Classic double r record

RR(Reference Recordings) company, founded in p>1976, is a famous American fever brand. The recording technology developed by Keith Johnson, a sound engineer, has made this brand famous for its top-notch effects. In 1993 and 1997, it won the Grammy Award for Best Recording Engineering Technology twice. The most dazzling feature of RR in the digital age is the development of HDCD (high defense CD), namely "compatible high-resolution digital technology". HDCD technology is to sample analog signals with a sampling frequency of ——88.1kHz, which is twice higher than that of conventional CD, in order to maximize the high-frequency response and reduce the defective distortion. Such a high sampling rate also leaves enough space for HDCD encoding operation. The 24-bit quantization sampling is 256 times higher than that of the 16-bit system, and the dynamic range is increased to 12dB. This high-precision, wide-band digital signal forms the basis of HDCD coding and manufacturing, and its data information is huge, which is unmatched by the conventional CD pulse code modulation format.

even if p>HDCD is played on an ordinary CD player, its sound quality is better than that of ordinary CD. When playing HDCD encoded records on CD player with HDCD decoder, the sound quality is even more beautiful. Through HDCD technology, sound engineers can capture more details in music performances and faithfully preserve the genius performances of great musicians.

RR Company has released dozens of HDCD CDs so far, including audiotapes "Invincible Disks" and "azazel" which are most familiar to enthusiasts. And this RR's "Selected 3th Anniversary of Typical Recording" is the latest collection of demonstration and test recordings, with 13 pieces of music (including excerpts) from 13 RR HDCD discs. Its content far exceeds all previous "highlights". Moreover, because the music on the disc covers the types and styles of different works, this disc has more choices for appreciation and testing.
