ABSTRACT:
A sticky leveler utilizing a window detection technique to preserve the relatively small level changes of an audio signal. The sticky leveler includes a voltage controlled amplifier (VCA) and a sticky detector, where an input signal is received by the VCA for creating a variable gain path to the VCA output. The control output of the sticky detector is coupled to the VCA control input for controlling the VCA gain. The detection input of the sticky detector may be coupled to the input signal for generating a feedforward automatic gain control leveler. Alternatively the sticky detector may be coupled to the output signal of the VCA for generating a feedback automatic gain control leveler.
