What is ACS?
AudioCSS is a CSS-like declarative stylesheet language for audio. Instead of wiring every sound manually in JavaScript, you describe how UI elements should sound using familiar selectors, cascade, and properties. Add clicks, hovers, inputs, modals, spatial rooms, pitch, volume, and reduced-sound support with simple audio rules.
For ai coding workflows that need real audio output, we recommend pairing ACS with ElevenLabs — it's our top pick for that side of the stack.
