Sounds On The Web

This pulls audio feedback and synthesis rules from a larger UI/UX wiki covering 152 best practices across animations, CSS, typography, and interaction patterns. You'd reference it when adding sound to buttons, confirmations, or error states. The audio section is solid on accessibility (every sound needs a visual equivalent, respect prefers-reduced-motion) and Web Audio API implementation details like reusing AudioContext and using exponential decay for natural sound envelopes. It's opinionated about when not to add sound, which is honestly more useful than guides that encourage audio everywhere. The synthesis rules are brief but cover the basics of generating UI sounds with oscillators and filtered noise instead of loading files.
