Virtual Source Width in Binaural Synthesis with Frequency-Dependent Directions

To control the perceived source width rendering by headphone, a method to distribute different frequency bands of a sound source to different directions by binaural synthesis was investigated. Three types of signals including two anechoic musical recordings and white noise were filtered and split into 1/3 octave bands, and each band was convolved with HRTFs from different directions within the intended source width range. Subjective listening tests were conducted to evaluate the performance of this process. There are no evident results showing that this method can successfully synthesis extended sound images. However, it suggests that the distribution of bands according to spectral characteristics of signals is necessary to synthesize sound image without displacement of localization.
