Frequently asked questions
Are my files uploaded to a server?
No. Everything is processed entirely inside your browser. Your files never leave your device or get sent anywhere.
How is this different from the instant vocal remover?
The instant tool uses fast stereo math — approximate, but done in seconds. This tool runs the Demucs AI model for real source separation: clean vocals, drums, bass and instruments. It takes a few minutes per song and downloads a ~172 MB model once.
How long does it take?
After the one-time model download, expect a few minutes per song depending on your device. Keep the tab open and in the foreground. A computer works much better than a phone.
What do I get?
Four studio-grade WAV stems: vocals, drums, bass, and other instruments — each with its own player and download button.
