AB  - The aim of this study is to investigate the perceived width in binaural synthesis. To synthesize sounds with extended source widths, monophonic signals were divided by 1/3-octave filter bank, each component was then distributed to different directions by convolution with head-related transfer function within the intended width. A subjective listening experiment was conducted by using pairwise comparison to evaluate differences of perceived widths between stimuli with different synthesis widths and distribution methods. The results showed that this processing method can achieve a wider sound source width in binaural synthesis. However, effectiveness may vary with spectrum characteristics of source signals. Thus, a further revision of this method is needed to improve the stability and the performance.
