Did We Exist?

Several years ago, just before I retired, I took a quick pass through McNally SmithCollege of Music, to document some of the acoustic treatments my tenure there created. That is documented here, somewhere, I’m pretty sure. Yesterday, I visited the remains of the school to look at the items that will be auctioned off this week. The evidence of my existence and participation in that facility are vanishing quickly.

Bullshit Arguments

A TapeOp Magazine opinion piece recently presented the dumbest anti-ABX argument I’ve heard to date; and I’ve heard a lot of really stupid arguments against ABX comparisons. Allen Farmelo's article title pretty much says it all, “The Problem with A-B'ing and Why Neil Young is Right about Sound Quality.” Because I’m a nice guy and it’s early in the morning, I’m not going to spend any time whacking away at the fact that there are so many old, deaf, mediocre rockers who imagine they possess golden ears. Neil Young, probably the single most prolific creator of awful sounding records in human history, is close to the last guy on the planet who should be promoting high resolution audio. Nuts, I went there anyway. So much for being a nice quy. 

However, the bullshit argument here is, “. . . we hear people talk about how one can't make out the difference between a hi-res MP3 and a 24bit WAV file (assumedly a difference similar to the one Neil Young feels is worth fighting for).  Admittedly a hi-res MP3 and a 24bit WAV are relatively close enough in resolution that many people will not be able to pick them out in an A-B test.

“But, we don't live with music like that.  If your'e [sic] anything like me, you listen to a lot of music in a lot of styles and - over the course of, say, a month - perhaps you've absorbed well over a hundred listening hours across many different albums on a few different playback systems.”

It gets better.

To “prove” his point, he uses what he imagines to be an analogy, “For example, when I started living with my partner I introduced her to what I call ‘good coffee.’  At first she kind of shrugged it off as my snobbery at work, and she couldn't really taste the difference.  But then, after months of drinking the good stuff, she found herself to be a bit of a coffee snob, too.  She could taste the difference because she had, simply, spent time with the good stuff.  The coffee revealed itself to her, slowly and subtly.  Her palate developed.  And the thing about good coffee is that it holds more detail, nuance and, therefore, interest.

“But it takes a while to become aware of that depth and complexity.  Had she done a flip-flip-flip A-B and made her choice to only drink the cheaper stuff because, ‘you know, they're basically the same,’ she'd have missed an opportunity to develop her palate.”

Farmelo is avoiding the simple test that would at least prove his coffee snob argument; now that she has developed “her palate” can she tell the difference when she does a “flip-flip-flip A-B?” If she can’t, you’re still full of shit. Likewise, way back in 2004 the Boston Audio Society performed a simple, repeatable ABX test of ancient 44.1kHz/16-bit technology and a 96kHz/24-bit source and, so far, no high-res audio equipment or recording professional or company has found a way to prove this test was incomplete or inaccurate. Humans love their delusions. One of the most inane arguments I’ve heard from an “audio professional” was the statement “I know what I know and I hear what I hear.” Totally incomplete. Doofus should have said, “I know what I think and I know what I think I hear.” It’s a useless statement, but accurate. 

There are a lot of reasons why I don’t take the fruitcakes and goofballs who call themselves “audio engineers” seriously, but this terror of reality and the limitations of their own hearing is high on the list. No, I don’t take sanitation engineers seriously either; they are just old fashioned, hard-working garbage men (or women).

Going Downhill

20180607_10001220180607_100039

Fortunately, I didn't have to listen to this nightmarish "sound system," but just looking at it was pretty depressing. This tiny faux-array JBL “full-range” speakers perched above and well behind apartment-sized subwoofers immedately made me want to ask, “When did Bose buy JBL?” From time alignment to diffraction and sound pressure field distortion problems, nothing about this mess would be able to reinforce anything resembling music. It isn’t even easy to move, unless the tiny speakers pack inside the subwoofer boxes. If there is any value system here, it must be “gain before feedback” because sound quality clearly is no consideration.

Wirebender Audio Rants

Over the dozen years I taught audio engineering at Musictech College and McNally Smith College of Music, I accumulated a lot of material that might be useful to all sorts of budding audio techs and musicians. This site will include comments and questions about professional audio standards, practices, and equipment. I will add occasional product reviews with as many objective and irrational opinions as possible.
