Abstract
Multiple audio streams are spatially separated with a context switching system to allow a listener to mentally focus on individual point sources of auditory information in the presence of other sound sources. The switching system simultaneously directs incoming sound sources to different spatial processors. Each spatial processor moves the received sound sources to different audibly perceived point sources. The outputs from the spatial processors are mixed into a stereo signal with left and right outputs and then output to the listener. Important sound sources are moved to a foreground point source for increased intelligibility while less important source sources are moved to a background point source.
