FAQ
Do files stay private?
Yes. A file is only visible to the account that uploaded it and is never used to train a model. The uploaded file is deleted as soon as processing no longer needs it — usually within hours; results stay on the account for 30 days, then are deleted too.
Do I need an account?
Yes — passwordless magic-link sign-in. 25 free credits on sign-up.
How do credits work?
One wallet across every tool, no subscription. Each job shows its cost before it runs.
Which formats?
WAV, MP3 and M4A for audio; MP4 and common formats for the video tools.
The ear behind the tools
Behind Carmina, a sound engineer — twenty years in studios, dozens of records produced. The tools work the way he does: listen first, then adjust, in the right amount.
