Probing Spatial Structure in Pretrained Audio Representations
Chuyang Chen, Sivan Ding, Adrian S. Roman +1
The paper introduces SARL, a benchmark for evaluating how pretrained audio models encode spatial information such as source direction and room acoustics, and analyzes the strengths…
Sensitivity Analysis of Generative Spatial Audio Metrics: A Study on Responsiveness, Smoothness, and Symmetry
Purnima Kamath, Adrian S. Roman, Koichi Saito +2
Evaluating generative spatial audio for First-Order Ambisonics (FOA) remains challenging due to a limited understanding of how metrics respond to changes in spatial parameters such…
Latent Acoustic Mapping for Direction of Arrival Estimation: A Self-Supervised Approach
Adrian S. Roman, Iran R. Roman, Juan P. Bello
Acoustic mapping techniques have long been used in spatial audio processing for direction of arrival estimation (DoAE). Traditional beamforming methods for acoustic mapping, while…
Generating Diverse Audio-Visual 360 Soundscapes for Sound Event Localization and Detection
Adrian S. Roman, Aiden Chang, Gerardo Meza +1
We present SELDVisualSynth, a tool for generating synthetic videos for audio-visual sound event localization and detection (SELD). Our approach incorporates real-world background i…
