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, it seems to me that the final conclusion can only sensibly be reached by an audition comparison of the ‘ultra’ CD and the standard issue item, with you as the listener.
    But just as the various agents of misperception are to be factored in to typical, uncontrolled comparisons, so is your staunch belief that based on the numbers, the discs must sound the same. I don’t care for voodoo-based claims either, and at this point I can state to be 100% free of placebo effect or any of the other cliches that are used to reduce the significance of what we hear as opposed to measure. In turn, I would hope that you could make a level-matched comparison and let your very experienced ears do the judging. If one does indeed sound better than the other…As an audio company principal and sage said to me recently,”When someone claims to have all the answers yet the ear reports differently, perhaps we are asking the wrong questions.” Thanks.

      Craig, auditioning the sound of these “hyped Ultra HD CDs” is not necessary. I would hope that we can agree that a Redbook CD has a rigorous set of specifications…we all know them as 44.1 16-but linear PCM stereo. FIM and Winston Ma and his minions (including clever copywriters) can say anything they want about what they do prior to locking down a CD but they can’t do anything to advance the fidelity of a CD over what its spec says it can do. Right? The argument to let you ears do the judging can only happen after it is established that one is actually comparing two things that are different. I won’t waste my time or money buying a “PureFlexion” $40 CD and compare it to another CD containing the same data. No one else should either.

        I’m sure you could get your hands on a so-called premium quality CD w/o paying for it. If the two do indeed sound identical, then the comparison will need to last no longer than 10 minutes max. I bet you have 10 minutes.

        OTH, if they sound noticeably different, not even getting to ‘better’ or ‘worse’, that too will be quickly audible.But if one does sound noticeably better, you won’t want to stop listening. Every time I audition something that causes me to listen to my oft-played demo/evaluation tracks as if I’ve never heard them, it is because something truly superior has just been inserted into my system. I know how to be clinical too, but when I listen for pleasure, about 70% of the clinical perspective is tossed aside; the other 30% never turns off from many years in this business. mark, we are opening a new stereo store in Santa Rosa; would you like to be the center of a Hi-Res event this Fall? Best, Craig

    Comparing the FIM HD with conventional CD, will reading error rates be lower on the FIM’s disk?
    Assuming a disk is exactly === original master (digital recording), the sound quality will depend on what happens after the data are retrieved. The question is then about the most efficient way to reproduce the original master in bit perfect manner. If that’s case, nothing bit direct download. Right. Forget all the intermediary medium.

    Just my thought.

      Absolutely…so why do these BS products exist? And more importantly, how can a company like FIM stay in business?

      Sorry it was so long. I was amazed at the amount of crap being spewed on that page.

    Gee, I happened to look up the prices of these discs. $39.99. No wonder the claims made about the manufacturing process. You have to, somehow, justify the cost. Vinyl pricing! I’ll pass!

    Why are none of these scam artists being prosecuted for false advertising? Only in audio can people get away with such BS.
