<P>PROBLEM TO BE SOLVED: To carry out exact interpolation using transfer function data in a frequency region. <P>SOLUTION: The transfer function interpolation method is equipped with a phase lag eliminating step of eliminating phase lags commonly contained in the dispersion frequencies of a spatial transfer function from a sound source to a sound receiving point, a transfer function calculating step of calculating a spatial transfer function in an optional frequency from the signals processed at the phase lag eliminating step, and a phase lag adding step of adding a phase lag to the signals calculated by a transfer function interpolation step. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
