The Envelope Follower creates auto-wah type effects. It works by following the envelope of the audio signal to control a filter or other type of effect.
Effect Variation - The type of envelope follower. Low pass filter (-24, -18, -12, -6 dB per octave ladder filter), high pass filter, band pass filter, notch filter, comb filter and pan.
Invert Envelope - Inverts the envelope.
Sensitivity - Controls how the envelope follows the signal. The LED indicates when it's fully opened.
Attack - The time it takes for the envelope follower to start working.
Decay - The time it takes for the envelope follower to stop working.
Depth - The amount the filter or effect is modulated by the envelope.
Filter Frequency - The filter's cutoff frequency.
Filter Resonance - The amount of filter resonance (feedback). For the notch filter, it controls the bandwidth.
Filter Overload - The amount the filter is overdriven.
