Final Cut Pro: 4 Audio Filters and What They Do
Final Cut Pro provides many audio filters. Audio filters can be used to clean up audio or to apply special effects to audio. All of the audio filters that are available in Final Cut Pro have parameters that can be manually edited. This guideline will go over the Noise Reduction filters and Echo and Reverberation filters that are available in Final Cut Pro.
1. Hum Remover
The Hum Remover filter is a Noise Reduction filter. The Hum Remover filter allows you to remove cycle hum from your audio. Cycle hum may have been added to your audio by a grounded wire in your recording setup.
2. Vocal DeEsser
Like the Hum Remover filter, the Vocal DeEsser filter is a Noise Reduction filter. The Vocal DeEsser filter is basically an equalization filter that allows you to reduce "ess" sounds that are sometimes created by microphones that have high frequencies. The Vocal DeEsser filter is unable to completely eliminate "ess" sounds from your audio.
3. Vocal DePopper
The Vocal DePopper filter is the final Noise Reduction filter that is available in Final Cut Pro. When someone speaks strongly into a microphone, a "P" sound is often added to the audio. The Vocal DePopper filter allows you to use keyframes to reduce the intensity of the "P" sound.
4. Echo and Reverberation Filters
There are no separate Echo and Reverberation filters in Final Cut Pro. Instead, a panel that contains sliders is available for the Echo and Reverberation filters. The Echo and Reverberation filters both have sliders for Effect Mix, Effect Level and Brightness. Feedback and Delay Time are only available for Echo, and Type is only available for Reverberation.
The Effect Mix slider allows you to determine how much of the original audio should be mixed with the audio that is being created by the filter. The Effect Level slider allows you to control how loud the echo or reverberation effect is. The purpose of the Brightness slider is to control the quality of the echo or reverberation. As you increase the Brightness slider, the intensity of the effect increases.
The Feedback slider dictates how long the echoes that are created by the filter lasts. If you increase the Feedback slider, the echoes will repeat more and more. That will force the echoes to interact with each other, which creates a complex series of echo effects. The Delay Time slider allows you to decide how much of a pause there is between each echo. The Delay Time is represented by milliseconds.
The Type pop-up menu is the only element that is not a slider in the Echo and Reverberation filters panel. The Type menu is only available for Reverberation. The Type menu allows you to tell Final Cut Pro what type of room the filter should try to reproduce. For example, you could select medium room or tunnel to reproduce the acoustic environment of that room in Final Cut Pro.
