ABSTRACT
Since the CD, developed in the early 1980s, has almost reached its upper limitations of sound quality, Sony and Philips joined once again to develop a new system with an extremely high sound quality, surpassing the limit of CD. To review proposals, the three major trade associations of the recording industry formed the International Steering Committee (ISC). These three associations are the Recording Industry Association of America (RIAA), the Recording Industry Association of Japan (RIAJ) and Europe’s International Federation of Phonographic Industry (IFPI).
