====Microphones====

While many webcams do have integrated microphones, you may wish to purchase a separate microphone in order to increase the quality of the audio being recorded. Microphones tend to come in two different form factors: headsets and stand alone. Microphones are grouped into how they pick up sound. The most common are unidirectional.  Unidirectional picks up sound from one or more small, focused areas whereas the uncommon omnidirectional picks up sound from nearly every direction.<ref>http://www.performing-musician.com/pm/apr08/articles/technotes.htm</ref><ref>http://www.performing-musician.com/pm/may08/articles/technotes.htm</ref><ref>http://www.performing-musician.com/pm/jun08/articles/technotes.htm</ref>

Microphone sensitivity, or gain, is measured in dB, or decibels.<ref>http://www.learningaboutelectronics.com/Articles/What-is-the-sensitivity-rating-of-a-microphone</ref><ref>http://www.dpamicrophones.com/en/Mic-University/Technology-Guide/How-to-read-microphone-specifications.aspx</ref>
