Soft UI sound set

CC0 — Free for any use

Darker, gentler and short — for consumer, wellness and messaging apps.

Use it for: mobile apps, chat, meditation and habit trackers. Each role is chosen from its family (296 variants across 12 roles) by measured attack, tail and brightness, so the set sounds like one product. Swap any role with its alternates if a sound doesn't fit.
