Upload any song and split it into separate vocals, drums, bass, guitar, piano, and instrument stems — free, no signup. Supports MP3, WAV, FLAC and M4A.
An AI stem splitter is a tool that uses artificial intelligence to separate a finished song into its individual audio tracks — vocals, drums, bass, guitar, piano, and other instruments — without the original session files. Upload any audio file, and the AI reconstructs each part as a clean, downloadable stem.
Stem splitters are used by music producers, DJs, remixers, content creators, and musicians for sampling, karaoke creation, remixing, instrument practice, video production, and DAW workflows. The result is the same audio elements you'd get from a studio multitrack — extracted from a single mixed file.
BeatsToRapOn's AI stem splitter is free, runs in your browser, requires no signup, and creates downloadable stems from MP3, WAV, FLAC, and M4A files.
Upload a song and download clean, isolated stems. Up to 6 stems on Studio tier.
Isolate vocals for acapellas, karaoke, remixing
Pull clean drum breaks, kick, snare, hats
Isolate bass guitar or 808 sub-bass
Extract acoustic or electric guitar parts
Isolate piano, keys, and synth chords
Strings, brass, FX, and background music
Upload your audio, choose the stem separation model, and download clean stems in minutes. No software install needed.
Drag and drop an MP3, WAV, FLAC, or M4A file. Higher-quality files usually produce cleaner stem separation.
Select Basic or Pro for vocals, drums, bass, and other instruments, or use Studio for deeper stem separation.
Listen to each stem before exporting. Download individual stems or the full package for remixing, practice, karaoke, or DJ edits.
A quick guide to common stem outputs, plus a short preview so you know what to expect.
Chop sampled drums, isolate vocal hooks, and rebuild arrangements. The AI extracts clean stems you can drag straight into Ableton Live, FL Studio, Logic Pro, or Pro Tools — no plugin required. Producers use the splitter daily for beat-flipping, mashups, and sample chopping from vinyl-era source material.
Pull a clean acapella for a mashup or grab the instrumental for a live set. Vocal isolation stays tight, the kick keeps its punch, and the bass doesn't wobble on mono-sum. Drop the stems into Rekordbox, Serato, or Traktor as standard WAV files.
Strip vocals to create karaoke tracks, isolate a hook for cover content, or pull background music for podcasts and video. Works as a vocal remover, an instrumental maker, and a full stem splitter — same upload, multiple outputs.
Separate dialogue from background music in a single upload. Pull clean drums for cinematic transitions, isolate vocals for ducking, or strip music from a clip when you need clean voiceover. Drag straight into Premiere, DaVinci Resolve, or Final Cut.
Most stem splitters fall into a few categories. Here's how the main approaches differ, so you can pick what fits your workflow.
Tools like BeatsToRapOn run entirely in your browser with a free tier — no install required. BeatsToRapOn's Fast & Basic tier is free with a daily allowance and no signup, splitting any song into 4 stems. Best when you want speed and zero setup.
Some popular separators are built around paid subscriptions or credit packs, often with a limited free allowance to start. Worth checking each tool's current pricing page directly, as plans change. Best when you split high volumes and want a dedicated paid product.
Open-source options and DAW-built-in splitters are free but need installation or a capable machine. Best when you want full local control, offline processing, and don't mind the setup.
BeatsToRapOn's free tier runs in any browser with no signup and no install. Paid tiers add 6-stem separation with guitar and piano. Pricing and features for other tools change often — always check their current pages before deciding.
How modern AI stem splitters work, which models matter, and how to get professional results from any song.
An AI stem splitter is a deep neural network trained on thousands of hours of multitrack recordings where each instrument was already isolated during production. At training time, the model sees the mixed stereo track as input and the clean individual stems as the target output. Over millions of training iterations, the network learns the acoustic fingerprint of each instrument class — the attack envelope of a kick drum, the harmonic stack of a vocal, the frequency signature of a bass guitar — and how those elements overlap in a dense mix.
At inference time, you upload a full track and the model predicts the contribution of each instrument class from that single mixed input. The result is a set of separated audio stems that didn't exist as files before — the AI reconstructs them from learned patterns.
Modern AI stem splitters use neural networks trained to recognise patterns in mixed audio. Older systems worked mainly from spectrograms, while newer models can analyse waveform detail, frequency content, timing, transients and harmonic structure at the same time.
BeatsToRapOn uses multiple separation approaches depending on the selected tier and the type of audio being processed. Fast modes prioritise speed for quick vocal, drum, bass and instrument separation. Studio modes prioritise cleaner separation and additional outputs such as guitar and piano.
The practical result is simple: upload one finished song and export separate stems you can use for remixing, sampling, karaoke, DJ edits, practice, or DAW production.
No single stem separation approach is best for every mix. Dense vocals, distorted guitars, live drums, 808 bass and reverb-heavy recordings all separate differently. BeatsToRapOn uses different processing modes by tier, so users can choose faster 4-stem separation for quick work or Studio mode when they need additional guitar and piano outputs.
Watery vocals come from lossy source files, heavy reverb in the original mix, or stacked backing vocals. Fix: upload a WAV or FLAC instead of MP3, and apply a light de-reverb plugin post-split rather than pushing the splitter harder.
Hi-hat smear in the instrumental happens when the model misclassifies high-frequency percussion as sibilance. The Wavz Studio ensemble mitigates this because HTDemucs handles high-frequency drums better than Mel-Roformer does alone.
Bass wobble on mono-sum usually means the original mix had wide stereo processing on the low end. Fix: mono the sub range (below 120 Hz) after splitting and apply a light high-pass on the other stems.
