An acapella is a song's vocals with the music taken away. Producers use them for remixes, mashups and samples, singers to study a performance, and DJs to layer a vocal over another track. Unless the artist released an official acapella, the only way to get one is to separate it out of the finished song, and that is what this tool does with an open-source AI model running in your browser: Spleeter for Fast quality, or HT-Demucs fine-tuned for vocals for Best quality. Your song is never uploaded.
How to use it
- Drop in a song, or a music video to use its audio track.
- Keep the AI vocal extractor selected and pick Fast or Best quality. The first run downloads the model (38 MB for Fast, 158 MB for Best), then it is cached for every song after.
- Press Extract vocals, play the acapella in the page, and download it as a WAV. The instrumental is right below it.
What it will not do
Separation is an estimate, not the original vocal recording. Reverb and effects on the voice stay with it, harmonies and backing vocals come out together with the lead, and instruments in the same range as the voice can leave a faint trace. For the cleanest acapella use Best quality, ideally in a browser with WebGPU (recent Chrome or Edge).
Frequently asked questions
Is my song uploaded to a server?
No. The song is decoded and separated inside your browser tab. The only network traffic is the AI model downloading to you the first time - your file never leaves your device.
How do I get the acapella of a song?
Drop the song in, keep the AI model selected, and press Extract vocals. When it finishes, the acapella (vocals only) is the first result: play it in the page, then download it as a WAV. The instrumental comes with it.
How clean will the vocals be?
Usually clean enough to remix, sample or sing along to, but not studio-perfect. Reverb on the voice comes through with it, and instruments that share the voice's range (a lead guitar, a synth line, strings) can leave a faint trace. Best quality gives noticeably cleaner vocals than Fast: in our test on a song with known stems, Fast scored 5.8 dB and Best 8.7 dB on the vocals (SDR, higher is cleaner).
What is the difference between Fast and Best quality?
They are two different AI models. Fast is Spleeter 2-stems from Deezer, a 38 MB download that splits a 3-minute song in seconds and runs on phones. Best is HT-Demucs fine-tuned for vocals, a 158 MB download that is cleaner but needs much more memory and is slow without WebGPU. The page picks the one your device can handle, and you can run Best afterwards on the same song with one click.
Can I use the acapella in my own remix?
Technically yes, but the vocal still belongs to whoever owns the song. Extracting it doesn't give you the right to release it: for anything you publish, use a song you own or get permission (some artists share official acapellas for remix contests).
Can I get the drums or bass on their own too?
Not here: this tool splits a song into vocals and everything else. The Stem Splitter separates vocals, drums, bass and other instruments into four tracks.
What formats can I use?
Anything your browser can decode: MP3, WAV, M4A, AAC, OGG, Opus, FLAC, or the audio track of a video. Both results come out as 44.1 kHz stereo WAV.
How long does it take?
Fast quality takes a few seconds for a 3-minute song on a recent computer (plus the one-time download), and longer on older computers and phones. Best quality can take several minutes on a CPU and is much faster in a browser with WebGPU. The page shows an estimate for your device before you start, then the time left once it is running.
