When should I use Voice Conversion vs Transform Vocals?
When should I use Voice Conversion vs Transform Vocals?

Which stem-separation model should I pick?
Which stem-separation model should I pick?
Start with Vocuno’s advanced splitter or LALAL.ai (the widest custom-stem support — drums, bass, guitar, etc.). Moises, BandLab, and LANDR are worth trying when a mix separates poorly. Suno’s stem split is only available on tracks generated with Suno inside Vocuno.

The AI vocals don't line up with my instrumental. What can I do?
The AI vocals don't line up with my instrumental. What can I do?
Split the result with Stems to isolate the vocal, then give the vocal and your instrumental to Vai and describe the fix (“start the vocal at 0:12, lower it slightly, mix it over my beat”). Vai trims, shifts and re-mixes the two files without a new generation. Full walkthrough on the Add Vocals page.
Should I use the mobile app or the web app for these tools?
Should I use the mobile app or the web app for these tools?
The web app at vocuno.com. The mobile app is built for listening and quick song creation; the pipelines, Stems, Vai and the Studio are web features, and the web app gives the best experience for any multi-step work. It is the same account, library and credits either way.
