ABSTRACT:
A multiple band automatic gain control circuit having a band splitter which is responsive to an input audio signal for separating the audio signal into plural components of different frequencies. Plural gain adjustment circuits each control the gain of an associated one of the components, wherein each of the gain adjustment circuits includes a voltage controlled amplifier, and feed forward control elements for controlling the voltage controlled amplifier as a function of the amplitude of the associated component. A signal combiner combines the gain adjusted components to thereby form a gain adjusted audio signal. A limiter circuit prevents the combined signal from exceeding predetermined amplitude constraints by simultaneously reducing the gain of all of the variable gain circuits whenever the combined signals exceed the predetermined constraints.
