Start with one clear event
Anchor collisions with a readable onset, material identity and believable decay. Describe the source, action, scale and perspective before adding style. Generate close alternatives instead of asking for several unrelated sounds in one prompt.
Prompt examples
large stone impact on concrete, hard initial crack, heavy low body, brief loose debris tail
small metal object impact, bright precise contact, two quick bounces, dry isolated foley
Make it work in the game
- Generate variationsKeep the core event stable and compare small changes in weight, material and distance.
- Edit for timingTrim silence and unwanted tails so the sound aligns with the visible action.
- Test in contextName both colliding materials when their combination matters.
Frequently asked questions
How do I create a impact sound effect?
Describe one precise event, its material or source, its scale and listener perspective. Generate several variations, then test the clearest option in the game.
How should I mix a impact sound effect?
Name both colliding materials when their combination matters.
Which file format should I export?
Use WAV for a lossless master or further editing. Use OGG when a smaller game-ready asset is more important, and audition the compression in context.
