AES Convention 136 · Paper 9045 · April 2014
Abstract
Following the recent trend of employing UHD video for increasing reality, audio object-based representation is one of the candidates for UHD audio format. The current paper is concerned with an effective method for the rendering of audio objects into a conventional 5.1 surround system. In order to represent the 3-D objects onto the upper hemisphere of the listener, the proposed system introduces object localization and virtualization of height speakers. The object is mapped to the 10.1 channel by using the object localization, and the 10.1 channel is rendered to 5.1 surround layout by virtualization based on the mixed structure by HRTF and VBAP. Subjective impressiveness was compared with the 19.1 loudspeaker system, which demonstrated almost same performance on localization in the horizontal and vertical plane. Therefore, the proposed system is capable of delivering sound moving effects to listeners over the conventional surround system.
