Building Calm, ASMR-Style Physics Clips
Sound choice, note spacing, volume balance and pacing: the settings that make a clip relaxing instead of busy.
What Makes a Clip Calm
A relaxing clip is defined by what it leaves out: fewer sounds, spaced further apart, at a lower volume, with slower motion and a quiet picture. Build calm by removing, not adding. Most busy clips have too many notes, not the wrong ones.
Choose a Soft Sound
In Basics > Sound, set what bounces play. A soft song from the Song Library works well, and so does a gentle sound effect: set Bounces play to Sound effect and audition the library sounds, or upload your own short, clean sound (under a second, with no silence at the start) in Audio > Sound, MIDI & audio hub.
Key tips
- Avoid sharp, loud effects such as explosions or lasers for this style. Short, rounded sounds read as soothing.
Space the Notes Out
This setting matters most. In Rhythmic mode, Engine > Rhythmic mode settings > Min bounce spacing (0 to 1000 ms) sets the shortest gap between two sounding bounces. For a calm clip, 300 to 600 ms gives roughly two notes a second, around the point where a listener stops following the rhythm and starts finding it soothing.
Balance the Volumes
Audio on the rail starts with four sliders: Main volume, Bounce volume, Break volume and Background song volume. Bring Bounce volume and Break volume down so the hits sit under the music rather than on top of it, and keep Main volume at or below 1 so the platform does not squash the sound.
Key tips
- Export and listen on a phone speaker, not headphones. That is how the clip will actually be heard.
Slow the Motion
Slow motion comes from physics. In Basics > Common, set Gravity low (around 0.01 to 0.04) so the ball drifts, keep Bounciness at or just below 1 so energy bleeds off gently, and lower World speed (0.25 to 3) to slow the whole run. Speed build-up should stay at 0.
Keep the Picture Quiet
Match the visuals to the sound. Turn RGB rainbow lights off (cycling colours are stimulating, the opposite of the goal) and pick one or two colours. Use a dark, calm background, keep trails soft, and turn collision effects off or down. On a phone screen, a single bright ball on a dark background is the most restful image.
