Information about Reference Recordings, "Prof" Keith O. Johnson and HDCD Recordings
www.referencerecordings.com, 27 July 2014 [cached]
Keith O. Johnson, our chief engineer and Technical Director, is a true audio legend, having designed and patented many innovative products in the professional and consumer fields. The RR Sound comes from his singular methods and equipment, hand-built or extensively modified by him. Microphone techniques range from single-point Blumlein to spaced omnis to complex studio mixes, depending on the musical forces and the performing space involved. Our goal is to recreate the sound of real musicians making music in real space.
"Prof. Keith Johnson has spent over 30 years developing a reputation for innovative thinking, technical achievement and musicianship which has elevated him to a position in the audio industry occupied by only a handful of visionaries. His intensive investigation of electronic behavior and acoustic perception have led most recently to his development (with digital engineer Michael Pflaumer) of the revolutionary High Definition Compatible Digital encoding process, produced and marketed by Pacific Microsonics (recently acquired by Microsoft). HDCD is widely considered to be the most accurate recording process ever invented.
For more than 30 years, Keith O. Johnson has served as Technical Director, Recording Engineer and partner in Reference Recordings. His 100-plus recordings for the label have long been considered the standard for high fidelity, and include three GRAMMY award-winners and eight additional GRAMMY nominations.

Keith O. Johnson: Recording and Audio Engineer Extraordinaire
...
Keith O. Johnson is a recording engineer whose more than 150 releases in classical and jazz include two Grammy winners and seven nominated for Best Engineered Classical Recording. Keith co-founded Gauss, Microsonics, and Reference Recordings, and holds any number of patents. He recently received a Silver Medal from the Audio Engineering Society at the 125th AES convention in San Francisco, California "for outstanding contributions sustained over 40 years, to the advancement of audio quality of recordings through innovation in the areas of analog and digital recording technology, transducers and music recording techniques. In addition he is a fellow and a Lifetime Member of the Audio Engineering Society.
KOJ studied computer science, biology, and music at UCLA, and did his graduate studies in electronics at Stanford University. For most of his life, for good and sufficient reason, his name has been prefaced by the honorific "Professor"; most of the high end community knows KOJ as Prof. Keith O. Johnson.
...
"It literally revolutionized the whole field overnight," according to Prof. Johnson.
Of particular interest to audiophiles and music lovers, while at Stanford University in the 1960s, Prof. Johnson created a solid-state 3-channel recorder that he used on more than 100 recordings. "It has 3.5-megahertz bias and still runs," he says. "I thought that if I could focus the magnetic field onto the tape, I could get rid of some losses that normally occurred in recording. And it worked."
Prof. Johnson went on to contribute his knowledge to the MCA DiscoVision video disc, engineered orchestral works for the Armed Forces Radio and conceived an optical CCD scanner, the Colortek system, which removes noise from damaged motion picture soundtracks. In the 1970s, he worked with rock band Ambrosia and partnered with producer Alan Parsons to develop the Projectron, one of the first tools to incorporate expressive polyphonic sampling.
In 1976, he joined producer Tam Henderson and Marcia Martin to form Reference Recordings, launching a legacy of high-end/half-speed mastered LPs and high-definition CDs (DDD). Prof. Johnson co-invented the HDCD technology with Pflash Pflaumer, and in 1996, they formed Pacific Microsonics to introduce the concept of high-resolution audio. In 2000, Microsoft purchased Pacific Microsonics and continues to incorporate HDCD technology into its PC offerings. Prof. Johnson subsequently consulted with Microsoft; one project, Speaker-Correction, uses modeled correction of speakers to improve computer sound and can be found in XP software.
In addition, as Director of Engineering for Spectral Audio Inc. for over 25 years, KOJ created the Vertical Dimension Topology, in which the electrical audio signal "drops down" into the amplifier circuitry along the Z axis to reduce to an absolute minimum noise-causing electromagnetic-field interaction. He also developed the Focused Power Geometry circuit architecture, a distributed array in which a separate power supply is physically located next to each output device of a Spectral power amplifier.
Most Notable Achievements
Renowned for his more than 50 pioneering years of recording and equipment design, Keith Johnson has always been at the forefront of high resolution audio. He has engineered nearly 150 classical and jazz albums including the aforementioned Grammys for Best Engineered Classical Recording.

Gregg, concerned that nothing was being done at Winston regarding the development of his video disc and mindful of the monolithic war being waged by 3M, left and formed Gauss Electrophysics with fellow employee Keith Johnson.
...
In a 1967 move to obtain a partnership agreement with Philips, Gregg and Johnson made a complete technical disclosure to Jan L. Omes in hopes of obtaining funding for development of a consumer video disc.
...
Philips declined, but despite their apparent disinterest to Gregg and Johnson, it would appear that it is from this point in time that Philips began development of an optical video disc system in their Eindhoven Laboratories.
...
Part of the collateral Gauss put up for MCA's investment was the patents Gregg and Johnson had already applied for to their audio tape replicators and video disc development.
...
Subsequent patents were filed by both David Paul Gregg and Keith Johnson, and it is these late 1960's filings upon which rests Gregg's claim as the "Father of Optical Storage."
...
Keith Johnson, then President of Gauss, was invited to tour the Torrance Laboratories, but his input and/or advice was never solicited concerning their endeavors.
...
In a 1991 interview with Gregg's partner, Keith Johnson, still a highly respected engineer in the audio/video field, he had this to say about Gregg's authorship: "Even though his (Gregg's) method might not be what we use today and probably might not have even worked, there is no question that he was on the right track and that he saw the critical key pieces that would fit and make the system work."
