A FEW GOOD QUESTIONS

Before you press play.

What can I upload?+

MP3, WAV, FLAC, and M4A with a single mono or stereo audio track. Current size and duration limits appear above the upload area. Files are validated after upload.

Will the stems be perfectly isolated?+

Separation is an estimate. Reverb, overlapping instruments, and compressed recordings can leave artifacts or bleed. Listen to your results before using them.

How long will my files be available?+

The upload area shows the configured retention period. Your task shows its exact deletion countdown. Download files before it expires; expired files cannot be recovered.

Why is the processing node offline?+

Processing runs on a dedicated GPU computer. Uploads pause while it is disconnected or draining. You can return when the node is online.

Do I need an account?+

No. This MVP uses a private browser session. Clearing cookies or changing browsers removes access. There is one unfinished task per session, plus hourly and daily limits.

Can I use the output commercially?+

Only upload audio you are authorized to process. The default engine uses MIT-licensed Kim Mel-Band RoFormer; the rights to the input music and resulting content remain your responsibility.
