ABSTRACT
Audio production is key to good video productions. In fact some people say that 80 percent of good video production is good sound. The audience can accept strange lighting, unusual color balance, and special lighting effects, but unnatural or distorted sound, or muffled dialog that is hard to understand will not be accepted by a person's audience and is always immediately apparent. Microphones work, as people's ears do, by picking up sound waves that pass through the air, or in some cases through other conductive objects such as hard surfaces. Microphones respond to sound frequencies of a very wide range. Frequencies are measured in Hertz (Hz), which is the number of cycles in the sound’s wavelength per second. Good mics will respond to sound from 20Hz, which is a low, deep, bass sound, all the way to 20,000Hz, which is a high-pitched sound like the high reaches of a violin.
