Envelope filter (Auto-Wah) inspired by Mu-Tron III. A resonant filter whose cutoff frequency follows the input signal's amplitude.
An envelope filter detects the amplitude of the incoming audio and uses it to sweep a resonant filter's cutoff frequency. Playing harder pushes the filter higher, creating expressive wah-like effects without a foot pedal. The Mu-Tron III, famously used by Stevie Wonder and Jerry Garcia, is the quintessential example of this effect.
Bypasses the module processing when activated (ON).
Audio input flow(s).
Audio output flow(s).
How much the input envelope affects the cutoff frequency. Higher values produce more dramatic filter sweeps.
Envelope attack time in ms. Controls how quickly the filter responds to transients.
Envelope release time in ms. Controls how quickly the filter returns to the base frequency after the input level drops.
Base cutoff frequency in Hz. The filter starts from this frequency and sweeps upward according to the envelope.
Filter resonance in %. Higher values create a more pronounced peak at the cutoff frequency, producing a more vocal, quacky character.
Filter mode selector: low-pass, band-pass, or high-pass. Low-pass gives the classic wah sound; band-pass is more vocal; high-pass produces thinner, more cutting sweeps.
Dry/wet blend. 0 = dry (unprocessed input), 1 = fully filtered.

Free multi-line text attached to the module, saved with the patch. It is only meant as an internal note for the patch designer: it is not displayed in the interface.
visible only in god mode, see setup-panel-tab-expert.
Read-only, not saved. Current private numeric ID of the object, used internally to identify it (for example as the target of a bind ID).
Read-only, not saved. Private ID used to store and recall the values of this control in presets.
Button. Generates a new unique ID, original ID and preset ID for the object. Use it if you experience difficulties in Polyphonic mode or if two objects share the same ID. Preset values and binds referring to the old IDs are lost.
Read-only, not saved. Absolute address of the object in the Usine objects tree, built from the workspace root. This is the address to use to reach the object from scripts, the objects panel or remote messages. Only shown for objects that are registered in the objects list. See objects-address.
Read-only, not saved. Address of the object relative to the current patch, valid inside that patch only. See objects-address.
Free user-defined address for the object (empty by default). When set, the object is also registered in the objects tree under this name, so it can be reached independently of its position in the workspace (the value is also reported in the mouse-over and mouse-down chunks). Changing it rebuilds the objects list. Only available on objects that support a user address. See objects-address.
