An enhancer, an exciter and a tube amplifier – what is common?

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 →
