The Detailed Explanation of Recording Microphone

- Sep 29, 2018-

The most common type of microphone is a dynamic (also called a moving coil) microphone. The dynamic microphone is wound around the magnet with a coil. When the sound impacts the film attached to the magnet, the coil vibrates, resulting in a voltage waveform similar to the audio waveform entering the microphone. This way, the recorder you are using can record these voltages. Dynamic microphones are generally rugged, relatively inexpensive, and capable of handling high level sounds. Therefore, this type of microphone plays a very important role as a "high power microphone" in the studio. It is suitable for almost everything in drum performance, background vocals, guitars and bass speakers. However, dynamic microphones often do not have a frequency response, and a condenser microphone appears.

The band microphone has a higher end frequency response than the dynamic microphone, but is susceptible to damage in terms of use and sound pressure level. Therefore, it is often used in instruments with higher frequencies but not very loud sounds, such as orchestral music. Capacitive microphones use only two plates, one of which vibrates due to a sound impact and creates a magnetic field between the two plates. Capacitive microphones feature a wide frequency response and deliver very realistic penetrating sound. However, condenser microphones require a separate power source and are expensive. Therefore, most small studios only buy one or two of these microphones, which are used at critical moments, such as lead vocals, room amplification, and so on.
