Sound Design

Tencent’s Hunyuan lab introduces ‘Hunyuan Video-Foley,’ an AI system generating synchronized, realistic soundtracks for AI-generated videos. Addressing the challenge of subpar audio in AI video, Hunyuan employs a three-pronged approach: a massive, high-quality audio-video dataset; an AI architecture focused on visual-audio synchronization and contextual understanding via text prompts; and Representation Alignment (REPA) training for high-fidelity audio. Evaluations show improved audio quality, timing, and realism compared to other AI models, promising an enhanced and immersive viewing experience.
