...most of the pros I have talked to or dealt with rarely go above 44.1 for audio or 48 for video, which are the target mastering rates. I can't give you exact numbers, but I'd take an edumacated guess that it's probably somewhere around 7 in 10, and certainly more than 50%.
So, the question is; where is the perception that so many pros recommend or use higher rates coming from?
..................
I can't prove this, I don't have numbers, but my gut impression is that there is enough of a spread amongst converter performance categories to wash out any perceived trend towards better sounding converters at higher rates
based upon actual converter performance, especially when you consider the balance of converter quality in the overall market tends towards the cheapo crap stuff (there's far more mudAudio Fastraks out there than there are Apogees with Antelope clocking

.)
I don't move around from studio to studio enough to talk directly to lots of different pro engineers...and I haven't spent lots of time considering this issue over the last 10 years. Heck, this is the first time I’ve gotten into a discussion about rates/converters in like 5-6 years.
Like I mentioned...when the initial debates were raging several years back, in the early 2000’s...I picked the 88.2 rate and kinda' stuck with that. I will reconsider my choices again if/when I change out my rig and go for different converters…and thanks to this this discussion, I will probably reexamine my existing converters and sample rate choice before I start a new project.
But to answer your question…where I HAVE seen the higher rates almost always promoted, is in just about every audio magazine…in articles/interviews and certainly in manufacturer ads!
I mean...I don't recall any articles/interviews/ads saying point-blank that higher rates will yield *better sound*, but they all seem to point out the higher-rate capability of their converter, which sorta indirectly promotes the higher rates as better, and that fuels the myths.
”Model XYZ now has 192kHz capability”…or...
“We used the new XYZ converters which sound absolutely pristine!” Of course, in the ads, XYZ manufacture touts their new 192kHz capability, and so people just connect the dots!
Not to mention, there HAVE been “pros” who for awhile there were openly swearing they heard sound improvements with higher sampling rates.
I dunno…maybe these days many of those “pros” have stepped back from their previous views…but the ads/articles in most audio magazines still point out the higher rates as a key selling point.
I mean…I really can’t recall any ads/articles/interviews where higher rates were actually labeled as
unnecessary…though yeah, there have been debates on both sides of that coin on the forums, so this is not the first time I’ve heard the arguments about there being no need to go above 44.1…though almost all of them will qualify that statement by adding
“with properly designed filters/converters” after they say
“44.1”.
And maybe it has someting to do with...
don't do like I do...do like the ads/gear I'm endorsing...!!!
So while I am not looking to continue to “give credence” to higher rate beliefs

…I am pointing out that
taking into account the variety of converters that are out there…there may(?) be those that actually DO sound better when they are switched to 88.2/96
because their design/build just makes it work out that way.
Don’t you agree?
What also makes it hard (and fuels more myths) is the fact that these days, the majority of “recordists” that have some form of converter box in their studio, probably leans heavily into the non-pro studio arena…which means the odds are good they ain’t using any $5000 converter.
So yeah, for them, the more realistic answer may be to just TRY both the higher and lower sampling rates on THEIR converter box to see which one sounds better (due to the design/build of their particular unit). OK…that MAY seem like it’s again rubbing against the known science…but I just see that as “in-the-trenches” reality.
While we can read about Bob Katz and others who have the high-end, esoteric toys, where theory and science meets reality…the majority of “recordists” may not, so for them the reality is to try it a few ways and go with what they think sounds better.
IWO…you can’t just go on faith that 88.2 doesn’t sound better and/or is not needed…if in fact for a
given converter box it does.
Can you…???
You know…we ARE in total agreement on the fundamentals…

I’m just suggesting that there is no obvious answer when you consider the many converter designs that are in use. Who knows which “target sample rate” was in the blueprints for the overall design of a particular converter?
