Dr. AIX's POSTS HD-AUDIO NEWS — 17 May 2020


It’s been a very challenging semester. The shutdown of face-to-face classroom instruction caused no end of headaches, compromises in the quality of teaching, and some serious doubts about tests and grading. I just finished grading 55 final exams in one class (yes, I teach a Digital Production Strategies Course with all 55 majors in it!) and 18 in my advanced recording class. I probably need to research methods of handling secure test taking because there were more than few instances of people copying directly from the web during the test! I was hopeful that all of my students would be honest and respond to the test as if they were in my classroom. Some couldn’t help but look up answers online.

When the font suddenly changes in a submitted paper, it might be because that paragraph was copied from an online article. There is no doubt about the plagiarism when the quoted section references additional information and links, “Timecode is a track that allows for synchronization and editing within a video or an audio file. SMPTE timecode is a standard that was created by the Society of Motion Picture and Television Engineers (SMPTE). While there are wide variations in possible uses, I’m going to restrict this article to the topic of how we, as programmers, can use SMPTE timecode to synch up our lighting cues with music. I’ll have links at the end if you’d like to learn more about the protocol. This was actually submitted on a paper.

The university’s policy on cheating is to issue an immediate “F” and additional possible disciplinary action. I was very disappointed. And it appears that the fall semester will be more of the same. Hard times are ahead.

The iTrax-Sprint Ultra HD-Audio Sampler

I watched Steve Guttenberg on his YouTube Channel the other day talking about a free sampler available from Todd Garfinkle’s MA Recording label. Todd and I were students together at CSU Northridge many years ago and competed to supply recording services to students wanting their senior recitals recorded. Like me, he operates a small audiophile label and usually attends the same trade shows as I do. We’ve even shared rental cars and a booth on occasion. His recordings are very highly. regarded. Steve explains that Todd records with only two microphones in reverberant spaces all over the world. A sort of “capture the music and location” approach.

AIX Records does the same thing…almost. Most of my albums were recorded in Zipper Auditorium at the Colburn School of Performing Arts in downtown Los Angeles. It’s a terrific hall with great reverb and a world class 9-foot Steinway piano.

I was inspired by Steve’s video and Todd’s generosity to make available the iTrax-Sprint Ultra HD-Audio Sampler to readers of this blog and followers of AIX Records on Facebook. As many of you know, I have been slowly bringing iTrax back. It’s a lot of work but there are about 20 albums from the AIX Records catalog on the site (all are available is you simply write to me).

If you’re interested in hearing 18 of my favorite tracks from world class musicians including: Willie Nelson, Albert Lee, Carl Verheyen, Laurence Juber, and The Dover String Quartet, please visit the site and download the tracks in either FLAC or WAV. And these are real HD-Audio tracks!

And don’t be shy about submitting your results. There are no right or wrong answers….it’s a survey to see whether high-resolution audio is audible. If you’re done listening, you can submit your results here (submissions page).

Some more crazy talk…

I spend too much time reading equipment reviews, sales marketing materials, FB posts, and online comments. And I use my knowledge as an audio engineer, professor, author, and audiophile to sort the wheat from the chaff. And it’s hard! If you’re a newbie or easily influenced music lover, the marketing messaging and even “reviews” by professional journalists can be overwhelming. Without much commenting, here are some of this week’s favorites:

A piece titled, “The Secret Life Of Super Audio Compact Discs (SACDs)” included these exaggerations or outright misinformation:

“Super Audio Compact Discs (SACDs) offer improved sound quality over their non-super counterparts.”

And there was this comment from an ardent fan or the failed technology:

“SACD was and remains the best sounding format, not because it has less resolution than Pure Audio Blu-ray or DVD-A:s, but probably because the DSD technology is superior to PCM for music.”

None of the specifications of DSD are superior to PCM for music or any other type of recording. The marketing and spinmeisters at the publications worked. FYI Mainstream professional audio engineers avoided DSD like the plague.

Over at The Absolute Sound, the usual craziness regarding cable reviews was on view. This time reviewing a “budget line of cables and interconnects” from Synergistic Research, a brand well-known to audiophiles (and one I avoid no matter what the price range). The author actually described his current ultra expensive cables this way:

“Though my current set of Crystal Cable Ultimate Dream wires from Gabi and Edwin Rijnveld of Crystal Cable and Siltech is undoubtedly the best (the most vividly and accurately colored, powerful, quick, detailed, three-dimensional, just plain lifelike) stuff I’ve had in my system in better than forty-five years of cable-swapping, its incredibly lofty price tag brings into painful focus a problem I’ve had with “gourmet” cables from the get-go.”

Prices: Interconnects, $20,900 per meter pair; speaker cables, $47,000 per 2.5-meter pair; power cords, $12,100 per meter length. Anyone that would fork over that kind of money for cables of any type has lost their mind in my humble opinion. Note that no one in the professional world uses or endorses cables like that. If the recordings that we cherish are made in studios using Mogami, Belden, and Canare cable then perhaps we should adopt those brands and avoid brands that rip us off. It would also be nice if the reviewers that write this nonsense would learn a little about the art and science of audio. When you read a review that spews this nonsense, just stop.

And then there’s the expected back and forth between SR supporters and those who know better in the comments. It usually doesn’t end well.

Here’s a comment from the author after a particularly rude back and forth by “adults”:

“Over the years, the exorbitant cost of high-end cable has so troubled me that I used to regularly swap out whatever goodie I was currently listening to for old-fashioned zip cords of various twists and gauges, just to make sure that I was hearing what I thought I was hearing—and not falling for a price tag. Of course, the losses of bandwidth, resolution, transient speed and definition, density of tone color, and lifelike dimensionality, solidity, and presence were always and inevitably the same. Which is why, after a decade or so, I stopped AB’ing and just accepted the fact that (to a greater or lesser degree) when it comes to wire you get what you like and what you pay for.”

This guy gets paid by the publication — and undoubtedly get free products from the company he’s reviewing — to spew this nonsense. Saying things like “the losses of bandwidth, resolution, transient speed and definition, density of tone color, and lifelike dimensionality, solidity, and presence” sound like legitimate quantifiers for sound but in over 45 years of making records, I’ve never hear any producer or engineer use those terms — EVER! And don’t forget that the normal zip cord and wire of typical quality lurks just inside the components he’s hooking up.

This is what happens after the $12,000 power cord gets plugged in!

And finally…

I asked an advocate for analog reel-to-reel recording what quality his preferred format possesses that high-resolution digital doesn’t? He responded by claiming that analog recordings have much more “density” than digital recordings. Once again, another new term to describe something that acousticians and physicists have already described more than adequately. Personal preferences aside, PCM digital recordings capture everything that was in the original acoustic performance.

The discount continues…
