Unit 25: Music Production Techniques Introduction For this report, I am going to talk about microphone theory and as well as technical specifications of microphones, mixing desks, sample rates, bit depth, and speakers/monitors. Equipment list Specifications Microphones: A microphone is a type of transducer that converts acoustic energy (voice, guitar, acoustic drums, piano) into electrical energy. In this report, I am going to talk about the different types of microphone, and what they are and how they work. These types of microphones are called condenser microphones and dynamic microphones. There are also types of microphones called capacitor, electret, liquid, carbon etc. Microphones are used in studios to record voices, guitars, …show more content…
Also, all condenser microphones have a capacitor (a component that has two plates with voltage between them) built-in to convert sound waves into electrical energy. Inside a condenser microphone, you’ll find components such as the Diaphragm (or the front plate), the back plate, a built-in battery. When a sound wave strikes the diaphragm, it causes a vibration within the diaphragm which then causes a change in capacitance within the capacitor, which also changes the voltage. In order to get the capacitor working, a voltage has to be sent through it, this can be done by simply turning on phantom power (48 volts) on the mixing desk or an audio interface. The voltage running through the capacitor will be amplified and for either performance or recording. Dynamic microphone: Just like the condenser microphone, dynamic microphones are frequently used in both recording studios and live. But dynamic microphones work differently, they work via what’s called an electromagnetic induction (production of voltage/electrical energy across a conductor using magnetism). Dynamic microphones are usually versatile and suitable for general-purpose use, and not very expensive to
