r-audio: Declarative, reactive and flexible Web Audio graphs in React
summary
r-audio is a React wrapper that maps Web Audio nodes to JSX components, providing supports all non-deprecated nodes and graph combinators (pipeline, split, cycle) so arbitrary directed graphs and live mutations are expressible as component trees. It exposes the internal AudioContext via a callback for creating buffers and AudioWorklets, offers an extensible subgraph class for reusable NPM-sharable modules, and ships demoed examples (gain matrix, delay line) that work. Early measurements show noticeably higher start/stop latency than native calls, so performance needs further profiling.
