ADOBE AUDITION 151 User Guide Gain This is where you enter the exact value for the gain (measured in dB) being used in the chosen band. Graph Actual Response Because this is an FIR filter, the response may not actually match the desired equalization curve at lower accuracy levels. Press this button to see the actual response of the equalizer rendered in the window above the band sliders. Accuracy Entering higher accuracy levels (longer FIR filters) in this text box will give better frequency response in the lower ranges. Note: Higher values require more processing time, but you can use lower accuracy levels if you only want to equalize higher frequencies. If you are equalizing very low frequencies, you should probably raise the accuracy. Values between 500 and 5000 points work well. Range This field defines the range of the slider controls. Enter any value between 4dB and 180dB. As a comparison, standard hardware equalizers usually have a range of 30dB to 48dB. Master Gain After the EQ settings have been adjusted, the overall volume level might be too loud or too soft. You can compensate for this by entering an overall master gain to be applied to the resulting audio. The default value of 0dB represents no master gain adjustment. Presets Adobe Audition comes with several Graphic Equalizer presets. More information on presets can be found in the "Looking at the Work Area" chapter. Preview Press the Preview button to audition the current Graphic Equalizer setting before you apply it to the waveform. The selection is looped until you press the Stop button. Since Adobe Audition's Previews are dynamic, this gives you the opportunity to make and hear processing adjustments as the selection is continuously played. Graphic Phase Shifter The Graphic Phase Shifter lets you adjust the phase of a waveform by adding control points to a graph. The x-axis (horizontal edge) of the graph measures the waveform's frequency content, while the graph's y-axis (vertical edge) displays the degrees of phase to shift, with zero degrees representing no phase shift.
