Frequently asked questions
Answers for file support, processing and exports.
What file types can I upload?
MP3, WAV, M4A and FLAC files are supported in the studio flow. Files under 50 MB are recommended for faster local browser processing.
Can I use it whenever I need?
Yes. The homepage workflow does not require sign-up, does not show a daily timer or usage counter, and does not ask for payment.
Can I download both stems?
Yes. The workflow is designed for two stems: vocals and instrumental. Download options can include MP3 and WAV exports.
Does it use my device GPU?
When WebGPU is available, the separation workflow can use browser GPU acceleration. If WebGPU is not available, the page can fall back to WASM processing.
Is there a watermark?
No. Exports are clean files without a visible or audible watermark added by the tool.
