Exciter (from the English Exciter), also called a harmonic exciter (harmonic exciter), psychoacoustic processor (psychoacoustic processor), enhancer (enhancer) and acoustic exciter (aural exciter) is 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. Continue reading
The term binaural is derived from two Latin words: bina – two and auras – ear. The term “binaural hearing” refers to the ability of humans and animals to determine the direction to the sound source, wherever it is: left, right, front, back, bottom or top. When listening to stereo recordings, you can also determine the direction to the sound source, but only in one horizontal plane: left or right. In 5.1 systems (e.g. home theater), the back-front sound can still be determined, but the top-bottom is already problematic.
Ideally, to accurately determine the direction to the sound source, nature should have provided for us at least 6 ears – according to the number of all directions, but we only have two. Continue reading
