Cirrus Logic and Central Research Labs Team Up to Bring PC Users Immersive 3D Sound.FREMONT, Calif.--(BUSINESS WIRE)--Nov. 23, 1998-- Agreement Combines Cirrus Logic's Successful Crystal PC Audio Chips With CRL's Popular Sensaura 3D Audio Technology Cirrus Logic (company) Cirrus Logic - A manufacturer of integrated circuits including the Advanced RISC Machine and display interface processors and cards for use as Windows accelerators (requiring dedicated driver software). http://cirrus.com/. Inc. (Nasdaq:CRUS crus (krus) pl. cru´ra [L.] 1. leg (1). 2. a leglike part. crus ce´rebri ) today announced that it has licensed Central Research Labs' (CRL CRL - Carnegie Representation Language. Carnegie Group, Inc. Frame language derived from SRL. Written in Common LISP. Used in the product Knowledge Craft. ), Sensaura(R) 3D positional audio technology for use in its Crystal(R) PC audio products. The Sensaura technology will allow the Crystal audio products to provide exceptional 3D positional audio from just two speakers. "Today's hot new PC games are being designed to take advantage of the immersive and realistic sound reproduction that can be generated from two standard speakers or headphones Head-mounted speakers. Headphones have a strap that rests on top of the head, positioning a pair of speakers over both ears. For listening to music or monitoring live performances and audio tracks, both left and right channels are required. , using 3D positional sound See 3D positional sound. ," said Scott McDonald, VP and general manager of Cirrus Logic's Crystal Audio Products. "We chose CRL's 3D positional sound technology because of its extensive game developer support and superior audio quality. We plan to be shipping our PCI (1) (Payment Card Industry) See PCI DSS. (2) (Peripheral Component Interconnect) The most widely used I/O bus (peripheral bus). audio devices with this technology by next quarter." Originally developed for the music industry, and used by many recording artists including the late Frank Sinatra, Sensaura has been continually refined to provide very lifelike 3D audio effects. Such audio realism dramatically enhances the PC multimedia experience, whether for video and audio playback or for an exciting PC game. According to Mercury Research, Sensaura technology has been licensed by audio chip vendors who currently supply about 70% of the PC audio chip market. Games developer support includes over 130 games released or currently in development, including "Incoming" from Rage Software, "Jedi Knight" from Lucas Arts, "Unreal" from Epic MegaGames, "Need for Speed 3" from Electronic Arts and "Plane Crazy" from SegaSoft. Sensaura also supports the Microsoft DirectSound3D open standard. About CRL & Sensaura A pioneer in the audio industry, CRL can be credited with inventing stereo sound recording in the 1930s, starting with the foundational research and patent filing of CRL scientist Alan Blumlein on the fundamental principles of modern stereophonic Sound reproduction that uses two or more channels. Stereophonic is the formal term; "stereo" is more widely used. Contrast with monophonic. recording (patent GB 394,325; 1931). Formerly the Central Research Labs of EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. Music, and now part of Scipher plc, CRL's 60-year legacy of "world firsts" includes breakthrough work in commercial public broadcast television and the CAT body-scanner, which won the Nobel prize Nobel Prize, award given for outstanding achievement in physics, chemistry, physiology or medicine, peace, or literature. The awards were established by the will of Alfred Nobel, who left a fund to provide annual prizes in the five areas listed above. for its inventor. Continuing this stream of innovation, CRL has subsequently developed Sensaura Technology into the definitive standard for 3D audio throughout the 1990s, transforming stereo into a truly three-dimensional listening experience. Sensaura Technology has been patented by CRL, and forms part of the Sensaura portfolio of intellectual property, with 35 world-wide patent filings to date.
