Webponents in a microphone array system is the so-called beamforming, which aims at recovering a desired signal from noisy observations with a spatial filter [12–15]. Circular arrays have drawn a signifi-cant amount of attention since, thanks to their symmetries, they can have a similar performance in different steering directions [16–18]. WebMar 1, 2003 · This microphone consists of a circular array with a radius of 1 meter using 288 microphone capsules whose output signals are combined into 24 channels using simple analog electronics. These 24 channels are captured using a multi-track computer interface and post-processed into 12 discrete reproduction audio channels. WebA uniform circular microphone array is used to overcome the ambiguities of linear arrays, however the underlying concepts (sparse component analysis and matching pursuit-based operation on the histogram of estimates) are applicable to any microphone array topology. high school musical 2 basketball
