BROOKS AUDIO DESIGN Equal Loudness Contours

A drawing of several curves showing how loud the tones of different frequencies would have to be played for a person to say they were of equal loudness.

Equalization
1) The process of adjusting the tonal quality of a sound. A graphic equalizer provides adjustment for a wide range of frequency bands, and is normally inserted in the signal path after the mixing desk, before the amplifier. See Feedback.
2) Any time the amplitude of audio signals at specific set of frequencies are increased or decreased more than the signals at other audio frequencies.

Brooks XS - 45 Bit
The smallest unit of digital information representing a single "0" or 1.

Hard Disk (Hard Disc)
A storage unit for digital data that has rigid disks coated with magnetic material in a housing that includes the drive mechanism.

Brooks GT 845 Cue
1) The signal fed back to the musicians through headphones.
2) To set the tape or disc so that the intended selection will immediately play when the tape machine or player is started.
3) A location point entered into a computer controlling the playback or recording of a track or tape.
4) In MCI brand tape machines, a term meaning the same thing as Sync Playback (where the record head is used as a playback head for those tracks already recorded).

Attenuation
A making smaller: reduction of electrical or acoustic signal strength.

Amp
1) An abbreviation of the term Amplifier (A device which increases the level of an electrical signal.
2) An abbreviation of Ampere (the unit of current).
3) An abbreviation of amplitude (the height of a waveform above or below the zero line).

Haas Effect
Simply stated, a factor in human hearing where delay has a much bigger effect on human perception of direction than level does.
