Waseda University, Sharp, and Pioneer Establish 1-bit Audio Consortium to Promote Next-Generation Audio Technology

On February 13, 2001, Waseda University, Sharp Corporation (head office: Osaka; President: Katsuhiko Machida), and Pioneer Corporation (head office: Tokyo; President: Kaneo Ito) established the 1-bit Audio Consortium with the aim of promoting next-generation audio technology.

Based on a proposal by Professor Yoshio Yamasaki, Global Information and Telecommunication Institute, Waseda University, research was carried out on high-speed 1-bit signal processing. This research led to the development of recording and playback technology that produces high quality and pure sound with limitless fidelity. This technology also serves as an ideal method for data transmission over networks. In addition, its high capacity to convert sound into signals helps save energy. Due to extremely low heat emission, smaller heat-release mechanisms can be used making more compact products possible. These elements make 1-bit audio the most promising technology to meet the needs of next-generation audio users.

Through its activities, this joint effort between industry and academia aims to increase recognition of 1-bit audio technology, contribute to advances in audio, and in the process benefit both music-related industries and consumers.
Located in the Pioneer headquarters, the consortium office will be jointly operated by Waseda University, Sharp, and Pioneer.
The supporting companies of the consortium will call for the participation of other companies wishing to manufacture and sell 1-bit audio products, and groups and individuals that wish to research, develop, and spread 1-bit technology. In addition, there are plans for regular research conferences where participants will announce the results of research and development efforts.
