This effect adds light saturations to the input signal. As already mentioned, a saturation generates new harmonics based on the frequency content of the input signal. Therefore, the exciter effect is capable of generating high frequencies out of signals which lack them, as is sometimes the case with vocals which, though being in tune, don't "bite" enough. This effect gives these voices certain characteristics, such as brightness and definition. Sometimes an exciter will be used on an entire mix to balance out its frequency-content. Another use it has is in television and radio: sometimes adverts are passed through the exciter effect in order to brighten sound compared to the programmes.
The following is a sound to which an Exciter effect has been applied.
