| Outline of Final Research Achievements |
The sound field reproduction can be divided into two categories. The first is physically assured and engineeringly realized method, that reproduces physical characteristics such as wavefront. The second is based on artistic manipulation and examples are the music package media for two-channel stereo or multi-channel surround system. Although both methods aimed to reproduce "good" sound field, these methods have been considered being essentially different.
The purpose of the current research is an integration of both methods. The system that can be used for both methods had been constructed and detailed examination had been conducted.
As a results, each method had desired frequency range for precise reproduction; the low frequency for engineering method and high frequency for artistic method. The hybrid method that divide frequency, process individually, and re-integrate, was therefore proposed. The availability was verified by objective and subjective examinations.
