The Audio Beamforming System. Our audio beamforming system consists of a loudspeaker array with each speaker in the array controlled by a digital signal processor (DSP). The DSP uses a FIR filter and other signal processing algorithms to control the loudspeaker output. Our challenge was to identify the FIR filter coefficients that would produce ...
Spatial Signal Processing (Beamforming)

• In beamforming, the angular (directional) spectrum of a signal is revealed by Fourier analysis of the way sound excites different parts of the set of transducers. • Beamforming can be accomplished physically (shaping and moving a transducer), electrically (analog delay circuitry), or mathematically (digital signal processing).

Beamforming microphone arrays are always circular and come in three main patterns: random, spiral, and ring. (In contrast, NAH microphone arrays are always rectangular.) The ring array performs well when the exact distance to the source is unknown, but it lacks dynamic range. The spiral array gives better results, but you can generally achieve the