Every stem exports as a standard WAV or MP3 file that drops directly into any DAW. In Ableton Live, drag each stem onto its own audio track for warping and arrangement. In FL Studio, drop them into the Playlist as audio clips or load into the Sampler. Logic Pro users typically use Flex Time and comping on vocal stems. Pro Tools handles them as standard audio regions. No plugin or integration required.
For hip-hop producers, the high-value workflows are drum chopping and melody flipping. Isolate the drum stem from a soul record to chop a break for a new beat, or isolate the instrumental from a vocal-heavy track to flip the melody around new drums. The Wavz model handles vintage vinyl recordings and background noise more gracefully than generic Demucs because it was trained on the kind of low-fidelity source material hip-hop producers actually sample.

Fast & Basic (4 stems, free): quick Demucs pass for previews, karaoke, or one-off splits. Wavz Pro (4 stems): the Wavz transformer on vocals, drums, bass, and other — cleaner than the free tier, faster than Studio. Wavz Studio (6 stems): full ensemble routing, adds guitar and piano separation. Aurora Pro / Aurora Studio: our alternative engine, strongest on modern high-production records. Choose Studio when you need the cleanest possible output for a release; choose Pro or Basic when you need speed.

How AI stem splitters work, which models we use, how to split songs into stems, and how to get cleaner results in your DAW.
An AI stem splitter is a deep neural network trained on thousands of hours of multitrack recordings where each instrument was isolated during production. The model learns the acoustic fingerprint of each class — the attack of a kick drum, the harmonic stack of a vocal, the signature of a bass guitar. At inference time, it predicts the contribution of each instrument from a single mixed stereo input and reconstructs clean stems. Modern hybrid transformer architectures like our Wavz model operate in both the waveform and spectrogram domain simultaneously, which produces cleaner transients and fewer artifacts than older spectrogram-only models.
BeatsToRapOn runs an ensemble of four models: HTDemucs (Hybrid Transformer Demucs) for broadband separation, Mel-Roformer for vocal isolation, vanilla Demucs for fast-tier processing, and our own Wavz model — a hybrid transformer architecture trained on thousands of hours of meticulously labelled song data across hip-hop, trap, R&B, afrobeats, drill, and rock. Our Studio tier routes uploads through whichever model scores highest for that mix profile and reconstructs the six stems from the ensemble output.
A basic vocal remover usually creates two files: vocals and instrumental. BeatsToRapOn is a full AI stem splitter, so you can separate a song into vocals, drums, bass, instruments, and on Studio tiers, guitar and piano as well. Use vocal removal for karaoke or acapellas. Use full stem separation when you need remix control, DJ edits, sampling, arrangement changes or DAW production.
Watery artifacts usually come from one of four causes: a lossy source file (always upload the highest-quality version you have), heavy reverb or delay on the original vocal that the model reads as instrumental content, stacked backing vocals bleeding across the separation, or aggressive stereo widening in the original mix. Fixes: use Wavz Studio instead of the 4-stem free tier, upload WAV or FLAC, and apply a light de-reverb plugin post-split rather than pushing the splitter harder.
Yes. The Fast & Basic tier splits any song into 4 stems — vocals, drums, bass, and instruments — at no cost, with a daily free allowance and no signup required. Paid plans (Wavz Pro, Wavz Studio, Aurora Pro, Aurora Studio) give access to cleaner models, 6-stem separation that adds guitar and piano, and higher file size limits.
Upload your audio file (MP3, WAV, FLAC, or M4A) using the uploader at the top of this page. Choose how many stems you want — 4 stems on the free tier, 6 stems on Wavz Studio or Aurora Studio. The AI processes the track in under 90 seconds for most 3-minute songs. Preview each separated stem in your browser, then download individually or as a single ZIP. No software install, no signup for the free tier.
Direct YouTube URL splitting is not currently available. Upload an audio file you own, created, or have permission to use. BeatsToRapOn supports MP3, WAV, FLAC and M4A uploads for online stem separation.
You can use stems generated from audio you own or have licensed — your own recordings, cleared samples, or licensed sessions. For copyrighted material owned by someone else, you still need a licence from the rights holder before release. BeatsToRapOn doesn't claim ownership of stems generated from your uploads and does not train on your audio files.
Every stem exports as a standard WAV or MP3 file that drops directly into any DAW — no plugin required. Ableton Live users drag each stem onto its own audio track for warping and arrangement. FL Studio users drop them into the Playlist as audio clips. Logic Pro users typically use Flex Time and comping on vocal stems. Pro Tools handles them as standard audio regions. For cleanest DAW import, always export as WAV (lossless) rather than MP3.
2-stem (vocals + instrumental) is fastest and good for karaoke or quick acapella lifts. 4-stem (vocals, drums, bass, other) covers most remix and DJ use cases. 6-stem (vocals, drums, bass, guitar, piano, other) is the producer tier — you need it when you're sampling a specific instrument or rebuilding an arrangement. Wavz Studio and Aurora Studio both ship 6 stems; the free and Pro tiers ship 4.
For hip-hop producers, the high-value workflows are drum chopping and melody flipping. Isolate the drum stem from a soul record to chop a break, or isolate the instrumental from a vocal track to flip the melody around new drums. Our Wavz model handles vintage vinyl and background noise more gracefully than stock Demucs because it was trained on the kind of low-fidelity source material hip-hop producers actually sample. Full workflow: How to Craft Professional Rap Beats Using AI Stem Splitter Tools.
Upload MP3, WAV, FLAC, or M4A. WAV and FLAC produce the cleanest separation because they're lossless — the model has more signal to work with. Stems export as WAV (lossless, DAW-ready) or MP3 (smaller file, faster download). For the sharpest separation, always use the highest-quality source file you have.
