Spherical Microphone Array

Spherical microphone arrays are used to capture three-dimensional sound fields, aiming to improve spatial audio recording and processing. Current research focuses on enhancing spatial resolution using techniques like physics-informed neural networks for upsampling and developing robust beamforming algorithms, often incorporating self-attention mechanisms, for applications such as speaker diarization. These advancements are significant for improving the accuracy of room acoustic modeling, enabling more realistic virtual and augmented reality experiences, and advancing applications in areas like aeroacoustics and musical instrument analysis.
