Sound Image Rendering System For Headphones

Manabu Okamoto; Ikuichiro Kinoshita; Shigeaki Aoki; Hiroyuki Matsui

We have developed a sound image rendering system for headphones that enables anyone to easily create realistic 3-D sound. This paper presents the structure of this system, and the results of subjective tests confirm the systems feasibility in affecting sound. This system has been used in the making of music CDs.
