Design the sound around its job
An impact needs to identify what collided, how much force was involved and what happened after contact. Specify both materials: a boot hitting wood should not have the same ring as steel striking steel. Keep a light contact and a heavy collision in the same sound family without making every hit equally dramatic.
Prompt examples
single heavy stone block hitting concrete, hard initial crack, dense low body, brief grit scatter, dry isolated impact
small steel tool tapping a hollow metal panel once, precise bright tick, brief panel resonance, no repeated tapping
single gloved punch against a padded training target, compact cloth snap and low soft thud, no voice, no room echo
Make it work in the game
- Name both materialsDescribe the moving object and the surface it meets. Add hollow, solid, brittle or padded only when that quality changes the result.
- Create force tiersGenerate light, medium and heavy contacts separately. Judge their onset and resonance at similar playback levels before using volume to express force.
- Separate aftermathDebris, sliding and bouncing may need different triggers from the initial contact. Keep them separate when physics can change the outcome.
What to check before export
- Align the first clear transient with physical contact rather than with the start of the animation.
- Play a rapid sequence to detect resonances that pile up or make unrelated materials sound identical.
- Keep impact feedback distinct from a victim reaction; the same collision may happen without a character present.

Frequently asked questions
Why do all my impacts sound metallic?
The prompt may overemphasize sharpness or ringing. Name the actual materials and request a short dull or padded body when appropriate.
How do I handle different collision strengths?
Build a few force tiers and map them to your game's collision or damage states. Compare transitions between tiers so a small velocity change does not create an unrelated sound.
