The pick-up member includes a first pick-up unit, a second pick-up unit separated from the first pick-up unit by a first distance, and a third pick-up unit separated from the second pick-up unit by a second distance; the first distance is greater than the second distance. The first pick-up unit, the second pick-up unit and the third pick-up unit respectively receive the sound source and output an analog signal. The A/D conversion unit and the digital signal processor process the analog signals, and convert them into a directional digital acoustic signal. Thus, the directional digital acoustic signal has a maximum pick-up frequency. Thereby is decreased grating lobes and spatial aliasing.

Abstract: A method and system for metering and analyzing usage and performance data of virtualized compute and network infrastructures is disclosed. The processing functions of the metered data are divided into “processing units” that are configured to execute on a server (or plurality of interconnected servers). Each processing unit receives input from an upstream processing unit, and processes the metered data to produce output for a downstream processing unit. The types of processing units, as well as the order of the processing units is user-configurable (e.g. via XML file), thus eliminating the need to modify source code of the data processing application itself, thereby saving considerable time, money, and development resources required to manage the virtualized compute and network infrastructure.
