Parametric EQ

The Parametric Equalizer is a set of four frequency-selective filters that allow for very precise changes in the frequency content of a sound signal:

Using the Parametric EQ

  1. Open the Sonic Foundry Parametric EQ dialog.

  2. Choose a preset from the Name drop-down list, or choose a filter from the Filter style drop-down list.

  3. Adjust the filter frequency:

  1. Drag the Amount fader to set the gain applied to the specified frequency band. This gain may be positive or negative.

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

  3. 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.
