Appendix A: "Audio Plugins"84
Used conservatively, the Exciter can brighten some types of audio. Add some
"air" to vocal, horn, hihat, or acoustic guitar. Exciter usually works best on
monophonic tracks. Exciter can sound distorted and aggravating if over-used.
Exciter can sometimes brighten old low-fidelity cassette tapes, by adding
some highs which do not exist on the tape.
Frequency:
The cutoff point for high-frequency distortion. It is best to
adjust Frequency to include only the top octave which is present in the source
audio. For instance, if a track has frequency content up to 5000 Hz, try a
Frequency setting around 2500 Hz. This will create new harmonics primarily
above 5000 Hz, where they are least likely to interfere with harmonics in the
original source audio.
Hi Freq Level:
The level of the extra harmonics. If Frequency is set
properly, this control will typically be in the –12 to +12 dB range. Excessive
use of this effect can sound very bad. Hi Freq Level should be adjusted for a
subtle effect.
