Abstract
A sound reproduction system for converting encoded stereo signals on input channels A and B into signals on left, supplemental left, right, and supplemental right output channels, respectively, that includes a left output channel for producing output signals intended to come from the left direction; a supplemental left output channel for producing output signals similar in level (intensity) to output signals of the left output channel and with reduced steered signal level for left direction signals; a right output channel for producing output signals intended to come from the right direction; and a supplemental right output channel for producing output signals similar in level (intensity) to output signals on the right output channel and with reduced steered signal level for right direction signals.
