Definitions Q to Quarter Track

 

Q

Quad (Quadraphonic)
A system of four channel sound where the channels are designated as left front, left back, right front, and right back.

Quadrophonic
A sound system which uses four independent speakers (or sets of speakers). The fore-runner of today’s Surround Sound. See Stereophonic.

Quality Factor
The ratio of reactance to resistance in a coil which affects Q.

Quantize
The conversion of the values of an analog wave or random occurrence into steps.
Quantization A quantizing (see above).

Quantization Distortion/Quantization Error
A modulation noise (also perceived as a distortion) that occurs in digital processing/recording caused by the sample levels being altered to conform to standard Quantization levels.

Quantization Levels (Quantizing Levels/increments)
A standard level that can be recognized by a digital recording system.

Quantization Noise
A modulation noise (also perceived as a distortion) that occurs in digital processing/recording caused by the sample levels being altered to conform to standard Quantization levels.

Quarter Track
A format in tape recording where each track takes up 1/4 of a quarter inch tape width.
