Vocal Remover & Stem Splitter
Separate the voice from the music in your own recordings and videos. The AI (HTDemucs) runs on your device — nothing is uploaded.
Free · No sign-upHow to use Vocal Remover & Stem Splitter
- 1. Drop your own audio or video file (MP3, WAV, M4A, FLAC, MP4, MOV, WebM…) into the box. It is read in your browser — nothing is uploaded.
- 2. Pick 2 stems (vocals + instrumental) to remove background music or vocals, or 4 stems (vocals, drums, bass, other) for remixing.
- 3. Click Separate. The first time, the AI model (126 MB) downloads once and is cached; then the file is processed in 7.8-second pieces with a progress bar and a Cancel button.
- 4. Play each stem, choose WAV, MP3 or M4A — or, for a video, MP4 to keep the picture with the new soundtrack — and download.
Frequently asked questions
Is my audio or video uploaded?
No. The file is decoded and separated entirely in your browser. The only download is the AI model itself (126 MB, once), fetched from Hugging Face and then kept in your browser's cache, so later runs work offline.
Which AI model does the vocal remover use?
HTDemucs (Hybrid Transformer Demucs) by Meta AI, released under the MIT licence, in a browser build for ONNX Runtime Web. It runs on your graphics card through WebGPU when available, otherwise on the CPU with WebAssembly.
How long does separating a song take?
On a GPU it is usually faster than real time. On the CPU expect roughly one to three minutes per minute of audio. A progress bar shows the time left and you can cancel at any moment.
Can I remove background music from my video?
Yes. Choose 2 stems, then save the vocals as MP4: your picture is kept unchanged and the soundtrack is replaced by the voice-only track. You can also save the instrumental to reuse the music.
What is the difference between 2 and 4 stems?
2 stems gives a vocals track and an instrumental track (everything except vocals). 4 stems splits the music further into drums, bass and other, which includes keys, guitars and synths.
Can I use it on any song?
Use it on recordings you made or have permission to use. Separating a track doesn't change who owns it, so publishing or selling stems of someone else's song still needs the rights holder's licence.
