FloorSAV is a framework that enhances audio‑visual large language models (AV‑LLMs) by embedding a dynamic 2D floormap derived from 3D point clouds, camera trajectories, spatial audio cues, and object landmarks. The floormap is fed into the AV‑LLM as a synchronized stream with egocentric video, enabling the model to jointly reason over visual, auditory, and geometric information in a single inference. The authors also introduce SAVED‑Bench, a benchmark for spatial reasoning tasks, and show that FloorSAV improves AV‑LLM performance on both SAVED‑Bench and SAVVY‑Bench, with ground‑truth floormaps highlighting its potential.

The paper introduces HLR-AVSceneQA, a benchmark that tests audio‑visual large language models on a hear‑localize‑reason hierarchy, assessing recognition of sounds, localization in egocentric and allocentric views, and reasoning about their relation to the visual scene. It also presents HLR‑LLM, a model that adds a binaural spatial audio branch to a strong audio‑visual foundation and is trained with a curriculum including chain‑of‑thought supervision for multi‑step spatial reasoning. Experiments show that existing AV‑LLMs are limited in spatial grounding and relational reasoning, while HLR‑LLM markedly improves spatial audio‑visual scene understanding without hurting semantic perception.
