抄録

The authors develop a 4-pi sampling reverberator, named “VSVerb,” which restores a 4-pi reverberant field by using information of virtual sound sources which are captured in a target space. Acoustical properties of virtual sound sources are detected from measured sound intensities, and they are translated into time responses. So far VSVerb has given either plus or minus signs to reflection sounds randomly in order to reduce DC bias of a reverberation. In this report, the authors propose an alternative method which detects phase characteristics of reflection sounds, i.e. detected sound sources, by analyzing obtained source-intensities and their related wave forms. By using the method, VSVerb becomes to generate 4-pi reverberations by 100% of analytical procedures.
