| Abstract(in English) | A design method of transaural filters is presented that can have sound images oriented to any direction beyond two loud speakers driven by binaural sound sources. Transaural filters are essentially inverse of a head related transfer function (HRTF) matrix, and are usually noncausal. To overcome this problem, it is shown that some paths can be ignored without much deterioration in crosstalk cancelation and 3D perception. Then the design of transaural filters is reduced to the approximation of a ratio of two transfer functions. Actual HRTFs have too much information which is sometimes too specific. So the ratio is simplified by emphasizing more important low frequency component. Then the magnitude and phase of the transaural filters are approximated by FIR filters. Subjective experiments show that our transural filters can achieve sound localization comparable to a binaural method using a head phone. |
