Echo Canvas wins first: browser-based spatial acoustics workbench
OpenAIDevs · x · 2026-08-26
Kevin Yang's Echo Canvas took first place in Developer Tools. This browser workbench lets users design scenes and hear how geometry, walls, and materials affect acoustics in real-time. Supporting both 2.5D and 3D modes, it uses GPT-5.6 for constrained generation and validation, rendering results locally via the Web Audio API to provide a fast, iterative acoustic 'wireframe' before committing to game engine pipelines.
