As times changed and PC Pitstop grew, we transitioned to a software subscription model to not only provide better and more secure diagnostic and maintenance tests, but turn our focus towards computer security with PC Matic. May 29, 2011. I want to use my '4 Microphone Array System' Playstation Eye as a webcam, as my current webcam has broken. It's Namtai, not Logitech. I got it with the game 'Eye-pet' about 2 years ago. I've downloaded the 'Namtai Eye-toy Drivers', but it doesn't install anything? It just comes up as a ZIP file and when I try and open the ZIP file, it has loads of random stuff in the folder. What drivers do I.
A microphone array is any number of microphones operating in tandem. There are many applications:
Systems for extracting voice input from ambient noise (notably telephones, speech recognition systems, hearing aids)
Surround sound and related technologies
Locating objects by sound: acoustic source localization, e.g., military use to locate the source(s) of artillery fire. Aircraft location and tracking.
High fidelity original recordings
Environmental Noise Monitoring[1]
Typically, an array is made up of omnidirectional microphones, directional microphones, or a mix of omnidirectional and directional microphones distributed about the perimeter of a space, linked to a computer that records and interprets the results into a coherent form. Arrays may also be formed using numbers of very closely spaced microphones. Given a fixed physical relationship in space between the different individual microphone transducer array elements, simultaneous DSP (digital signal processor) processing of the signals from each of the individual microphone array elements can create one or more 'virtual' microphones. Different algorithms permit the creation of virtual microphones with extremely complex virtual polar patterns and even the possibility to steer the individual lobes of the virtual microphones patterns so as to home-in-on, or to reject, particular sources of sound. The application of these algorithms can produce varying levels of accuracy when calculating source level and location, and as such, care should be taken when deciding how the individual lobes of the virtual microphones are derived.[2]
In case the array consists of omnidirectional microphones they accept sound from all directions, so electrical signals of the microphones contain the information about the sounds coming from all directions. Joint processing of these sounds allows selecting the sound signal coming from the given direction.[3]
An array of 1020 microphones,[4] the largest in the world until August 21, 2014, was built by researchers at the MITComputer Science and Artificial Intelligence Laboratory.
Currently the largest microphone array in the world was constructed by Sorama, a Netherlands-based sound engineering firm, in August 2014. Their array consists of 4096 microphones.[5]
Soundfield microphone[edit]
The soundfield microphone system is a well-established example of the use of a microphone array in professional sound recording.
