Patent ID: 8355909

Claim:
A system for controlling dynamic range of an audio signal, the system comprising: an automatic gain control element configured to receive an input signal having a varying level and to output: a control signal that varies based on the varying level of the input signal, and a modified input signal having a dynamic range different than a dynamic range of the input signal; an inverter in circuit with the automatic gain control element and configured to receive and invert at least one of: the control signal, or a block-based control signal corresponding to the control signal in block format; and a variable gain element configured to receive the modified input signal and at least some of the inverted at least one of the control signal or the block-based control signal, and further configured to output a remainder signal corresponding to the modified input signal as unmodified based on the at least some of the inverted at least one of the control signal or the block-based control signal.
