MUS 210 Chapter Notes - Chapter 5: Phantom Power, Cardioid, Digital Domain
Document Summary
A look through the recording path of audio. Once an instrument/voice has produced air vibrations, a transducer carries out the conversion of these acoustic vibrations into an analog electrical signal. Transducers convert energy from one form to another. Microphones convert acoustic energy into analog electrical energy. Preamps take the small signal from the mic and turn it into a larger one that can be digitized. Analog to digital converters (adc) turn analog electrical signals into digital electrical signals. The signal becomes a string of binary numbers (digital audio) and enters the digital domain (editing, processing, mixing) When digital audio is played back, it goes through a digital to analog converter (dac) which plays it back through speakers or headphones (converts digital audio to analog audio) The analog electrical signal is sent into an amplifier (makes the signal larger) and then to a transducer (speaker) to convert the electric energy back to acoustic.
