Stereo-Width Control Based on Creation of Virtual Sound Field


Takahiro Umayahara, Haruhide Hokari, and Shoji Shimada
Nagaoka University of Technology, Nagaoka, Niigata, Japan

A new stereo-width control system is proposed. The authors’ approach was to create a virtual sound field in the recording side, not phantom sources in the reproduc-tion side. The main process of the proposed system is signal-dependent spectral modification under the frame-work of analysis/modification/synthesis. Listening tests indicated it offers good performance.
