A recent development where, in contrast to the conventional analog TAPE RECORDER, the audio SIGNAL is sampled within a set of pre-defined limits. It is thus the reciprocal process to that described as digital SOUND SYNTHESIS. Digital sampling is also used is some digital SOUND SYNTHESIZERs.
(German: artificial head). A STEREOPHONIC recording system developed in Germany which employs an artificial head sitting on a resonator similar to a chest cavity. The recording MICROPHONEs are situated within the head, inside an anatomically correct ear canal, at the point where the human eardrum is located. Artificial PINNAE are carefully designed for accurate reflection of the incoming sound in order to achieve the good front-back and height-depth perspective for which the technique is noted.
Any FREQUENCY in the audible RANGE, usually between 20 and 20,000 Hz, and often referring to the frequency of AUDIO signals. Also called the audio spectrum.
The most commonly used medium for recording sound. It is manufactured in various widths (1/4, 1/2 and one inch primarily) and thicknesses (3.0, 1.5, 1 and .5 mil where 1 mil = 1/1000 inch) for different purposes, which now include video and digital recording.
