Hear the World in Stereo: Learning Dynamic Spatial Correspondence for Immersive Joint Video-Audio Generation

The paper introduces StereoBind, a framework that links visual source motion to stereo audio generation, addressing the need for dynamic spatial correspondence in immersive applications like AR/VR and gaming. It employs three mechanisms—Visual Motion Binding, Spatial Track Encoder, and Residual Track RoPE—to coordinate visual motion with stereo sound. The authors also present StereoWorld-29K, a large-scale dataset with paired motion tracks, and StereoWorldBench for evaluating audiovisual spatial consistency, demonstrating that StereoBind improves spatial alignment while maintaining overall quality.

SAVU-BENCH: A Real-World Benchmark for Spatial Audio-Visual Understanding

SAVU-Bench is a real‑world benchmark designed to evaluate spatial audio‑visual understanding across three capability levels and seven tasks, addressing limitations of prior simulated‑scene datasets. It includes a diagnostic set, SAVU‑Diag, that breaks down reasoning questions into grounding and alignment sub‑tasks, revealing that many errors stem from failures in these prerequisites. A training‑free baseline, SAVU‑EA, improves spatial grounding and joint matching but high‑level reasoning remains difficult, underscoring the need for better audio perception and cross‑modal spatial integration.

PRISM-Bench: An Audio-Centric Diagnostic Benchmark for Text-to-Audio-Video Generation

PRISM‑Bench is an audio‑centric diagnostic benchmark for text‑to‑audio‑video generation, built from 900 human‑verified samples. It evaluates audio along two axes—audio type (speech, music, sound) and sound‑source visibility (on‑screen vs. off‑screen)—across four perceptual dimensions (audio‑visual coherence, audio quality, audio expressiveness, and prompt following) using 35 fine‑grained criteria. The benchmark employs an enhanced MLLM‑as‑a‑Judge protocol that aligns strongly with human raters, revealing a performance gap between frontier and open‑source T2AV models and highlighting overfitting to perceptual fidelity while struggling with complex grounding and control tasks, especially for music and synchronized on‑screen audio.
