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.

    So much of what we kick around has semantic issues built in. When folks go from MP-3 to vinyl, it is very clear to me that they are relieved to get away from the noxious, welded-in distortions of lo-fi digital, and to be presented with a much more innocuous, easier to live with family of distortions.

    I do find the CLASP system to be kind of hilarious. It is also true however that many of the best-sounding CD’s are analog recordings digitally transferred and mastered, so there is evidently an issue of complementary sonic qualities that these engineers are seeking. I’d call it the pursuit of inoffensive,analog distortions while preserving the SN and archival qualities of digital. Pretty soon they’ll be adding the sound of crackling LP’s too.

  • I particularly enjoyed the little work Knopler did with Chet Atkins. I always felt early on that Chet’s sound was ahead of most. Nashville recordings by and large seemed to benefit from a well treated clean sounding studio. Was Chet doing something special or just being careful, who knows ?

    As for the Hi Rez, we have VanHalen out today with yet another example of “remastering” offers. With aging artists, unwittingly or unwillingly going this route for the take, can there be any short term hope for ANY better format ? It’s been 35 plus years of “CD”, will it be another 20 or more of “CD” rei-invention. Can’t one make the case that DSD folks see their flawed case as something dear to the “storage” gods ? Let’s all just listen and do the “hokey-pokey”.

  • “Having dedicated myself to producing and releasing the cleanest, most accurate sounding, pure music recordings, I’m surprised that prominent engineers and producers believe that “everything old is new again”. ”

    Very glad to hear you taking that position Mark. Since the very earliest days of audio recording the goal for future progress has been to get ever closer to reproduction of the live event, to be able to have equipment that could reproduce exactly what the microphones heard in the studio or concert hall. Seems like in recent years everyone in the recording chain has been looking to add some type of distortion to the recording that pleases someone, but takes us ever farther from the intended goal.
    We have such wonderful tools at our disposal today that have the possibility of delivering a playback that might set us on our behinds. Lets get back to the ideals of the direct to disc recordings of the 80 and 90s. Position the mics in front of the performers in as best a positions as possible, get rid of as much of everything in the middle as possible, and feed the least manipulated signal as possible into your digital recorder. Throw as much of your console and ProTools aside as you can. They can distort the pure mic signal but never improve it.
    The best recordings I’ve ever heard were done by engineers who took the purist approach even though they were using electronics of very dated design. A David Manley purist approach using today’s HDA tools could set the industry back to pursuing the true path to High Fidelity. Take a few moments to read the sonic path of David Manleys minimalist recording approach.

    If we are going back to the “original: sound we need to get rid of the vocal doubling (or tripling) on that Knopfler recording. VERY distracting, IMHO. Just ’cause you have lots of tracks available doesn’t mean you have to use them all.

    • This has been a common production technique for a very long time…the Beatles did it in the early 60s and Mary Ford did it with Les Paul in the 50s.

    >> In my perfect world, any of these “sound enhancement processes” can be applied at the delivery end of the music reproduction chain.

    Delivery end?? As in under my control or choosing or at the final production stage??? I so wish there were more consumer side options so I could hear many different attributes of the recording, much more that the two channel static stylized sonically diluted presentation that the investor, profiteers, and spin master spew in our direction.

    I wish I had the option, as a consumer, for many choices of surround mixes to focus on what I want hear or, better yet, explore to find something I didn’t catch before. There are so many interesting sounds that go into a production that we can barely heard in a 2 channel, average fidelity presentation. What a shame! Some performing artists or mixing genius added some subtle and wonderful nuance that almost no one can detect or appreciate.

    I guess I want Mark’s multiple sound stage presentation on steroids!

    I’ve been told I missed my calling and should have been a recording engineer I guess that’s what I need to do as a 61 year old person (shure.. Humm, always misspell that 4 letter word for some reason ) to get what I desperately want to hear because it’s not coming through the consumer pipeline for a few more decades.

    Mark, in the world of virtual media, do you ever think of making more options available than the alternate sound stages? Can you create a new market for such a thing?????

    • I would love to give you control,but I was actually thinking that the parameters setup by the mastering house could be used as metadata to affect the audio in realtime during playback.

  • My heard goes out to the recording engineer. I’ve seen Knopfler in person a number of times and as can be heard on the video here he has a very soft voice and sings at a very low level. Always seemed like the live mixer was struggling to get Mark at a level he could be heard and many times I still could not make out the vocals. Imagine it’s a bit easier in the studio.
