Sound Scene Control of Multi-Channel Audio Signals for Realistic Audio Service in Wired/Wireless Network

Abstract

In this paper, we proposed the sound scene control (SSC) of the multi-channel audio signals in MPEG Surround to enhance the MPEG Surround with respect to the functionality. To add a new functionality to the MPEG Surround, we proposed the multi-channel sound scene control by modification of the spatial parameters such as the channel level difference and the inter-channel correlation. Even though the panning law is directly applied to the spatial parameters, the output channel signals are successfully panned by given panning angle. The quality and the localization ability of the proposed SSC are confirmed by the subjective listening test.
