Intro to AutoFilter in Final Cut Pro
AutoFilter is a versatile filter effect with several unique features. You can use it to create classic, analog-style synthesizer effects, or as a tool for creative sound design.
The effect works by analyzing incoming signal levels through use of a threshold parameter. Any signal level that exceeds the threshold is used as a trigger for a synthesizer-style ADSR envelope or a low-frequency oscillator (LFO). These control sources are used to dynamically modulate the filter cutoff.
AutoFilter lets you choose between different filter types and slopes, control the amount of resonance, add distortion for more aggressive sounds, and mix the original, dry signal with the processed signal.
For information about adding the AutoFilter effect to a clip and showing the effect’s controls, see Add Logic effects to clips in Final Cut Pro.
The AutoFilter window is divided into sections for Filter, Envelope, Distortion, LFO, and Out (output) controls. An extended controls section is also available.
Filter controls: Control the tonal color of the filtered sound. See AutoFilter Filter controls in Final Cut Pro.
Envelope controls: Define how the filter cutoff frequency is modulated over time. See AutoFilter Envelope controls in Final Cut Pro.
Distortion controls: Distort the signal both before and after the filter. See AutoFilter Distortion controls in Final Cut Pro.
LFO controls: Define how the filter cutoff frequency is modulated by the LFO. See AutoFilter LFO controls in Final Cut Pro.
Out (output) controls: Set the level of both the dry and effect signal. See AutoFilter output controls in Final Cut Pro.
