What (who) is array troops - definition

GROUP OF MICROPHONES OPERATING IN TANDEM

Large Microphones Array; Microphones array; Array microphone; Mic array

Dynamic array

RANDOM-ACCESS, VARIABLE-SIZE LIST DATA STRUCTURE THAT ALLOWS ELEMENTS TO BE ADDED OR REMOVED

Growable array; Dynamic table; Array list; ArrayList; Resizable array; Resizeable array; Arraylist; Mutable array

In computer science, a dynamic array, growable array, resizable array, dynamic table, mutable array, or array list is a random access, variable-size list data structure that allows elements to be added or removed. It is supplied with standard libraries in many modern mainstream programming languages.

Array (data structure)

DATA STRUCTURE

Ragged arrays; Array index; Vector data structure; Array element; Two-dimensional array; One-dimensional array; Vector (Computer Science); Static array; Array data structure; Vector (data structure)

In computer science, an array is a data structure consisting of a collection of elements (values or variables), each identified by at least one array index or key. An array is stored such that the position of each element can be computed from its index tuple by a mathematical formula.

Microelectrode array

DEVICES THAT CONTAIN MULTIPLE MICROELECTRODES THROUGH WHICH NEURAL SIGNALS ARE OBTAINED OR DELIVERED, ESSENTIALLY SERVING AS NEURAL INTERFACES THAT CONNECT NEURONS TO ELECTRONIC CIRCUITRY

Microelectrode Array; Multi-electrode array; Utah array; Michigan array; Multielectrode array

Microelectrode arrays (MEAs) (also referred to as multielectrode arrays) are devices that contain multiple (tens to thousands) microelectrodes through which neural signals are obtained or delivered, essentially serving as neural interfaces that connect neurons to electronic circuitry. There are two general classes of MEAs: implantable MEAs, used in vivo, and non-implantable MEAs, used in vitro.

Microphone array

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
Binaural recording
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
Robotic navigation (acoustic SLAM)

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.

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.

An array of 1020 microphones, the largest in the world until August 21, 2014, was built by researchers at the MIT Computer 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.
