The CMU-NVIDIA team won the DCASE 2024 Automated Audio Captioning (AAC) Challenge with a system that describes sounds in words using advanced AI technology. Their solution uses multiple audio encoders (like BEATs and ConvNeXt) to capture a wide range of sound features. This multi-encoder setup helps the system provide richer, more accurate descriptions of sounds. They also used a language model to refine and summarize the captions, making them clearer and more natural. A special three-step process, involving filtering and summarizing candidate captions, further improved the results. Their approach outperformed others by 10% in accuracy, demonstrating the power of combining multiple AI agents and advanced models for complex tasks like understanding and describing audio.
