Abstract

Legacy 2-ch stereo music sources cause unnatural spatial impressions through earphones and headphones reproduction due to the lack of the crosstalk produced in loudspeakers reproduction. Perceptual widths of the stereo stage in amplitude-based and phase-based stereo width control methods for headphones reproduction were matched with that of the binaural rendering which simulates loudspeakers reproduction. Paired comparison between the stereo width control methods and binaural rendering was carried out to achieve the perceptual optimization for classic, jazz, and pop music sources. Concerning the amplitude-based stereo width control method, the suitable parameter value for each sound source could be determined from the results of the listening test. It is also found that the phase-based stereo width control method should be optimized in different parameter spaces.
