AI stem splitter
Separate a song into four stems: vocals, drums, bass, and everything else. Play them together, mute or solo each one, and download them for practice, remixes, or DJ sets.
1. Choose a song
2. Separate
- The first run downloads the AI model (174 MB) once; your browser keeps it for next time. Your song is never uploaded.
3. Listen and download
The vocals, drums, bass, and other stems appear here when the separation is done.
How it works
- Pick a song from your device.
- Press Separate stems: an AI model splits it into vocals, drums, bass, and other, on your device.
- Mute, solo, and mix the stems, then download any stem with one click, or all of them as a ZIP.
What you get from a stem splitter
A stem splitter takes a finished song apart into the parts it was mixed from. This one gives you four stems: vocals, drums, bass, and everything else, such as guitars, keys, and synths. The stems stay in sync, so you can play them together, mute or solo any of them, balance the volume of each, and watch a waveform and a level meter for every stem.
Typical uses are practising an instrument over a backing track, learning a bass line or a drum pattern by ear, making karaoke versions, building DJ edits and mashups, and sampling a clean vocal or drum loop. Download a single stem with one click, or take all four in a ZIP.
Tips for the best separation
Start from the best source you have. A lossless file (WAV or FLAC) or a high-bitrate MP3 gives the AI model more detail to work with than a low-quality rip. If you only need one section of a song, trim it first so the separation finishes sooner.
Dense mixes, heavy reverb, and very quiet vocals can leave faint traces of other instruments in a stem, which is normal for any separation tool. If you only need the voice or only the backing track, the vocal remover and the acapella extractor give you exactly that. Before mixing the stems with other tracks, check the tempo and key of the song.

Frequently asked questions
Which stems do I get?
Four: vocals, drums, bass, and other (guitars, keys, synths, and everything else). Played together they add up to the original mix.
How good is the separation?
It uses a well-regarded open source AI separation model. Results are very good on most pop, rock, and electronic music, though you may hear faint traces of other instruments in a stem, especially on dense mixes.
Can I download just one stem?
Yes. Every stem has its own download button next to its level meter, and you can pick WAV or MP3 first. To get everything at once, use Download all stems for a ZIP with the four files.
Is my song uploaded to a server?
No. The separation runs on your own device, inside your browser. The only download is the AI model itself; your audio never leaves your computer or phone.
How big is the AI model download?
The AI model is about 174 MB. It is downloaded once from SearchSound.cloud the first time you separate a song, then kept in your browser’s cache, so later songs start right away. Clearing your browser data removes it.
How long does separation take?
On a typical laptop it takes about 4 to 5 minutes per minute of music, because the model runs on a single processor core. Browsers with WebGPU (recent Chrome or Edge on a computer with a capable graphics card) can be faster. Phones are much slower and may run out of memory, so a computer works best. Songs can be up to 10 minutes long.
Why does it need so much memory?
The AI model is a large neural network and needs about 3 GB of memory while it works. If the tab crashes, close other tabs and apps, or trim the song first.
Can I use the separated stems in my own releases?
Separating a song does not change who owns it. Use stems of copyrighted songs for personal practice, study, and private remixes, and get permission from the rights holders before publishing or selling anything made from them.
Is this tool free?
Yes. It is completely free, with no account, no watermark, and no limit on how many files you process.
Which file formats are supported?
You can open MP3, WAV, FLAC, M4A, AAC, and OGG files, and download each stem as WAV or MP3, or all of them together as a ZIP file.
