The subjective impression of FREQUENCY, in the same sense that LOUDNESS is the subjective sense of the INTENSITY or AMPLITUDE of a sound. As such, pitch is a psychoacoustic variable, and the degree of sensitivity shown to it varies widely with people. Some individuals have a sense of remembered pitch, that is, a pitch once heard can be remembered and compared to others for some length of time; others have a sense of absolute pitch called PERFECT PITCH.
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.
If a sound is a complex of many TONEs of various FREQUENCY, AMPLITUDE and PHASE, repeating together in a basic CYCLE of definite frequency, the fundamental is the lowest frequency of this complex and corresponds to the unique PITCH heard in such a COMPLEX TONE.
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.
