The paper proposes a hierarchical conditioning approach for joint Acoustic Scene Classification and Audio Tagging, predicting scene categories directly from intermediate event probabilities. Extensive experiments on three backbones and varied loss‑weighting settings show that this method matches or surpasses traditional multi‑head models while enabling synchronized dual‑task learning for certain beta values. An interpretability framework combining information bottleneck analysis, manifold geometry, and Formal Concept Analysis on TF‑IDF event representations demonstrates that hierarchical conditioning reduces conditional entropy, increases mutual information, and improves latent cluster separability, yielding a more structured and semantically faithful feature space.
arXiv:2605. 13672v1 Announce Type: cross Abstract: Few-shot classification (FSC) is widely used for learning from limited labeled data, yet most evaluations implicitly assume that target concepts are independent of contextual cues.
Recent Large Audio Language Models (LALMs) have achieved remarkable progress in audio perceptual tasks across individual acoustic layers, including speech, sound, and music. However, existing benchmarks predominantly evaluate these layers in isolation, overlooking the complex contextual relationships that arise when multiple acoustic sources co-occur in real-world auditory scenes.
UniAE-MoE is a unified audio encoder that uses a Mixture-of-Experts architecture to model cross‑domain audio representations. It integrates encoder components from Qwen2‑Audio and Audio‑Flamingo 3, enhances them with SwiGLU and shared experts, and applies a two‑stage instruction‑tuning strategy along with task‑specific data scaling. The model achieves state‑of‑the‑art results on the XARES‑LLM benchmark (0.802) and tops the Interspeech 2026 Audio Encoder Capability Challenge, demonstrating strong generalization across speech, music, and general audio tasks.

arXiv:2606. 29901v1 Announce Type: cross Abstract: Sound event detection (SED) is a core module for acoustic environmental analysis, yet its performance is often limited by scarce labeled data.
AVC-Reward introduces an event‑centric framework for evaluating audio‑video consistency, breaking down scenes into individual audio and visual events and assessing them at three levels: global narrative harmony, event‑level temporal synchronization, and fine‑grained attribute alignment. The metric, instantiated as a trainable reward model, is validated against human judgments using the AVC‑Benchmark, which contains diverse positive and negative samples from various generation models. AVC‑Reward outperforms existing automatic methods, offers interpretable failure localization, and enhances consistency when used as a reinforcement‑learning signal.
The paper introduces BEANS-Next, a comprehensive benchmark covering acoustic perception, biological category recognition, scene understanding, and in-context learning in bioacoustics, and shows that current audio‑language models perform poorly outside the narrow label‑centric tasks traditionally evaluated. To address this gap, the authors present ROOTS, a large‑scale training dataset enriched with curated real‑world data, behavioral and acoustic metadata, and synthetic generation, which improves performance across all BEANS‑Next task groups. Both the benchmark and dataset are released as open‑source resources to accelerate research in bioacoustics and ethology.
ViSSFlow is a unified flow‑matching framework that jointly tackles Video‑to‑Sound (V2S) and Visual Text‑to‑Speech (VisualTTS) generation. It incorporates a Diffusion Transformer with a disentangled condition aggregation mechanism, using cross‑attention for semantic cues and self‑attention for dense visual information. The authors also introduce a feature‑level data synthesis strategy to compensate for limited joint training data, and demonstrate that a single model can be trained end‑to‑end without sacrificing performance on either task.

arXiv:2607. 04383v1 Announce Type: cross Abstract: Large Audio-Language Models (LALMs) reason fluently about sound yet struggle to localize precisely when events occur, while classical Sound Event Detection attains frame-level precision only over a closed label set.
