Abstract
In a stereophonic sound reproduction system in which stereophonic left and right signals are treated to have a level difference therebetween for establishing a localized sound image spaced from the midpoint between left and right loudspeakers, the level difference between such left and right signals is reduced as the frequency thereof increases for improving the localization of the sound image resulting from the application of the resulting or converted left and right signals to the left and right loudspeakers.
