Underwater Acoustic Channel Library
Zhengnan Li, Mandar Chitre, Diego A. Cuji +4
The development of communication systems critically depends on realistic channel models, yet there are no widely accepted standards in the underwater acoustic communications commun…
MRMAD: A Multi-Round Multi-Audio Benchmark for Evaluating Acoustic Degradation Perception in Large Audio-Language Models
Yize Li, Ningyuan Yang, Sile Yin +6
Large audio-language models (LALMs) have shown promising progress in understanding speech, music, and general sound events, yet their ability to reason about how audio signals are…
A Switching Beamformer for Highly Non-Stationary Environments
Manan Mittal, Ryan M. Corey, John R. Buck +1
Adaptive beamforming is a cornerstone of array signal processing, yet its performance often collapses in the face of complex, rapidly changing interference. When interferers appear…
Time Segmented Beamforming via Dynamic Programming: Theory and Implementation
Manan Mittal, Ryan M. Corey, Diego Cuji +2
In dynamic acoustic environments with time-varying interferers, effective beamforming requires identifying stationary regions over time. The Capon beamformer, a whitened matched fi…
Online Segmented Beamforming via Dynamic Programming
Manan Mittal, Ryan M. Corey, Diego Cuji +2
In dynamic acoustic environments characterized by time-varying interferers and moving sources, effective beamforming requires accurately identifying stationary regions over time. T…
A Survey of Advancing Audio Super-Resolution and Bandwidth Extension from Discriminative to Generative Models
Ningyuan Yang, Yize Li, Diego A. Cuji +4
Audio super-resolution (SR), also referred to as bandwidth extension (BWE), aims to reconstruct high-fidelity signals from low-resolution (LR) or band-limited (BL) observations, an…
