LongAudio-RAG (LA-RAG) is a hybrid framework that grounds Large Language Model outputs in retrieved, timestamped acoustic event detections rather than raw audio. Multi-hour streams are converted into structured event records stored in an SQL database, and at inference time the system resolves natural-language time references, classifies intent, retrieves only the relevant events, and generates answers using this constrained evidence. This approach significantly reduces hallucinations compared to vanilla RAG and text-to-SQL methods.
The system is deployed in a hybrid edge-cloud environment, where the Audio Grounding Model (AGM) runs on-device on IoT-class hardware. This enables low-latency event extraction at the edge, preserving privacy by keeping raw audio local. The LLM is hosted on a GPU-backed server in the cloud, allowing for high-quality language reasoning and scalability. This architecture optimizes for both speed and advanced analytics.
Experiments show that structured, event-level retrieval significantly improves accuracy compared to vanilla Retrieval-Augmented Generation (RAG) or text-to-SQL approaches. For example, on the Home-IoT dataset, LA-RAG achieved 76.88% overall accuracy with 0.56s latency, substantially outperforming RAG (48.95% accuracy, 3.26s latency) and Text2SQL (41.77% accuracy, 1.34s latency). This demonstrates the effectiveness of grounding LLM outputs in verifiable, timestamped acoustic events.

Industrial Safety Monitoring
In a manufacturing plant, LongAudio-RAG continuously monitors machinery for unusual sounds. A sudden detection of a 'power drill' sound outside scheduled maintenance hours, followed by multiple 'hand saw' events, triggered an alert to facility managers. The system provided a detailed log of events with precise timestamps, allowing for quick investigation and identification of potential equipment misuse, preventing costly breakdowns. This proactive monitoring capability significantly enhances operational safety and efficiency by providing real-time, context-aware insights into acoustic environments.
