A Study on Implementing Switching Transfer Functions Focusing on Wave Discontinuity

Document Thumbnail

Many papers have described moving sound image localization schemes that use loudspeakers or headphones. Most of these schemes are based on switching spatial transfer functions, so wave discontinuity occurs at the moment of switching, which degrades the sound quality. While the characteristics of the wave discontinuity depend on the moving sound image localization schemes, no paper appears to have considered the relationship between the wave discontinuity and the scheme used. To rectify this omission, this paper examines three approaches: simple switching approach, overlap-add approach, and fade-in--fade-out approach. We assess the sound degradation caused by wave discontinuity, and use the objective measure of spectrum distortion width to quantify the wave discontinuity. We also carry out paired comparison tests as subjective assessments. Both assessments verify that the third approach is the best of the three.
