Typical microphone applications for installed audio systems

In order to select a microphone for a specific application, and to apply it properly, it is first necessary to know the important characteristics of the sound source(s) and of the sound system.
Through the 1980s and 1990s there has been an unprecedented advancement of computer and digital signal processing (DSP) technology. Spawned by the introduction of personal computers and the compact disk, the electronic tools now exist to recreate the quality of real acoustic spaces, to create virtual rooms if you like.
It has long been known in audio circles that sound system performance in a closed space heavily depends on the acoustics of that particular space. The acoustics of that space depends in large part on the geometry of the room, materials, physical obstructions, and special design features.
