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.
A TONE having more than a single FREQUENCY component. For instance, a tone consisting of a FUNDAMENTAL and OVERTONEs or HARMONICs, may be said to be complex.
A term used in broadcasting and recording to indicate a spatial movement of a SIGNAL. A sound is panned when it is moved smoothly from one location (e.g. LOUDSPEAKER or CHANNEL) to another. This is accomplished by using various ATTENUATORs or POTENTIOMETERs, sometimes combined into a single unit called a pan-pot or panoramic divider in order to control the AMPLITUDE of the signal in each channel.
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.
