Patent ID: 7024006

Claim:
A method of processing signals comprising: Providing a first signal and a second signal, each of said first and second signals comprising a frequency spectrum including a plurality of frequency bands; Supplying said first and second signals to first and second signal processors, respectively; Selecting at least one of said plurality of frequency bands with said first signal processor and selecting at least one of said plurality of frequency bands with said second signal processor, wherein said selections are less than the frequency spectrum of the plurality of frequency bands for said first and second signals; Adjusting the level of the first and second signals prior to providing said first and second signals to said signal processors; and Adjusting a level for the at least one frequency band selected by said first processor with said first processor, and adjusting a level for the at least one frequency band selected by said second processor with said second processor, such that an increase in level of said selected at least one frequency band in one of said first and second signals results in a decrease in level of said selected at least one frequency band in the other of said first and second signals, and said increase in level and said resultant decrease in level are performed independently of changes to other frequency bands in said first and second signal processors.
