Document Summary
Think of sound recording system as a signal chain. Transducer: a device that converts acoustic energy into electrical energy or vice versa. Di erent mica have di erent transducers this determines whether it"s dynamic or condenser. Phantom power is needed for a condenser microphone to functions. Dynamic mics are sturdy and rugged but less sensitive. But it is also less system to handling sounds. Less frequency responses, but can handle higher sound pressure levels. Requires a shock mount, something to hold it, aka a boom or a shot gun. Has a sharp attack and quick decay when recording. Ribbon microphones are bidirectional, tend to add low frequencies. Cardioid are more unidirectional, but gets a little from the side. Hyper tend to only come from the front. Lavalier mics are really small and are hidden on the person. Sampling frequency: how accurate is the recording to the actual sound.
