What is a condenser microphone and how does it work?
A condenser microphone is a type of microphone that uses a capacitor to convert sound waves into electrical signals. It consists of a thin diaphragm and a metal backplate, which are separated by a small gap. When sound waves hit the diaphragm, it vibrates and causes a change in the capacitance between the diaphragm and the backplate, resulting in an electrical signal.
Condenser microphones are known for their high sensitivity and wide frequency response, making them ideal for capturing detailed and nuanced audio. They are commonly used in recording studios, live performances, and public speaking events. However, they do require an external power source, known as phantom power, to operate.
