Current CDs are limited by technology that is 20 years old. At the moment there are several high bit rate delivery systems being proposed. These include the Digital Audio Disc (DAD), Digital Versatile Disc (DVD), and Direct Stream Digital’s Super Audio Compact Disc (SACD). RPG® is privledged to have been selected by the industry’s high resolution, surround sound visionaries to provide acoustical solutions for these new formats. DTS has selected RPG® products for their critical listening environments, as well as their trade show exhibits, to demonstrate the sonic benefits of their technology. Tom Jung is using RPG® technology at DMP to critically evaluate his pioneering DTS and DSD recordings. Jack Renner and Michael Bishop of Telarc have used RPG® technology for the past 12 years to create their award winning recordings. Bob Ludwig at Gateway Mastering Studios is using RPG® in his critically acclaimed 96 kHz/24 bit mastering room. Gateway has also chosen our Skyline® and BAD™ panels in their new DVD home theater studio. We collaborated with Professor Chris Kyriakakis and Tom Holman in the application of RPG® products in the Multichannel Music Immersive Audio Laboratory within the USC Integrated Media Systems Center. Sean Olive and Floyd Toole are using Skylines® and the Room Optimizer™ in Harman International’s Multichannel Listening Laboratory to evaluate the psychoacoustical effects of listener and loudspeaker placement. A New Laboratory for Evaluating Multichannel Audio Components and Systems, a paper describing this facility, will be presented at AES in San Francisco this September. Sony and RPG® have enjoyed a long collaboration and I wanted to personally thank them for their confidence in our technology. Our collaboration began in 1986 with David Smith at Sony Classical before the move to Sony Music’s 54th Street facility. At Sony Classical, the temporary edit suite was outfitted with an RPG® Diffusor System of Abffusors®, Diffusors® and Bass Traps. The relationship continued at Sony Music, where most of the recording, mastering, and production rooms incorporate RPG® products. Sony’s legendary mastering room has produced several hit recordings like Titanic, Lion King, Michael Bolton, and Mariah Carey. Thanks to Al Smith of Sony Music for this level of committment. The most recent RPG® Diffusor System at Sony Music is in Studio C, designed by Harris Grant Associates. RPG® would also like to thank David Kawakami, Director of Corporate Business Development for Sony Electronics Hi-Fi Division, and Tom Jung of DMP for selecting RPG® to acoustically design and treat the Sony demonstration room at Hi-Fi 98 in Los Angeles. We used our new VariScreen™, which is a self supporting hinged panel with an absorptive side and a BAD™ diffusive side. The VariScreens™ quickly converted the hotel room into a credible presentation venue for Sony’s new Super Audio Compact Disc (SACD). The SACD format has been created by Sony Corporation and Philips Electronics to provide unprecendented two channel and multichannel sound. It employs Direct Stream Digital, a one bit recording technology that samples the musical signal at the phenomenal rate of more than 2.82 MHz per second (64 x 44.1 kHz). As a result, an extremely smooth digital waveform with an unparalleled frequency response of DC - 100,000 Hz is achieved, with a dynamic range of more than 120 dB. Presentations about their experiences with this new and exciting technology were made by Telarc president Robert Woods and engineer Michael Bishop, Tom Jung, President of DMP, and Lori Beaudoin, President and General Manager of Mobile Fidelity. RPG® is committed to developing the acoustical standards for the next generation of multichannel music and home theater surround sound formats, as it did for stereo in the early 1980s. We are also forming strategic alliances with the industry’s leading home theater designers and system integrators. This collaboration allows RPG® to bring our wide range of affordable, leading edge, acoustical technology into residental spaces. Dr. Peter D’Antonio |
