Order Ambisonics

Order Ambisonics is a spatial audio representation using spherical harmonics to encode sound fields, aiming for accurate and immersive reproduction. Current research focuses on improving encoding and decoding techniques, particularly through neural networks for upmixing and binaural rendering, and exploring robust algorithms for direction-of-arrival estimation using various input representations like spherical intensity maps. These advancements are significant for enhancing virtual and augmented reality experiences, improving sound event localization in challenging acoustic environments, and providing a standardized framework for spatial audio processing.
