USING ADOBE AUDITION 81 Effects reference These functions are listed in order from narrowest to widest. Narrower functions include fewer surrounding, or sidelobe, frequencies but less precisely reflect center frequencies. Wider functions include more surrounding frequencies but more precisely reflect center frequencies. The Hamming and Blackman options provide excellent overall results.

Unlike the Parametric Equalizer, the Graphic Equalizer uses preset frequency bands for quick and easy equalization. You can space frequency bands at the following intervals: • One octave (10 bands) • One-half octave (20 bands) • One-third octave (30 bands) Graphic equalizers with fewer bands provide quicker adjustment; more bands provide greater precision. Gain sliders Sets the exact boost or attenuation (measured in decibels) for the chosen band. Range Defines the range of the slider controls. Enter any value between 1.5 and 120 dB. (By comparison, standard hardware equalizers have a range of about 12 to 30 dB.) Accuracy Sets the accuracy level for equalization. Higher accuracy levels give better frequency response in the lower ranges, but they require more processing time. If you equalize only higher frequencies, you can use lower accuracy levels. If you equalize extremely low frequencies, set Accuracy to between 500 and 5000 points. Master Gain Compensates for an overall volume level that is too soft or too loud after the EQ settings are adjusted. The default value of 0 dB represents no master gain adjustment. Note: The Graphic Equalizer is an FIR (Finite Impulse Response) filter. FIR filters better maintain phase accuracy but have slightly less frequency accuracy than IIR (Infinite Impulse Response) filters like the Parametric Equalizer.

Graphic Equalizer effect
The Filter And EQ
> Graphic Equalizer effect boosts or cuts specific frequency bands and provides a visual
representation of the resulting EQ curve. Unlike the Parametric Equalizer, the Graphic Equalizer uses preset frequency
bands for quick and easy equalization.
You can space frequency bands at the following intervals:
•
One octave (10 bands)
•
One-half octave (20 bands)
•
One-third octave (30 bands)
Graphic equalizers with fewer bands provide quicker adjustment; more bands provide greater precision.
Gain sliders
Sets the exact boost or attenuation (measured in decibels) for the chosen band.
Range
Defines the range of the slider controls. Enter any value between 1.5 and 120 dB. (By comparison, standard
hardware equalizers have a range of about 12 to 30 dB.)
Accuracy
Sets the accuracy level for equalization. Higher accuracy levels give better frequency response in the lower
ranges, but they require more processing time. If you equalize only higher frequencies, you can use lower accuracy
levels.
If you equalize extremely low frequencies, set Accuracy to between 500 and 5000 points.
Master Gain
Compensates for an overall volume level that is too soft or too loud after the EQ settings are adjusted. The
default value of 0 dB represents no master gain adjustment.
Note:
The Graphic Equalizer is an FIR (Finite Impulse Response) filter. FIR filters better maintain phase accuracy but
have slightly less frequency accuracy than IIR (Infinite Impulse Response) filters like the Parametric Equalizer.
