Exciter (from the English Exciter), also called harmonic exciter (harmonic exciter), psychoacoustic processor (psychoacoustic processor), enhancer (enhancer) and acoustic exciter (aural exciter) – a processing device used for the harmonious synthesis of high-frequency signals using thin harmonic distortion.
This harmonic synthesis is to create higher harmonics based on lower signal frequencies. Typically, noise is not present in different frequency bands in equal amounts, and harmonics obtained from a clean frequency band will be clearer. Less commonly, exciters (enhancers) are used to synthesize low-frequency harmonics in order to simulate deep bass.
Sound processed by an exciter becomes more “pure”, “transparent”, “voluminous”, “warmer” than the original, and also spatially more localized. All these properties are enclosed in quotation marks, since they are perceived by a person subjectively. Also, subjectively, this is similar to adding high frequencies, although an increase in level is barely measurable. Continue reading
From ancient times to the present day, musical art has undoubtedly been recognized by philosophers, musicians, and teachers as an indispensable means of developing the spiritual world of man. No art can compare with music by the power of emotional impact.
In ancient Greece, musical art was given the leading role in education. The great Aristotle emphasized not only the pedagogical, but also the therapeutic value of music, believing that music through catharsis removes heavy mental experiences.
Pythagoras believed that music, as a manifestation of cosmic harmony, can create in man the same internal order and harmony as in space. It is known that music also has a therapeutic effect on the human body. Hippocrates also used in his medical practice the influence of music on the sick. Continue reading
