METHOD FOR EXPANDING AN AUDIO MIX TO FILL ALL AVAILABLE OUTPUT CHANNELS.

摘要

AUDIO SOURCES IN TYPICAL COMPUTER SYSTEMS PROVIDE DIFFERENT NUMBERS OF CHANNELS OF AUDIO SIGNALS TO A MIXING COMPONENT OF THE OPERATING SYSTEM. THIS CONVENTIONAL ARRANGEMENT USUALLY PREVENTS THE AUDIO SIGNALS FROM ALL SOURCES FROM BEING PLAYED BACK THROUGH ALL OUTPUT CHANNELS. NOVEL ARRANGEMENTS OF UPMIXING AND MIXING COMPONENTS ARE DISCLOSED THAT ALLOW AUDIO SIGNALS TO BE DELIVERED TO ALL OUTPUT CHANNELS REGARDLESS OF THE CONFIGURATION OF THE AUDIO SOURCES AND THE NUMBER OF CHANNELS THAT ARE PROVIDED BY THOSE AUDIO SOURCES.
