Dr. AIX

Mark Waldrep, aka Dr. AIX, has been producing and engineering music for over 40 years. He learned electronics as a teenager from his HAM radio father while learning to play the guitar. Mark received the first doctorate in music composition from UCLA in 1986 for a "binaural" electronic music composition. Other advanced degrees include an MS in computer science, an MFA/MA in music, BM in music and a BA in art. As an engineer and producer, Mark has worked on projects for the Rolling Stones, 311, Tool, KISS, Blink 182, Blues Traveler, Britney Spears, the San Francisco Symphony, The Dover Quartet, Willie Nelson, Paul Williams, The Allman Brothers, Bad Company and many more. Dr. Waldrep has been an innovator when it comes to multimedia and music. He created the first enhanced CDs in the 90s, the first DVD-Videos released in the U.S., the first web-connected DVD, the first DVD-Audio title, the first music Blu-ray disc and the first 3D Music Album. Additionally, he launched the first High Definition Music Download site in 2007 called iTrax.com. A frequency speaker at audio events, author of numerous articles, Dr. Waldrep is currently writing a book on the production and reproduction of high-end music called, "High-End Audio: A Practical Guide to Production and Playback". The book should be completed in the fall of 2013.

    Hi Mark, You’re being generous. The hi-res “definition” you speak of is not just inaccurate, it’s deceptive, particularly in the use of the word “quality” in any of the four categories presented with that definition.

    Consumers need a more disciplined description that addresses quantifiable standards rather than the industry’s marketing needs. Given the strangely defensive attitude of some of the drafters of that flawed document, I doubt we’ll have a forthright document soon.

    Another suggestion instead of fighting the CEA and major labels: go around them with a major standards body, specifically the ITU, to develop a robust definition for high resolution/high quality recordings.

    The ITU may not seem like the right body, but I think they are, or at least the best fit I can find. Look at the nature of the standards they’ve developed, for example http://www.itu.int/pub/R-REP-BS/en and http://www.itu.int/rec/R-REC-BS/en. They’ve addressed many difficult topics that are relevant for areas that go far beyond just broadcasting.

    It strikes me that the issue of a robust definition of the quality of the recording being broadcast (prior to any broadcast-specific processing) would be something of interest to the ITU, and definable in a way that does exactly what you want it to do, Mark, for defining the quality of recordings as distributed for playback prior to consumer playback processing.

    Of course, you may have already been thinking of this option and it didn’t work out, but if not, it seems worth a meeting with or a call to the right ITU person to explore it. To the extent that the ITU is opportunistic in looking for ways to add value within their broad scope, pointing out the complete market failure of the industry to robustly define HRA itself can be leveraged to help make the case for their involvement.

    I don’t know anyone at the ITU, so I can only make work for others on this 🙂 But seriously, I spent many years in my early career trying to knock down barriers, and it took me a while to figure out that going around them is frequently far more effective…

      This might serve as an alternative means of getting some rigor in the definition. My bets are on the JAS and the logo right now…we’ll see.
