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.

    I agree with you, Dr. Mark. HD audio is and will be great. But with all the snake-oil sales-pitches showing up, I cannot help but think that there is an equal part incentive to simply re-sell the old catalogue/files all over again.

  • Downloaded your sampler of hi-rez audio and thoroughly enjoyed the music. Sony’s latest smartphone was just announced (Xperia Z3) with hi-rez capabilities and a supposed 2 day battery life. Sounds interesting.

      I will have to check it out…thanks for the heads up.

    You do realize that CD only offer the highest bitrate of 44.1k/16-bit right? Getting 192k/24-bit out of a CD is not possible, and Pono is not claiming that it is.

      Correct…the Redbook specification for CD describes format as 44.1 kHz/16-bit PCM in stereo. Pono and Neil Young have proclaimed 192 kHz/24-bits as the necessary spec for “rediscover the soul of music”. If they are going to offer things at that level and are starting with CD resolution then they will have to offer standard CD quality, which means abandoning the 192 kHz/24-bit requirement or upconvert the CDs to the higher spec, which as you say is a challenge.

    I’ve gotta call you on this one.

    $499 for a 128 GB iPhone 6!??? Even though I’m not an Apple fan, if you’re selling at that price I’m in. My carrier, T Mobile, wants $849. A little steep for me.

    I have to admit I’m disappointed in you. For someone who constantly preaches about honesty in reporting cost/performance data, you’ve gotten sucked into the old “free phone” scam pretty easily. Obviously that $499 price is with a contract, the true cost hidden in monthly payments.

    I also looked at the Sprint site to check the cost of the HTC Harman Kardon – $680 – not chump change either.

    At this time I’ll have to take your word on M8 HK’s audio performance. The only reviews I could find were on “phone geek” sites and none of them even addressed the hi-res capabilities, other than to mention the pre-loaded files. Consensus seemed to be the sound quality was no better/worse than other top-of-the-line phones although there were comments, both pro and con, on the built-in audio processing options. What I’d want to see is a full audio-oriented review of the HTC, with comparisons to the established hi-res players out there and using a variety of headphones. All you’ve really said is that it successfully plays hi-res files and sounds good. I’m not saying it doesn’t perform, just that it deserves further study before it’s taken seriously as an audiophile music player.

    Then a side point… I’ve loaded some of your 69/24 FLAC sample files onto my $400 (full cost) LG Nexus 5 smartphone and they play fine. (In fact, my 4 year old Samsung Galaxy S plays them too.) Does that make it a hi-res player? Obviously not. I have no idea what happens between the reading of the raw bits and the headphone output. I do know it does not sound anywhere near as good as my desktop streamer/DAC/amp. With my 300 ohm headphones, while it can generate adequate volume, music sounds all wrong – I wouldn’t expect otherwise. But with good quality low impedance phones the Nexus sounds pretty darn good – excellent in fact when sitting in an airport or walking down a busy street. Of course, in those situations it would be highly unlikely that I could identify differences between 96/24 and 320 MP3.

    That said, I’m fully on board with your dream of having everything I need to listen to the highest quality music, in the highest fidelity, on any of my headphones , all right in my pocket at all times (and definitely not Pono.) I could get rid of my awkward desktop equipment. Play or stream anything. Anytime. Wherever I am. Wow! I just might pop $1000 for that. And get a nice phone to boot.

    Oh, and why is the guy in the Pono graphic at the 192 K level drowning. Everybody else seems to be doing fine. He’s waving for a life guard. Is 192 K bad? You’ve repeatedly said that 96 K is more than adequate for listening. Just bring your snorkel. Evidently only angels can hear the glories of 384. And dolphins prefer CD.

      That’s what it would cost if you walked into the Apple store, purchased the phone and a service agreement. Right. I understand the contract is part of the incentive get you purchase the new phone…but that is still the cost of getting the new phone if you do.

      I’m hoping to get some hard specs on the HTC M8 HKE Phone…stay tuned.

      Any phone that can natively play a 96 kHz/24-bit soundfile qualifies as a High-resolution playback device. Then you have to figure out whether the components (DAC chip, headphone amp and headphones) are worthy. I played a lot of my files on the phone into a set of PM-1 Oppo phones and into a set of JBL M2 Studio Reference monitors and it sounded amazing.

    I believe Apple is going to enter the HD audio with the iPods and Beats tied togheter as a way to keep the device up to date and to make the consumer willing to buy it , since at this point with all the smartphones doing basically the same that an iPod does and much more , it is not probable you are going to spend your money on an iPod unless it has new features as HD playback capablities.

    More of a question . I own 2 Ayre QB9 DACs. They are superior to cheaper DACs, I have owned. I believe Charles Hanson is the force behind Ayre. An Ayre claim to fame is a proprietary processor & other features. Does the Pono player offer this? I agree the source material is very important, but how important is processing? A Meridian CD player can sound impressive.

      I can’t really say what the inner workings of the Pono player will be. I was frankly very surprised to hear that they were planning 2.0 version. I had thought that the KS initiative was just a catalyst to get them the money to launch the download service. I know that the unit I heard in Chicago was built by Meridian and sounded really great. I’m very confident that Charles can play in that league. But we’re still talking about a portable device with limited power etc. It will have to be dramatically better than the other portable devices to get any traction. They’ve pre-sold 15,000 or the 1.0 version…I don’t see them being a hardware company.
