A. The “Prompt Layering” Technique
Instead of one simple prompt, use Texture Words.
-
Basic: Footsteps on stairs
-
Pro: High-quality close-up foley, heavy leather boots on creaking oak stairs, dusty atmosphere, isolated, rhythmic, no reverb
-
Adding “isolated” and “close-up” prevents the AI from adding background noise.
B. The “Audio-to-Audio” Workflow (In your Editor)
In filmmaking, foley is rarely a “single shot.” Professional sound designers create a “composite.”
-
Generate three different versions of the same footstep.
-
Layer them in Premiere or DaVinci Resolve.
-
Shift one slightly to the left, one to the right.
-
Change the Pitch of one slightly down to add “weight.”
C. Use “Negative Prompting” (In your UI)
In your Gradio interface, try adding words like music, hum, hiss, static, white noise to the “Negative Prompt” if you see that option (or just keep the prompt very literal). This forces the AI to stay away from “musical” sounds.
