The Far-Field Equatorial Array for Binaural Rendering

Jens Ahrens, Hannes Helmholz, David Lou Alon, Sebastià Vicenc Amengual Garí

ICASSP 2021accepted

We present a method for obtaining a spherical harmonic representation of a sound field based on a microphone array along the equator of a rigid spherical scatterer. The two-dimensional plane wave de-composition of the incoming sound field is computed from the microphone signals. The influence of the…

Evaluation of Sensor Self-Noise In Binaural Rendering of Spherical Microphone Array Signals

Hannes Helmholz, Jens Ahrens, David L. Alon, Sebastià Vicenc Amengual Garí, Ravish Mehra

ICASSP 2020accepted

Spherical microphone arrays are used to capture spatial sound fields, which can then be rendered via headphones. We use the Real-Time Spherical Array Renderer (ReTiSAR) to analyze and auralize the propagation of sensor self-noise through the processing pipeline. An instrumental evaluation confirms a…
