FIELD: physics.
SUBSTANCE: stereophonic characteristic expansion is achieved in sound reproducing systems with at least two loudspeakers. The input stereo signal, which includes several frequency components, is accessed. The loudspeakers are closed to each other. The frequency band of the frequency components is decorrelated, for example, during stereo signal preprocessing. The stereophonic characteristic of the sound reproducing system is expanded based on the decorrelation.
EFFECT: high efficiency of expanding a stereo system.
