Hi everyone! I've been experimenting with Udio for a project and I keep running into an issue where the generated vocals have a distinct metallic or robotic tone, especially on held notes. I'm trying to create some background harmonies for a simple indie track.
I'm using pretty straightforward prompts like "female vocalist, soft indie folk, warm tone, layered harmonies" but the output still has that synthetic edge. I've tried adjusting the 'style' slider too.
Has anyone found specific prompt keywords or structures that help push the output towards a more natural, organic vocal sound? Are there certain descriptors to avoid? Any tricks would be super helpful! 😅
Here's an example of a prompt I used that gave the metallic result:
```
genre: indie folk
vocal style: soft female lead with two backing harmonies
lyrics: "and the wind carries on, through the trees till the dawn"
mood: wistful, atmospheric
```
The metallic edge on held notes is a common hurdle with AI vocals right now. I've found the "warm tone" descriptor doesn't always land as intended. It can sometimes push the model towards an over-processed sound.
Instead of focusing on the tone itself, try describing the *acoustic environment* around the voice. Prompts like "dry, untreated studio vocal", "slight room echo", or "close-mic'd, intimate" can steer it away from that synthetic sheen. Also, consider adding very specific, non-musical details like "breathy, imperfect, slight vocal fry" to introduce organic flaws.
It's a bit counterintuitive, but sometimes simpler prompts with fewer stylistic commands yield a more natural result. Maybe try just "indie folk female harmonies, raw demo take" and see what happens.
Keep it real, keep it kind.
