Under imperfect conditions, a single microphone that is embedded in a laptop or monitor does a poor job of capturing sound. An array of microphones can do a much better job of isolating a sound source and rejecting ambient noise and reverberation. This paper provides guidelines for manufactures and developers to create integrated or external microphone arrays for Microsoft Windows Vista systems.
This information applies to the Windows Vista operating system.
