Add Vocals Tool

Try it now! ↗️
Add Vocals lets you bring an existing instrumental and have Vocuno layer AI vocals on top. Upload your beat, paste or auto-generate lyrics, pick a vocal gender, and Vocuno produces a finished mix with vocals sung over your track.

​
Inputs

Drop in any instrumental (MP3, WAV, FLAC, OGG, M4A). BPM is auto-detected, and you can paste custom lyrics or hit the sparkle button to write them with AI. Pick a vocal gender (Female / Male) and pick a quality mode.

​
Fast vs Clean mode

Fast runs Suno on your beat with an optional vocal style prompt and returns a couple of finished mixes — quickest path. Clean generates vocal covers, isolates the vocals, and shows you previews; you then pick the best take and the AI voice (Audimee or MusicGPT) before the final mix is rendered.

​
When the vocals don’t sit right on your beat

If a finished mix comes back with the vocals landing in the wrong place, drifting off the beat, or sung over a section you didn’t want, you don’t have to regenerate from scratch. Stitch it together yourself in two steps:
  1. Split the result with Stems. Open the finished track in the library and send it to Stems (or pick the isolated vocal take directly from the Clean mode previews). You now have the vocal on its own, separate from your instrumental.
  2. Hand both files to Vai. Open Vai, drop in the isolated vocal and your original instrumental, and tell it what to fix in plain language, for example “trim the vocal so it starts at the first verse, lower it a little, and lay it over my beat”. Vai trims, shifts, fades, re-balances volumes and mixes the two tracks into a new file, and shows you the result as a card you can play, download, or open in the Studio for finer edits.
Because the vocal and the instrumental stay separate until the last step, you can iterate on timing and levels without spending credits on another full generation.
Add Vocals, Stems and Vai are web tools. If you are on the mobile app, open vocuno.com in a browser on your phone or computer for this workflow. Your library and credits are the same account, so everything you made in the app is already there.

Frequently asked questions

MP3, WAV, FLAC, OGG, and M4A. Cleaner instrumentals (no vocal bleed) give better results.
Yes — paste them in directly. Or use the sparkle button to call the AI lyrics generator.
Phase 1 generates and previews vocal takes. Phase 2 lets you pick which take and which AI singer to use before committing to the final voice conversion.
Vocuno auto-detects BPM from the upload so the generated vocals lock to your tempo.
Yes. Run the result through Stems to pull the vocal out on its own, then ask Vai to trim, shift and mix it back over your instrumental. See When the vocals don’t sit right on your beat above.
Add Vocals runs on the web app. For the best experience, use vocuno.com in a browser, which also gives you Clean mode’s take selection, Stems and Vai. Anything you upload or generate there shows up in the mobile app’s library too.
