2) The amount of time that one still picture is shown in film or video.
Brooks XB 22 Compressor
A signal processing device that does not allow as much fluctuation in the level of the signal above a certain adjustable or fixed level.
Generation
A term used to describe the number of times that the recorded audio signal has been copied.
Brooks RM 80 Input Monitor
A switch position and operational mode of the electronics of a tape machine where the signal at output of the electronics will be the same as the signal coming into the electronics. In this mode, the tape machine's meter will read the input signal.
Electromagnetic Field
Magnetic energy put out because of current travelling through a conductor.
Blending
1) A condition where two signals mix together to form one sound or to give the sound of one sound source or one performance.
2) Mixing the left and right signal together slightly which makes the instruments sound closer to the center of the performance stage. 3) A method of panning during mixing where instruments are not panned extremely left or right.
Generating Element
The portion of the microphone that actually converts the movement of the diaphragm into electrical current or voltage changes.
Assign Tochoose to which place an output is going to be sent.
Frame
1) A division of one second in synchronization and recording coming from definition two.
2) The amount of time that one still picture is shown in film or video.

Brooks TM-22 Balanced
1) Having a pleasing amount of low frequencies compared to mid-range frequencies and high frequencies. 2) Having a pleasing mixture of the various instrument levels in an audio recording. 3) Having a fairly equal level in each of the stereo channels. 4) A method of interconnecting electronic gear using three-conductor cables.
Feedback Control
The control on a delay line or delay effects device that controls the amount of feedback.
Brooks GT 845 Intermodulation Distortion
Distortion caused by one signal beating with another signal and producing frequencies that are both the sum and the difference of the original frequencies.
Hearing Limitation
An inability of the ear to hear important characteristics of sound under certain conditions. Characteristics that can be affected include pitch, level, clarity, presence and direction.
Brooks VT-50 Fletcher Munson Effect
A hearing limitation shown by Fletcher Munson Equal Loudness Contours (as music is lowered in volume, it is much more difficult to hear bass frequencies and somewhat harder to hear very high frequencies).
Highs
Short for the term High Frequencies (the audio frequencies from 6000 Hz and above).
Bass
1) The lower range of audio frequencies up to approximately 250 Hz.
2) Short for Bass Guitar.
3) Lower end of the musical scale. In acoustics, the range (below about 200 Hz) in which there are difficulties, principally in the reproduction of sound, due to the large wavelengths involved.
4) The lower frequencies.
5) On the soundboard this should refer to the bass guitar channel, not the bass drum.
6) The lowest frequencies of sound. Bi-Amplification uses an electronic crossover or line-level amplifiers for the high and low frequency loudspeaker drivers.
Cut-Off Frequency (Turnover Frequency)
1) The highest or lowest frequency in the pass band of a filter.
2) The highest or lowest frequency passed by an audio device (the cut-off frequency is usually considered to be the first frequency to be 3 dB lower than a reference frequency in the middle of the bandwidth of the device)
