Measuring the Spherical-harmonic Representation of a Sound Field Using a Cylindrical Array

ICASSP 2019accepted

This paper describes how to encode into a spherical-harmonic representation of a 3-D sound field using a cylindrical microphone array. The standard way to represent a sound field is to use higher order Ambisonics specified over a spherical region. If the sound field is instead measured using a cylin…

Trinicon-BSS system incorporating robust dual beamformers for noise reduction

Craig A. Anderson, Stefan Meier, Walter Kellermann, Paul D. Teal, Mark A. Poletti

ICASSP 2015accepted

In this paper, a method of adaptive noise suppression combining spatially robust fixed beamforming and the TRINICON blind source separation algorithm is presented. A multichannel sensor array is first processed using complementary fixed beamformers into maximum and minimum SINR channels. The channel…
