor, check their starts and endings before arranging them. Keep your original recording and a local copy of the outputs you decide to use.
Understand what belongs in each track
The other category is intentionally broad.

A keyboard sound and a guitar may remain together because this is a four-part separation, not an instrument-by-instrument session export.
Listen for the musical role you need rather than expecting a dedicated piano, string, or backing-vocal channel. If the part you want overlaps strongly with another instrument, the combined output may not be suitable for the edit you had in mind.
Artifacts are often easier to hear when a separated part is exposed.
View details
A bass line that works beneath the full arrangement may sound less natural on its own, and a cymbal may spill into another track.
Compare the section in its intended context. Raising the playback level can reveal detail but does not improve separation. Consider a different passage when the required material cannot be used cleanly enough for your purpose.
Questions about the four-track output
Can I download piano, guitar, or backing vocals as extra tracks?
Not as separate outputs in this workflow. The fixed tracks are vocals, drums, bass, and other instruments. Piano and guitar may be grouped in other; backing voices can be included with vocals or partly remain elsewhere. The page does not offer a six-track mode or recover the recording session’s individual channels.
Is there a ZIP or a lossless format download?
The current delivery is four individually downloadable MP3 files. A ZIP bundle, lossless stem export, and selectable quality tiers are not offered here. Download the tracks you need using their individual controls. No particular MP3 bitrate, sample rate, or original-master fidelity is promised.
Why can I hear the same sound in more than one part?
Separation estimates overlapping sources from a combined recording. Reverb, distortion, and similar frequency content can place fragments in more than one output. Listen to both the isolated part and its planned use before deciding whether the result is workable. It is not proof that the original production had those sounds on the same studio track.
Begin with one part you want to understand
Choose the correct mix and decide whether the task is listening, practice, or a remix sketch. After separation, keep the files that help with that specific task and check them in context before building the rest of your project.
