Audio effects
Auto Filter
A resonant filter moved by an LFO or by the loudness of the input.

Add it to a track
Select the destination track, open Plugins, and choose Add Effect. Find this device in Library → Effects. Effects process the signal from the devices before them in the chain.
Controls
| Control | What to listen or look for |
|---|---|
| Listen | Auditions only the filtered signal; turning this off restores the stored wet/dry mix. |
| Type | Chooses low-pass, high-pass, band-pass, or notch filtering. |
| Cutoff | Sets the frequency where the filter acts on the sound. |
| Resonance | Sets the filter's resonance or bandwidth; higher values make a narrower, stronger emphasis. |
| LFO Amount | Sets the strength and direction of the oscillator's modulation of the filter cutoff. |
| Rate | Sets how fast the modulation cycle repeats. |
| Sync | Locks timing to the project tempo instead of a free-running time or rate. |
| Synced Rate | Chooses a musical note division for tempo-synchronized timing. |
| Shape | Chooses the waveform of the repeating modulation. |
| Stereo Phase | Offsets the modulation cycle between the left and right channels. |
| Env Amount | Sets how strongly the envelope moves the filter cutoff. |
| Attack | Sets how quickly the envelope follower responds to rising input level. |
| Release | Sets how quickly the envelope follower relaxes as input level falls. |
| Mix | Blends the original signal with the processed signal; 100% gives only the processed sound. |
| Slope | Sets how steeply the filter attenuates frequencies beyond its cutoff. |
| Drive | Pushes the signal into nonlinear processing, adding distortion and harmonics. |
| Env Source | Chooses peak or averaged signal level for the envelope follower. |
| LFO 2 | Sets the strength and direction of the oscillator's modulation of the filter cutoff. |
| Envelope Mode | Chooses continuous input-level following or a timed envelope triggered when the input crosses the threshold. |
| Threshold | Sets the level at which the dynamics processor starts responding. |
| Decay | Sets how quickly the triggered filter envelope approaches Sustain after its attack while the audio gate remains active. |
| Sustain | Sets the triggered envelope target while the input exceeds Threshold and the audio gate remains active. |
Work with this device
Start with a short passage that represents your material. Change one control at a time. Compare at a similar listening level, using the device's power control to bypass it. Save a version of the project before making a large change.
Current behavior
Envelope Mode selects continuous following or a triggered envelope. Threshold, Decay and Sustain belong to the triggered path. Read the selected mode before expecting every envelope control to affect the response. Listen temporarily auditions the filtered signal, then restores the stored mix.
