Array microphones and signal processing within an ethernet-based AVB network

Abstract

Array microphones are frequently used in the field of speech signal applications. In this paper a use case for array microphones combined with signal processing and IEEE 802.1 AVB Ethernet-based audio signal transmission is presented. The proposed application is intended for conferencing systems. The array microphones with beam steering and sound source localization algorithm are used to span multiple speakers' recording areas. The benefit is the elimination of separate table microphones for the speakers.
