Turn one eligible stereo mix into six private working tracks: vocals, drums, bass, guitar, piano, and other. Inspect or edit each musical role separately.
Choose the mix to decompose into six independently playable arrangement groups.
A new upload remains for seven days. One prepared source produces six private My Songs outputs; complex mixes may retain minor artifacts.
One source produces the complete six-part set. Review every stem beside the original so separation artifacts and useful material remain easy to identify.
Choose an authorized My Songs item or upload a supported source. A clean stereo file gives the separator the strongest basis for distinguishing overlapping musical roles.
Run one separation for the complete set. The system estimates vocals, drums, bass, guitar, piano, and a final other track from the same combined mix.
Review all six private outputs beside the source in My Songs. Check dense passages for bleed before downloading, balancing, looping, or replacing individual roles.
One analysis writes six role-specific results beside the original: voice, percussion, low end, guitar, piano, and residual material. Solo or download a role without rerunning the source for every category.
Masking creates uncertainty. When instruments share notes, transients, effects, or stereo position, energy may appear in more than one estimate. Treat each file as measurable production material, never a recovered multitrack.
Lead and supporting voices are estimated apart from the surrounding instrumental production.
Percussive evidence such as kicks, snares, and cymbals is collected in the drum output.
Low-frequency notes and tonal bass material are assigned to an independent working file.
Detected guitar content becomes a separate file for analysis, editing, practice, or sampling.
Recognized piano material is isolated for transcription, focused listening, or new arrangement decisions.
Remaining synthesis, strings, effects, and uncategorized musical content share the Other output.
True multitracks come from the recording session, where every role was captured separately. When those files are unavailable, a stem splitter estimates which time-frequency material belongs to each category inside the finished mix. That reconstruction is faster than repeated spectral editing or phase work, but it can leave bleed wherever instruments share space. Treat the six outputs as production material to verify, not recovered originals.
The six-part workflow can be started without account setup: provide an authorized source and request vocals, drums, bass, guitar, piano, and other together. Keeping all outputs beside the same recording makes later evaluation clearer, whether the task is arrangement study, practice, or remix preparation. Free access changes neither the need for source permission nor the possibility of separation artifacts.
Choose by output map and working environment. AI2Rap runs one cloud job that always returns vocals, drums, bass, guitar, piano, and other as private My Songs artifacts. LALAL.AI's current official materials describe up to 10 cloud stem choices across web and desktop, plus seven-stem local processing in its desktop app and VST plugin. Neither feature list proves better separation for a particular mix; test the source that matters and select the path whose stem categories, privacy model, and DAW handoff match the project.
Match the output count to the decision. Six-stem mode estimates vocals, drums, bass, guitar, piano, and other for role-level work; Vocal Remover makes the simpler vocal/instrumental pair.
Full arrangement access requires six components
Choose Stem Split when the arrangement needs six independently usable musical roles.
A two-file split for voice and backing only
Choose Vocal Remover when the job needs only a vocal track and its instrumental counterpart.
Open Vocal RemoverAuthorize one source and run one complete analysis. AI2Rap saves the six component estimates as separate private artifacts linked to that source.
Before submission, audition the upload or My Songs source for clipping, heavy ambience, and the densest overlap you will need to separate.
Authorize one analysis that writes all six estimates from the same timing reference; do not rerun the master separately for each role.
As files complete in My Songs, solo the vocal, rhythm, bass, harmonic, and Other roles against identical passages in the source.
Use My Songs to inspect each separated part beside its source as the outputs complete.
Choose six-stem separation when arrangement roles matter individually. Use Vocal Remover when a vocal-and-instrumental pair is sufficient.
Evaluate the vocal estimate away from the master to study phrasing, prepare an acapella reference, or determine whether another voice-focused operation has useful material to work with.
Inspect drums and bass as separate timing systems. Their interaction exposes the pocket for production study, rhythm-focused transitions, and practice against either the low end or percussion alone.
Use the six-track set when a remix decision targets one arrangement role. Mute, loop, replace, or rebalance that estimate while retaining the source as the timing and structure reference.
Separate guitar, piano, and residual material to make obscured harmonic movement easier to hear. Students can follow one role at a time while checking uncertain voicings against the original mix.
Solo vocals to inspect delivery, drums for transient timing, bass for low-end notes, guitar or piano for harmonic roles, and Other for remaining synthesis, strings, effects, or uncategorized material. Every file is an estimate from the same stereo source, not an original session multitrack.
Prefer the cleanest available version. Lossy compression, clipping, dense arrangements, stacked vocals, reverb, and distortion reduce the evidence available for assigning overlapping sound. WAV or FLAC avoids another lossy encode, but no file extension can recover detail already missing from the mix.
Solo the estimate, then switch rapidly between it and the same passage in the master. Listen for another role entering with shared notes, transients, effects, or stereo position. Check dense hooks and transitions first; bleed often becomes clearer there than in a sparse intro.
Use the outputs for arrangement study, practice, transcription support, authorized remix preparation, or replacement tests. Pick Vocal Remover instead when the only decision is voice versus backing; six-stem separation is useful when an individual instrument role must be inspected.
Upload MP3, WAV, M4A, AAC, OGG, or FLAC up to 100MB, or choose an eligible My Songs source. A new upload remains for seven days. The workflow saves six private results beside the source in My Songs so each role can be reviewed as it completes.
Separation creates working files but grants no copyright, master-use, publishing, sampling, or distribution permission. Use only audio you own or are authorized to process, and confirm that the intended remix, sample, practice file, or DJ edit is covered before export or release.
