Abstract

Widening stereophonic response is achieved in sound reproduction systems with at least two loudspeakers. A stereo signal input is accessed, which includes multiple frequency components. The loudspeakers are close to each other. A frequency range of the frequency components is decorrelated, e.g., upon pre-processing the stereo signal. The sound reproduction system's stereophonic response is widened, based on the decorrelation.
