Wawa-Lipsync is a new open-source JavaScript library that enables real-time lip synchronization for web applications. Unlike existing solutions that are either expensive or slow, this library analyzes audio frequencies in real-time to generate visemes (visual representations of phonemes) that can animate 2D or 3D characters. The library works by using the browser's analyzer node to detect audio patterns and deduce mouth movements, making it suitable for AI chatbots, games, and interactive web experiences without server-side processing delays.
