Apple Final Cut Pro 7 - Manual (Page 964)

• Parametric Equalizer
All of the Final Cut Pro EQ filters use a combination of three controls. For example, the
Parametric Equalizer filter contains the following controls.
• Frequency: This slider lets you select the audio frequency you want to boost or attenuate.
The lowest available frequency varies from 10 Hz for the High Pass filter to 80 Hz for
the 3 Band Equalizer. The highest available frequency for all EQ filters is 20,000 Hz.
• Q: This slider adjusts the bandwidth of the filter resonance, whose frequency value has
been set with the Frequency slider.
• Gain: This setting controls how much you’ll be boosting or attenuating the specified
frequency range.
Gain Filter
Unlike other audio filters in Final Cut Pro, the Gain filter is applied automatically to selected
clips when you use the Apply Normalization Gain command.
Audio normalization amplifies an audio clip based on its peak (or loudest) value. For more
information about how to use audio normalization, see
“Raising Audio Levels Using Audio
Normalization and Gain.”
The Gain filter has a single parameter (also called Gain) measured in decibel (dB) units.
When the Gain parameter value is positive, the clip audio is amplified. When the Gain
parameter value is negative, the clip’s audio is attenuated. A Gain value of 0 has no effect.
