The ability to judge PITCH absolutely, without reference to another pitch or frequency. Also called absolute pitch. Perfect pitch appears to be an innate ability of some individuals, whereas related skills, such as remembered pitch or relative pitch which use other pitches as references, can be learned through musical practice.
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.
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.
(Greek: monos = one; phone = sound) A form of reproduction which records, transmits and reproduces the original sound along a single CHANNEL, regardless of the number of loudspeakers used. All components of the sound are combined or MIXed into one SIGNAL, including AMBIENCE and REVERBERATION, and therefore only the sense of depth may be simulated or reproduced.
