* '''Applied to''': Shows which plug-in the filter is applied to. The construction of the filter requires applying it to a signal with the same bandwidth. The determination of the associated plug-in/bandwidth is automatic. Deactivate the filter to reset. | * '''Applied to''': Shows which plug-in the filter is applied to.
