Scope of Research on High-quality Audio Signal Processing and Coding
Takehiro Moriya, Noboru Harada, Yutaka Kamamoto · NTT technical review · 2007
Current and future research activities of the Moriya Research Laboratory are introduced.To date, various compression coding technologies for speech and audio have been used for convenient and economical communication systems.However, compression makes the sound quality more band-limited and contaminated with unnatural distortion.We are seeking to construct more comfortable and more convenient communications systems by making full use of the broadband network environment.To achieve this goal, we are focusing on the development of lossless compression coding and exploring new concepts in quality through the use of newly developed devices and our deepening understanding of human perception.
