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
We listen to a cassette of spiritual music – Tibetan monks or Gregorian singing. If you listen carefully, you can hear how the voices merge, forming one pulsating tone.
This is one of the most interesting effects inherent in some musical instruments and the chorus of people singing in approximately the same key – the formation of beats. When voices or instruments converge in unison, the beats slow down, and when they diverge, they accelerate.
Perhaps this effect would remain in the sphere of interest only of musicians, if not for the researcher Robert Monroe. He realized that despite the widespread fame in the scientific world of the effect of beats, no one investigated their effect on a person’s state when listening through stereo headphones. Monroe discovered that when listening to sounds of close frequency on different channels (right and left), a person feels the so-called binaural beats, or binaural beats. Continue reading
