The Filter effect provides an Envelope follower for controlling the Cutoff frequency. The Envelope section offers control over the envelope’s shape and depth of modulation.
Adjust the Attack control to set the time (10.0 ms to 10 seconds) it takes to respond to increases in the audio signal level.
Adjust the Release control to set the time (10.0 ms to 10 seconds) it takes to recover after the signal level falls.
Adjust the Depth control to determine how much the Envelope follower affects the Cutoff frequency.
