High frequency effects
Configure the Graphic Equalizer effect
To configure the Graphic Equalizer effect:
-
Do any of the following:
-
Click the 10 Bands, 20 Bands, or 30 Bands tab to specify how many frequency bands you wish to configure (use more bands if you want to exert control over more specific frequency ranges).
-
Use a scrubber to boost or reduce the amplitude of the associated frequency range (your adjustments will be reflected in the graph).
-
As an alternative to using the Effects tab of the scrubbers, select a frequency band in the Band drop-down menu, and enter an amplitude value in dB in the Gain field.
-
Click the Graph Actual Response button to produce a green line in the graph representing the actual frequency adjustment that your equalization will produce. Compare it to the requested frequency adjustment, shown in blue in the graph (Figure 6). Increase the value in the Accuracy field as needed and click the button again until you’re satisfied with the projected actual frequency adjustment.
Figure 6: When you click the Graph Actual Response button in the Graphic Equalizer window, a line is added to the graph to illustrate actual frequency response that will result from the current Accuracy setting.
-
Click the Set All to Zero button at any time to return all equalization settings to 0 (to bring the waveform back to its unequalized state).
-
Adjust the decibel value in the Range field to increase or decrease the amplitude range of the scrubbers.
-
Adjust the decibel value in the Master Gain field if you need to compensate for volume changes that may result from your EQ settings.
-
-
Click OK.
Apply the Amplify/Fade effect
To apply the Amplify/Fade effect in the Edit View:
-
Make a selection in the waveform.
-
Do one of the following:
-
Choose Effects > Amplitude > Amplify/Fade (Figure 7).
Figure 7: The Amplify/ Fade effect can be found in Effects > Amplitude.
-
Click the Effects tab in the Organizer window, expand Amplitude, and double-click Amplify/Fade. The Amplify/Fade window opens.
-
-
Do any of the following:
-
Check the DC Bias Adjust box to adjust an off-center waveform.
-
Enter a value in the Peak Level field to specify a maximum amplitude for the normalization process. Click Calculate Now to scan the waveform and normalize based on that value.
-
Check the Lock Left/Right box to lock all L and R scrubbers together so that their settings always match; uncheck it if you want to use the scrubbers separately.
-
Check the View All Settings in dB box if you want amplitude settings to appear as decibel values; uncheck it if you want the settings represented as percentages of the original wave-form values.
-
-
Configure the options specific to each tab (see the following tasks).
-
Click OK. The Amplify/Fade effect is applied.
Configure the Amplify/Fade effect
Configure the options specific to each tab. See the following:
Constant Amplification tab
-
In the Amplify/Fade window, click the Constant Amplification tab (Figure 8).
Figure 8: The Constant Amplification tab of the Amplify/Fade window.
-
Move the Amplification scrubbers, or enter values in the adjacent fields, to change the volume of the selected audio.
-
Go on to the next tab, or click OK.
Fade tab
-
In the Amplify/Fade window, click the Fade tab (Figure 9).
Figure 9: The Amplify/Fade window.
-
Use the scrubbers, or the adjacent fields, to choose amplitude values for Initial Amplification (the beginning of a fade) and Final Amplification (the end of a fade).
-
Check a button next to Linear Fades (for a smooth fade at a constant rate across your selection) or Logarithmic Fades (if you want a steeper slope at one end of the fade).
-
Click OK. The Amplify/Fade effect is applied.
Tip
The Fade In and Fade Out presets in the Amplify/Fade effect window can be handy when editing files originating from vinyl records or live performances. You’ll often want to fade LP clicks and pops or audience applause in and out at the beginning and end of such files, and these presets provide a quick and easy way to do it.
