Adaptive Diagonal Loading using Krylov Subspaces for Robust Beamforming
Manan Mittal, Ryan M. Corey, John R. Buck +1
Reliable adaptive beamforming is critical for large microphone arrays operating in highly dynamic acoustic environments. In scenarios characterized by fast-moving talkers and inter…
Adaptive Diagonal Loading for Norm Constrained Beamforming
Manan Mittal, Ryan M. Corey, John R. Buck +1
Reliable adaptive beamforming is critical for large microphone arrays operating in highly dynamic acoustic environments. In scenarios characterized by fast-moving talkers and inter…
Adaptive Linearly Constrained Minimum Variance Framework for Volumetric Active Noise Control
Manan Mittal, Ryan M. Corey, Andrew C. Singer
Traditional volumetric noise control typically relies on multipoint error minimization to suppress sound energy across a region, but offers limited flexibility in shaping spatial r…
Beamforming with Random Projections: Upper and Lower Bounds
Manan Mittal, Ryan M. Corey, Andrew C. Singer
Beamformers often trade off white noise gain against the ability to suppress interferers. With distributed microphone arrays, this trade-off becomes crucial as different arrays cap…
Latent FxLMS: Accelerating Active Noise Control with Neural Adaptive Filters
Kanad Sarkar, Austin Lu, Manan Mittal +3
Filtered-X LMS (FxLMS) is commonly used for active noise control (ANC), wherein the soundfield is minimized at a desired location. Given prior knowledge of the spatial region of th…
Accelerating Audio Research with Robotic Dummy Heads
Austin Lu, Kanad Sarkar, Yongjie Zhuang +3
This work introduces a robotic dummy head that fuses the acoustic realism of conventional audiological mannequins with the mobility of robots. The proposed device is capable of mov…
