Foley lives in the tiny details: what the object is, what it touches, and how close the listener feels. Use the library when you need something immediately, then refine with AI prompts by stating the action (drop, grab, slide), the surface/material, and the desired dryness or room tone. The goal is a readable transient for sync and a tail that matches the space without masking dialogue.
Name the object and surface
Foley changes dramatically with material and contact point. A "mug set-down" can be ceramic on stone, glass on wood, or metal on laminate—each has a different pitch, impact weight, and ring.
- Include both object and surface: "ceramic mug on granite" beats "mug sound."
- Call out size/weight: small, heavy, hollow, padded, rigid.
- If you want no ring, say "damped" or "muted impact."
Control transient and tail
For editorial, the attack is what sells sync, while the tail decides whether the sound feels close, roomy, or washed out. Prompting these details helps the foley sit under speech and music.
- Ask for a "crisp transient" for taps, clicks, and grabs that must hit the frame.
- Choose tail length: "short dry tail" for tight cuts, "longer decay" for lingering actions.
- Mention reflections when needed: "small room reflections" vs "no reverb."
Build believable movement passes
When a character moves, the sound is rarely one event—there's cloth, foot contact, and small prop bumps. A single cohesive pass can feel more real than many isolated one-shots.
- Combine elements in one prompt: footsteps + cloth rustle + occasional bag bump.
- Specify steadiness: "consistent pace" or "stop-start with pauses."
- Keep noise controlled: request "low hiss" and "no heavy low-end rumble."
Avoid common foley pitfalls
The wrong foley draws attention fast. Overly wide stereo, excessive room tone, or exaggerated high-end can make a scene feel fake even if the timing is correct.
- Avoid overly loud handling noise that masks dialogue consonants.
- Skip long reverbs unless the scene is clearly in a big space.
- Don't stack unrelated textures; keep materials consistent with what's on screen.
