Graphic EQ |
Graphic EQ is a powerful plug-in that allows you to tailor sound with pre-defined bands or a user-definable envelope graph. Graphic EQ is divided into three pages: Envelope, 10 band, and 20 band.
You
can create a rough representation of a filter with the 10- or
20-band page and then switch to the envelope page to fine-tune the
frequency spectrum.
Open the Sonic Foundry Graphic EQ dialog.
Choose a preset from the Name drop-down list.
Click the Envelope tab.
Adjust the envelope graph:
Drag the small boxes (envelope points) up or down. When the envelope is below the centerline, signals of the corresponding frequency level are attenuated. When the envelope is above the centerline, the signal is boosted.
To create a new envelope point, left-click on any point of the envelope.
To delete an envelope point, click it with the right mouse button, or double-click it with the left mouse button.
To move all envelope points, press Ctrl+A and drag when the envelope
has focus (the cursor will be displayed as a ).
Click
the Reset button
to reset the graph.
Choose a setting from the Accuracy drop-down list to determine a balance between filter precision and processing speed.
Low
precision is not recommended for performing very sharp filtering,
when filtering very low frequencies, or when using a high sample rate.
Drag the Output gain fader if you want to apply a gain after processing.
Faders
for high frequencies will be unavailable when working with files
that use low sample rates.
Open the Sonic Foundry Graphic EQ dialog.
Choose a preset from the Name drop-down list.
Click the 10-Band or 20-Band tab.
Drag the frequency-band faders to boost or attenuate the selected frequency band.
To quickly disable a band, set the gain to 0.0 dB by double-clicking the fader handle.
The frequency displayed at the bottom of the fader is the center frequency of the frequency band affected by the fader.
