How to use the parametric equalizer.
You can find the Parametric Equalizer effect in the same tab as the Graphic Equalizer. Audio engineers like using parametric equalizers because they offer maximum control over tonal equalization. In Audition the equalizer appears as a horizontal line on a graph, with frequency running along the horizontal ruler or x-axis from 0Hz to 10kHz in evenly spaced octaves. Amplitude runs along the vertical ruler or y-axis, from -15dB to 15dB or from -48 to 48.
Make adjustments by moving the dots on the graph where you want them or typing your desired frequency and gain in the fields below the graph. The curve of the line will bend around that dot.
Adjust exactly the frequencies you want.
Adjust the Q/Width to determine the effect your boost or cut has on surrounding frequencies. The wider the Q, the more gradual the slope and more natural-sounding the cut. A very narrow Q will result in a steep slope and a more manipulated sound. If the overall volume level is too loud or too soft after you adjust the EQ settings, move the Master Gain slider for volume control.
Try the presets.
With selections including Beefy Snare, Old Time Radio, or Vocal Enhancer, you might find just what you need. Then customize it to perfect and optimize your sound.
Use high-pass and low-pass filters.
A high-pass filter cuts low frequencies and lets high frequencies pass through, while a low-pass filter cuts high frequencies. You can find presets for both in the Graphic Equalizer and Parametric Equalizer in Audition. Most people can’t hear much below 100Hz, so producers often set a high-pass filter there without changing the listening experience. Set a low-pass filter for the same reason, but avoid setting it below 4000Hz and cutting some clarity from people’s voices.
