Audio/Video Glossary - Audio ExciterAn audio circuit available in high quality audio equipment, designed to recreate the harmonic content of an audio signal which was lost during video or audio tape duplication. Using the audio exciter to recreate the lost harmonic content, generates a sparkling audio sound. This effect is different from normal high frequency boosting which generates noise* and hiss* while improving the frequency response of the audio signal. Audio exciting is available only on special sound correction devices.
