Re: [SurroundSound] Re: Bit Rate Resolution, Sampling Rate, Upsample, and Lossless vs. Lossy ....

Just read an interview with Bruce Brown on Audiostream.  Here's the relevant quote you made me think of Lokk:
"For analog master tapes, we have captured bias frequencies on tape as high as 150kHz. If a tape can contain frequencies that high, that's "hi-rez" in my book."

I am not a cheerleader for either side.  It is mastering that makes the most difference.  I've heard DTS of say Pat Metheny (i probably butchered his name) that sounds better than almost anything lossless I have.  Same goes for Lalo Schifron (boy im going to catch hell for not spelling these right).  Gillian Welch makes magic in 16/44.  Black Keys make an artform of compression.  Not music to my ears and 24 whatever is still compressed so high res is not at all helpful to them.  Brothers is a great example.  The DTS of Young Americans is nearly faultless so even lossless music can be made very well.  I'd prefer anything that is mastered well in any format.  I've heard sublime SACDs.  I've heard some that sound worse than a CD or cassette for that matter.  I've heard some of apple's compression scheme and must say for some music it does not sound bad at all. Not my cup of tea but it goes to show that anything can be made musical if the intent is to do that from the beginning.  So I will always sit on the fence and enjoy the best of whatever music comes along.  Sure, I prefer good high resolution copies if they benefit the experience.  High res Black Keys?  Not a whit of improvement.  Norah Jones newest?  High res helps the overall loudness of the CD version and makes it less distortion prone at higher volumes.  Nice, but small improvement.

I don't even know where in the the thread that 1970's analogue tape
recording was mentioned but perhaps it was in making the point that
96/24 and indeed 192/24, go a long way to capture that "sound" where
perhaps (caveate - to my ears) RBCD never did and lossy never will
do.
Cases in point, DSOTM, WYWH - 70's analogue tapes that do sound better
at higher res to most folks - see all the discussion on this last
year.

Mastering to me is just where in the master chain that you define -
that you stop messing with the original signal. DSOTM was case in
point. The Guthrie mix appeared to adjust the digital masters at multi-
track source (kind of later denied) and ended up with a pastiche of a
mix which many folks on this forum complained about, perhaps you too
if I remember Brian?

Perhaps the reason that, and this is a generalisation, knowing some
awful analogue mixes, some analogue recordings are so cherished is
because care had to be taken of qualiity (of recording) over quantity.
My TEAC X-1000M (not the best R2R) cost around $1500/£1000, twenty
years or so ago which would be, 5 times more at the equivalent cost
today. This was a stereo master mix-down machine for the normal
impoverished studio. Today my HTPC can handle 48 track mix down like a
multi track machine and costs less than a grand  and still do the mix
down - it means that track quality is not a priority and so studio
skills are now aimed at getting sounds out of little boxes and ear
buds not hi-fi nuts like us.

As a Stevenism (Sorry Steven I'm becoming one of your supportesrs so I
joke)  96/24 gives and un-filtered bandwidth of 48khz before any of
the Nyquist/Shannon laws apply. Therefore 22khz is there if it's not
removed.

So to my point; I'm a firm believer in digital too (listen to early
digital like "Swing of delight" [what bitrate/frequency?]  by Devadip
Carlos S on CD and vinyl) but as ever source is so important, and
perhaps this is what  drives the great sound debate more than anything
(apart from DNR which has set hi-fi back years). Some of my favourite
listens are AoQ's R2R recordings that have such a pure simplicity
( Simon & Art BOTW)  that they make some of the latest HR downloads
sound sterile. But guess what - these are simple source recordings
taken with lots of care.
