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.

  • Certainly sounds like one of those industry hand-stampings that was never intended to be clear or hold any standard. Rather it was suppose to imply one thing, and allow almost anything so profit can be made. It is rather disgusting, and should be embarrassing to those involved. It won’t be. As long as the greenbacks flow, it’s all good.

  • Too many lawyers were involved in this

    Your investigative work simply angers me! There I was, happy to be paying extra bucks due to JAS’s vaulted HRA logo, telling my friends that they were listening to the “actual” highest fidelity version they will ever hear, (a bucket list sort of experience), and now, I may be simply a victim of another snake oil sales campaign!

    What it boils down to, we still do not have any method to actually trust what we are listening to is the highest quality version available except from your, (now needed even more), planned listing service and then we have a chance to confirm one has the best, (else scope every song one plays)!

    Thanks for all the work on this issue. Muchas Gracias

    Hi Mark,

    I believe the letter you received, and the frustration of those who read your daily posts – who just found out how much the JAS logo is really worth -, prove the point I made two posts back, on Tuesday: What we need is an App that can make spectagrams out of any track available in our computer, Tablet, or Smartphone!

    We could all write letters to the people behind the JAS logo and criteria, and we’d get the same response, but QOBUZ customers with evidence in their hand, can exercise real pressure on businesses like QOBUZ, HD tracks, etc.

    One could buy a more expensive piece of software like Adobe Audition, that requires some minimal technical expertise, and spend unnecessary time and money that could be avoided with an App that assesses the quality of HRA downloads. That would be a real option to put pressure and a stop businesses like QOBUZ from trying to fool us.

    An App like this would constitute an interesting project for someone interested in audio and music, and it would provide customers with a real tool to exercise their rights as consumers, plus, like any App, it would go viral and become massive.


    • Thanks…I’m very fortunate to have polite and interested readers and commenters here at REAL HD-Audio.com. I have read the many of the rants of flaming comments on other forums and am dismayed that moderators allow it to continue. After all, we’re talking about audio here. I read the comments and am amazed at the lack of knowledge that people skew…but that’s part of our passion.

      Ken is a brilliant authority of digital audio. His idea to price high-res audio the same as standard resolution audio is interesting. But it won’t happen. Not when the existing sites are getting people to pay premium prices for the same old thing.

  • What I have learned: never pay more, than you have to pay for a 16/44.1 version.
    Except – of course – if you by some of Mark’s files/discs 😉


    • Thanks…I appreciate the exception. If I were making big bucks or even any bucks on this venture, things might be different.
