Parametric EQ (Pro only)

The Parametric EQ effect either emphasizes or attenuates specific frequency ranges. Parametric EQ is useful for enhancing music, such as boosting low frequencies to bring up bass. Using this effect, you can enhance up to three different bands of the audio footage. As you adjust controls, a Frequency Response graph indicates the combined equalization curve you create. On the Frequency Response graph, Band 1 is red, Band 2 is green, and Band 3 is blue. You may find it easier to specify controls if you determine in advance the frequency-response curve you want.

Adjust the following controls for the Parametric EQ effect:

Band Enabled

Activates an equalization band and its controls.

Frequency

Specifies which frequency to modify. This frequency acts as the peak of the effect--the center of the bandwidth you specify.

Bandwidth

Sets the range of frequencies to enhance above and below the frequency specified under Frequency.

Boost/Cut

Specifies the amount of boost or cut applied to the amplitude of the frequencies inside the specified bandwidth. Positive values boost; negative values cut.

If you have audio with an unwanted sound (such as a beep from a forklift in the background), you can isolate and cut the frequency range of the beep to attenuate the sound. You may need to experiment with several settings to isolate the frequency range. To do this, set keyframes for different Parametric EQ properties, and then preview the audio. You can also apply the Audio Spectrum effect to a motion footage layer to see the magnitude of the frequencies in the range you define.
