Microphones

A microphone, which was originally invented by Emile Berliner in 1877, is a
device which allows you to record voices or sounds and place them onto computers,
generally as a wav file. Microphones also can be used with other applications
such as a voice dictation program or a voice conference program.

While not all computers come with microphones, a microphone can be purchased at a
local retail store such as radio shack or any other retail store. When purchasing
a microphone, it is not always necessary to purchase a microphone capable of
recording extended frequencies as the normal human voice is only capable of going
so high or low.

While generally Microphones are a separate computer component, some manufacturers
are integrating the microphone into computers. Generally, integrated microphones
can be found on laptops and some desktop monitors. Integrated Microphones are
usually a small hole in front of the computer which when spoken into will record
your voice.
