GUIDE / vocal remover online
What does vocal remover do?
A vocal remover estimates the vocal source and the remaining accompaniment from a mixed recording. SoundTools runs a four-source Demucs model locally, exposes the vocal prediction, and combines drums, bass, and other into the instrumental output.
FIELD NOTES / 01
A real local processor, not a decorative upload box
Demucs WebGPU runs after you choose a source and explicitly start the operation. The audio samples remain in browser memory; SoundTools does not send the selected media to an application endpoint.
Confirm that your browser supports WebGPU, then start the one-time model download and local chunked separation. Results remain available for preview and download only in the current tab. Closing or refreshing the page releases those temporary objects.
PROCESS / THREE STEPS

QUESTIONS / PRACTICAL ANSWERS
Questions about this tool
Answers based on the current browser processor—not promises about a future version.
01Is my audio uploaded for processing?
No. Audio samples stay in browser memory. The page may download a codec or model asset, but it does not send the selected file with that request.
02Why can the first run take longer?
This tool uses Demucs WebGPU. A browser may need to download and initialize that runtime before the first operation; later runs can reuse cached assets.
03Can I preview the result before saving?
Yes. Audio-producing tools expose local result players, while analysis and transcription tools show their detected data before download.
04What happens when the browser is unsupported?
The workbench reports the missing capability instead of uploading the media or pretending that processing is still running.
