Understanding Audio Filters in Final Cut Pro
Audio filters have many uses from special effects to cleaning up audio. Essentially, an audio filter helps in removing any unnecessary sounds in an audio. It is also used to reduce sound and add sound effects.
An audio filter is an important component in sound mixing and production, and it can change the way a track sounds from its original source. This is the reason why the audio filters in Final Cut Pro are necessary components in the program.
Audio Filters in Final Cut Pro
All the audio filters available in Final Cut Pro are nondestructive. This means that original content is not changed or revised during editing. This also means that the filters are only used on the clips, not on the media file itself.
There are essentially 5 categories of audio filters available in Final Cut Pro.
Categories of Audio Filters
The Equalization Audio Filter in Final Cut Pro is used to decrease or increase the strength of the signal of an audio within bands or selected frequency ranges. It is recommended though to decrease the frequency of an audio sound to eliminate any distortion. This filter in Final Cut Pro can also be used to minimize any noise in the background and create effects that can change the sound of the voice in an audio.
Each of the Equalization Filters in FCP uses a three-control combination. These EQ filters include band pass filter, DC Notch, 3 band equalizer, high pass and low pass filters, high shelf and low shelf filters, parametric equalizer and notch filter.
On the other hand, the Gain Filter is automatically applied on clips that are selected when the Apply Normalization Gain command is used. The Audio Normalization amplifies a clip based on its peak.
The Dynamics Filter includes the Compression/Limiter Filter, which reduces the dynamic range of the audio by attenuating areas in the signal to more than its threshold. The Compressor/Limiter Filter in Final Cut Pro allows you make adjustments on the range of an audio clip. This can result to having the loudest part of the audio reduced while the quieter part remains the same.
There are 3 noise reduction filters available in Final Cut Pro each with its own uses. The Hum Remover removes the cycle hum in your audio which is like a low buzzing sound captured in your audio clip. The Vocal DeEsser essentially emphasizes the "ess" sounds in an audio. The Vocal DePopper allows you to attenuate the "P" sounds that results from the puffs of breath.
The last category of filters in Final Cut Pro is the Echo and Reverberation Filters. The reverberation filter adds a reverberation effect, while the echo filter increases or decreases the echo effect in a track.
Using the Audio Filters
When using the Audio Filters in Final Cut Pro, remember that the filters are applied in a sequence. This means that the first audio filter you use will be the first filter and the resulting audio track will be used to apply to the next audio filter.
If you would like to use multiple filters in Final Cut Pro, the sequence in which the filters appear in the Filters tab will determine how the final clip will sound.Popular Cameras for High Quality Photos:
