You can adjust the amount of noise reduction using the Attenuation slider. To get maximum noise reduction, set the slider to 100%. Setting the slider to 0% effectively passes the audio straight through with no change. Random Noise Reduction introduces a distinctive artifact which, while often less objectionable than the background noise, can be annoying to the listener. The Attenuation setting allows you to find the balance point where noise reduction is achieved without introducing too much artifact. Often an Attenuation setting in the range 50-75% produces a good result. 3.4.3 20-Band Graphic Equalizer Figure 8: 10-Band Graphic Equalizer The 20-Band Graphic Equalizer is used to reshape the spectrum of the output audio. The sliders allow attenuation of the audio energy in a series of adjacent frequency bands, with each band centered at the specified frequency. The lower the slider bar is moved, the more attenuation is applied in that frequency band. The attenuation value for each band is displayed beneath the slider, and specific attenuation values may be entered into these text boxes. Valid values are between 0 and 30 dB. To apply the filter, click the LED button so that the indicator “light” turns green. The buttons to the left of the slider array can be used to quickly adjust the slider array as a whole. The up and down arrow buttons can be used to nudge the overall slider shape up or down. The three "quick select" buttons configure the sliders into a flat, a highpass, or a lowpass shape. 3.5 OUTPUT AGC (AUTOMATIC GAIN CONTROL) 10
Figure 9: AGC The AGC (Automatic Gain Control) is a dynamic level processor applied to the final output, after all other processing. The AGC applies gain as needed to maintain a good audio level (approximately –12 dB). The gain applied by the AGC is limited by the Max Gain setting; regardless of the audio level, no gain greater than Max Gain will be applied. If the signal input to the AGC is already –12dB or greater, no gain will be applied. To apply the filter, click the LED button such that the indicator “light” turns green. You can adjust the maximum amount of gain applied to the audio selection by using the slider or by entering the amount in the Max Gain text box. 3.6 REPORT GENERATION The Report button (in the top left corner of the plug-in window) creates and opens a text file named “QEAS_Settings.txt” (for AS version) or “QEVST_Settings.txt” (for VST version) in Windows Notepad containing all the current plug-in settings. There is room in this report for the user to enter a project name and his or her initials. The user can chose to save or print the report. Note that each time the Report button is clicked, the “QEAS_Settings.txt” file in the C:\Program Files\QuickEnhance AS II folder will be overwritten. In order to save copies of the report files, be sure to save them to a different file name. The VST version will prompt the user for a new filename each time the Report button is clicked. 11

3.6 REPORT GENERATION<br />
The Report button (in the top left corner of the plug-in window) creates<br />
and opens a text file named “QEAS_Settings.txt” (for AS version) or<br />
“QE<strong>VST</strong>_Settings.txt” (for <strong>VST</strong> version) in Windows Notepad containing<br />
all the current plug-in settings. There is room in this report for the user<br />
to enter a project name and his or her initials. The user can chose to<br />
save or print the report.<br />
Note that each time the Report button is clicked, the<br />
“QEAS_Settings.txt” file in the C:\Program Files\QuickEnhance AS II<br />
folder will be overwritten. In order to save copies of the report files, be<br />
sure to save them to a different file name. The <strong>VST</strong> version will prompt<br />
the user for a new filename each time the Report button is clicked.<br />
