How A Condenser Mic Works
Sound and acoustic engineering is incomplete without the existence of microphones. There may have been bigger and better inventions in the field of communication and telephony, but none can match that of a microphone. It is one of the most essential components of modern living. Life is practically impossible without microphones. Almost all modern communicating devices, whether it is the mobile phone, or the hearing aid, or tape recorders, or karaoke systems, or megaphones, or television and radio broadcasting systems would seize to exist, if it is not for microphones.
Different forms and types of microphones or mics are available, catering to different fields and personnel. Not all of these are meant to be used for recording, while some of them are exclusively made for doing so. There are dynamic microphones, condenser microphones, tube microphones, USB microphones, ribbon microphones etc. The most modern ones include laser microphone, liquid microphone, and MEMS microphone and so on. Each one of them is special in their own way, and is extensively deployed in a particular field of another.
Condenser mics is a very unique type of microphone. It possesses a diaphragm, which does the work of a capacitor's plate. The sound waves, on falling in the empty space between the diaphragms, change its frequency. Condenser mics are further sub-categorized into DC-biased condenser microphone and high frequency (or radio frequency) condenser microphones. The capacitor plate needs to be charged. But the charge has to be static and of a fixed value. It is this charged element or capsule that ensures sensible constancy of the audio frequency. The overall circuit is termed as the ‘follower' or the ‘impedance converter'. Newer models, though, can possess two diaphragms, ensuring better sound reception and recording standards.
Nowadays, smaller sized condenser microphone is also available, which makes mounting and recording work quite easy. Newer variety of condenser mic, the electret condenser microphone, is also available in the market, which deploys knowledge of electrostatics and magnetism in the conventional condenser mic circuitry. Due to its specifications, condenser mics are used in diverse field, ranging from karaoke microphones, to telephone transmitters, to high fidelity microphones for recording. Most of these mics are widely used in recording studios and laboratories. This is due to the fact that using condenser mics; one can produce an audio signal which is high in quality. The small size also ensures maximum accuracy and compactness. A condenser mic needs a source of power, which is wither provided by a small battery, or via inputs on the microphone, like a phantom powering system.

How to make a turn a store bought microphone into a shotgun mic?
anyone know any tricks to covert a regular store brand microphone into a shortgun mic for a filming project?
Put it in a tube of some kind. The further down the tube you place the microphone the more directional it will become. I am thinking of the tubes maps are stored in.
