Equalize

This effect refines the tonal quality of an audio clip. It works similarly to the graphic equalizers found in consumer audio equipment. Adjustments are measured according to the percentage by which you boost or cut the original signal at the stated frequency band. If you require more precise equalization, see Parametric Equalization.

Flat Resets the equalizer to no adjustment on all frequency bands. Click to reset the clip to its original state.
