Designing Near-Field MVDR Acoustic Beamfomers for Voice User Interfaces

Authors: Stanford-Jason, Andrew

AES Convention 139 · Paper 212 · October 2015

Abstract

We present an analysis and design recommendations for a reduced computational complexity minimum variance distortionless response(MVDR) beamforming microphone. An overview of MVDR beamforming is given then decomposed into a generalized implementation to aid mapping to a microcontroller with some discussion of optimizations for real-world performance.
