The nature of the sound of tube amplifiers

Exciter (from the English Exciter), also called harmonic exciter (harmonic exciter), psychoacoustic processor (psychoacoustic processor), enhancer (enhancer) and acoustic exciter (aural exciter) – this is a processing device used for the harmonious synthesis of high-frequency signals, using thin harmonic distortion.

This harmonic synthesis consists in creating higher harmonics based on lower signal frequencies. Typically, noise is present in different frequency bands in unequal 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.

Initially, exciters were made on the basis of tube amplifiers, but now they exist in the form of digital processors.

Exciters and enhancers are used to change the tonal qualities of sound. But, unlike the equalizer, which Continue reading

Sound Perception and Compression
Traditional lossless compression methods (Huffman, LZW, etc.) are usually poorly applied to compressing audio information (for the same reasons as when compressing visual information). Some lossy compression methods are listed…
