Abstract:
A stereo sound generation apparatus and method of reproducing multi-channel sound input signals through two-channel speakers. The stereo sound generation apparatus includes: a preprocessing filter unit to reduce correlation between two-channel audio signals from among multi-channel audio signals and to generate a presence perception, a virtual speaker filter unit to convert the two-channel audio signals output from the preprocessing filter unit into a virtual sound source at a predetermined position, a signal correction filter unit to correct a signal characteristic between remaining multi-channel audio signals excluding the two-channel audio signals, and the two-channel audio signals output from the virtual speaker filter unit, and an addition unit to add signals to be output to a first channel from among the multi-channel audio signals output from the virtual speaker filter unit and the signal correction filter unit, and to add signals to be output to a second channel from among the multi-channel audio signals output from the virtual speaker filter unit and the signal correction filter unit.
