Paper: How to Design a Delay-and-Sum Beamformer for Rigid Rotationally Symmetric Arrays?

Karim Helwani has presented a paper at the Asilomar Conference on Signals, Systems, and Computers on beamforming algorithms for microphone arrays with acoustically rigid surfaces. Principles from Wave Field Synthesis and time-reversal acoustics are used to derive computationally efficient and … Continue reading
