EchoCache: Energy-Guided Cross-Modal Caching for Efficient Audio-Driven Video Generation

EchoCache is proposed, an energy-guided cross-modal caching framework for efficient A2V generation that leverages audio time-frequency energy as a saliency anchor to guide latent-level cache updates and further introduces a dynamic timestep-latent caching mechanism with quantized cache management for joint efficiency a...
