In music, an adjective referring to HARMONY and its principles. In ACOUSTICS, when a vibrating object, such as a string, is set in motion, it vibrates both as a whole, with a FREQUENCY called the FUNDAMENTAL, and, with lesser intensity, in sections as well. If these smaller lengths are integer fractions (1/2, 1/3, 1/4, ...) of the total length of the string, their frequencies of OSCILLATION are called harmonics, and are integer multiples of the fundamental.
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.
Literally, to hear with two ears. Opposite of MONAURAL HEARING. The fact that the ears are some distance apart allows the localization of sound by registering the slight differences in time, PHASE and INTENSITY of the sound striking each ear. Each of these parameters has a different area of effect, intensity being a major factor above 1500 Hz (see SOUND SHADOW), while PHASE DIFFERENCEs (which are equivalent to time differences) are used in localizing lower frequency sounds.
The psychological measure of the magnitude of a SOUND or SOUND OBJECT including its SPECTRUM (frequency and intensity), harmonic content, duration and spatial properties.
