The property of an electric circuit by which a varying current in it produces a varying magnetic field that introduces voltages in the same circuit or in a nearby circuit. It is measured in henrys.
Far Field
The area from 3 feet away from the sound source up to the critical distance.
Brooks Speakers Decibel (dB)
1) Relative measurement for the volume (loudness) of sound. Also used to measure the difference between two voltages, or two currents. See Zero dB.
2) A numerical expression of the relative loudness of a sound. The difference in decibels between two
sounds is ten times the common logarithm of the ratio of their power levels.
DC
Abbreviation for direct current.
Brooks SS 81 Dynamic Mic
Robust type of microphone which picks up the sound on a diaphragm connected to a coil of wire which moves within a magnet. An alternating current is induced into the wire which provides the electrical output. Most dynamic mics have low output impedance of 200 Ohms. See Condenser Mic.
Generation
A term used to describe the number of times that the recorded audio signal has been copied.
Bouncing
Alternate name for Ping-Ponging (playing several tacks with sync playback through a console to mix them together and record them on an open track).
Console
A set of controls and their housing, which control all signals necessary for recording and mixing.
