As noise is usually more prevalent at higher frequencies, the harmonics are derived from a purer frequency band resulting in clearer highs. Harmonic synthesis involves the creation of higher order harmonics from the fundamental frequency signals present in the recording. Due to the varying nature, noise is reduced compared to static equalizers. Dynamic equalization involves variation of the equalizer characteristics in the time domain as a function of the input. For other uses, see Exciter (disambiguation).Īn exciter (also called a harmonic exciter or aural exciter) is an audio signal processing technique used to enhance a signal by dynamic equalization, phase manipulation, harmonic synthesis of (usually) high frequency signals, and through the addition of subtle harmonic distortion.
