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.

What do you want to do?

Use the envelope graph

  1. Open the Sonic Foundry Graphic EQ dialog.

  2. Choose a preset from the Name drop-down list.

  3. Click the Envelope tab.

  4. Adjust the envelope graph:

Click the Reset button to reset the graph.

  1. 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.

  1. Drag the Output gain fader if you want to apply a gain after processing.

Use the 10- or 20-Band EQ

Faders for high frequencies will be unavailable when working with files that use low sample rates.

  1. Open the Sonic Foundry Graphic EQ dialog.

  2. Choose a preset from the Name drop-down list.

  3. Click the 10-Band or 20-Band tab.

  4. 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.

  1. 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.
