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
1. “Sound + color”?
The property of sounds to evoke color images has been noticed a long time ago. Much has been written about the color rumor of A. Scriabin, who saw musical sounds in color. The whole direction in art – color music – is based on this property of music sounds.
There is evidence that speech sounds, especially vowels, can also be perceived in color. A. Rimbaud even wrote a vowels sonnet, in which he so colored the sounds:
A is black; white – E; And – red; Y is green; Continue reading
My first patient became my first teacher.
A girl of 16 years old was brought to me – recently her condition was close to suicide. Her eyes looked inward, she was in a daze, the words she found with difficulty. The girl put the Lusher test, and, of course, the first color was chosen black.
Among hundreds of reproductions, she chose Pieta Michelangelo, where the tragic madonna looked at her dead son, and the mournful insensibility of her beautiful face resembled Chekhov’s words about the beauty of human grief.
Numbness, gray clothes, something monastic in the form of a girl aroused sympathy, a desire to help and revive this stone with music.
I played and asked what she liked.
The girl chose the Beethoven’s Eighth Sonata, where the sufferer got out of trouble in humility and complaint of the second part. Continue reading
