Abstract

The authors developed a 4-pi sampling reverberator, named VSVerb, which restores a 4-pi reverberant field by using information of dominant reflections which are captured in a target space. The timings and amplitudes of reflections are obtained from the analyses results of the sound intensities which are measured at the site in orthogonal three directions. The generated reverberation provides high S/N performance and enables to adjust various acoustic parameters with no additional measurements. These advantages provide the VSVerb with high affinity with post-production works. In order to enhance its affinity with object-based production schemes, this manuscript proposes a practical method to reduce a number of reflections from generated reverberations. The method, called Source Reduction, thins out reflections with less auditory deterioration.
