Add Vocals Tool

Try it now! ↗️
Add Vocals lets you bring an existing instrumental and have AI vocals sung on top of it. Upload your beat, add lyrics (or let Vocuno write them), pick a vocal gender, and you get finished songs with the new vocal mixed over your own track.

​
Engines

Each run returns two takes. There is no Fast or Clean mode to pick anymore.

​
Inputs

  • Instrumental: upload a file (MP3, WAV, FLAC, OGG, M4A, AAC) or import one from your library.
  • Custom lyrics: paste your own, tap Pick from Library to reuse saved lyrics, or use Optimize to polish them. With Vocuno you can leave the field empty and original lyrics are written for you. Suno needs lyrics.
  • Vocal gender: Female or Male.
  • Vocal description (Vocuno): optional, describe the voice and delivery you want.
  • Suno options: title, vocal prompt, style, negative tags, and sliders for style weight, weirdness and audio weight.

​
What you get

Each take lands in your library as its own card, ready to play, download or open. Open a finished take to:
  • Switch between Your Instrumental and Generated Song.
  • Mute, Solo or change the volume of each track.
  • Use Adjust timing to drag the vocal earlier or later against your beat, then Save version to render a new mastered mix.
  • Download the full song or the vocal on its own (paid plans).
The Advanced output section in the side panel also lets you download stems or a WAV file.

Frequently asked questions

MP3, WAV, FLAC, OGG, M4A and AAC. Cleaner instrumentals (no vocal bleed) give better results.
Yes. Paste them in, pick them from your saved lyrics, or write them with the AI lyrics generator first. With the Vocuno engine you can also leave lyrics empty.
The Vocuno engine works on instrumentals up to 4 minutes, and a longer file is refused before any credits are charged. Trim your file, or pick Suno for a longer track.
No. Open the take, use Adjust timing to nudge the vocal into place, balance the levels, and save a new version. No new generation and no extra credits needed.
Add Vocals runs on the web app. Use vocuno.com in a browser on your phone or computer. Your library and credits are shared, so anything you make there shows up in the mobile app too.
