Appendix A: "Audio Plugins"82
The Hum Filter is not very useful for "buzz." Buzz contains high-frequency
hum harmonics caused by RF interference from fluorescent lights, electric
motors, or cheap light dimmers.
Sixty Hz line buzz can contain harmonics at 60 Hz intervals all the way into
the high frequencies (420, 480, 540, 600, 660, 720, 780, 840, 900 Hz, etc).
Since there are so many possible buzz harmonics in mid and high
frequencies, notch filters are not very practical.
Of Band-in-a-Box's current available audio tools, the Gate plugin is probably
the best tool for Buzz.
Enhancer
Dynamically brighten tracks while adjusting the relative balance of mid and
bass frequencies. The Enhancer is a "clean" effect which does not use
distortion.
The Enhancer can be more effective than High frequency EQ, for brightening
tracks. High frequency EQ boost can increase any hiss that might be in the
audio. The Enhancer boosts highs when the midrange frequencies are loud
enough to mask hiss in the recording, so an Enhanced track may sound less
noisy than an EQ'd track.
Audio recorded with a cheap microphone or transferred from cassette can
benefit from the Bass Balance controls.
The Enhancer processes audio in three bands, Bass, Midrange, and High
frequencies. The relative levels within the bass can be adjusted. The overall
