A high-frequency band equalization method is proposed to further reduce the timbre coloration in transaural reproduction with two frontal loudspeakers. The high-frequency responses of a pair of filters for transaural synthesis are equalized by a frequency-dependent factor so that the overall power spectra of the responses remains constant, and the low-frequency responses of transaural filers are kept intact. Psychoacoustic experiment validates that the proposed method reduces the timbre coloration in transaural reproduction without introducing obvious perceivable directional distortion for virtual source in the frontal quadrants of the horizontal plane.
