AB  - The paper describes effective use of 4-pi (all directional) acoustical information of reverberation for post-production works. Measurement and analysis technique of sound intensities, VSV(Virtual Source Visualizer), is used for capturing 4-pi reverberations, and the obtained reverberations, VSVerb, are mapped on audio tracks of a DAW. In order to obtain precise rendering of spatial characteristics of the VSVerb, it is ideal to assign one object track to one reflection component. However, Dolby Atmos has the number of reflections restricted to 118. According to the hearing impressions by the authors show this restriction is impractical. This paper proposes a practical method to balance objects’ and beds’ tracks with less auditory deterioration.
