From Wikipedia, the free encyclopedia
A microphone array is a set of multiple
microphones operating in
tandem. This is shown to have 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
-
High fidelity original recordings
Typically, an array is made up of
omnidirectional microphones distributed about the
perimeter of a space, linked to a
computer that records and interprets the results into a
coherent form.
There are some implementation of microphones arrays that are
really big. At the
Massachusetts Institute of Technology, an array of 1020
microphones
[1] has been built.
Microsoft's
Windows Vista computer
operating system has built-in support for microphone arrays
for increasing the accuracy of its speech recognition feature,
letting users connect multiple microphones to a single system,
so that the inputs can be combined into a single, higher-quality
source.
