HD FILES which is best hi Bit Rates, or Hi Word lengths?


Greetings all,

It doesn’t take long to see 24/192 & 24/96 lossless files are the standard for High Def PCM audio, albeit, some hardware now up samples the bit rates to soaring levels for proprietary reasons.


Consequently, we’d all like to have both bit rate and Word lengths as tall as possible when originally cut, but now and then there is a definite disparity from several online resources wherein the words are long, but the bit rate is low, ie., 24/44.1K, or 24/88.2K.


… and we love the content! Which pretty much settles it for me, but being a picky sort I thought to see what some consensus was on this subject.


As such, it can be a bit costly to keep buying albums whose words and bits differ radically from the presumed standards. Especially if the supposed HD cuts are but marginally better or not perceived as better, at all than what one could rip . from CD


One EX would be the current HD Tracks download of The Life Songs of K Kristofferson a live Tribute album that is simply outstanding and releasedOct. 2017 . It is available as a 24/44.1K file.


Ripping off DVDs one usually can’t get beyond 16/48K when snatching 2 ch audio tracks. New options in current software enables artificial or just after the fact upsampling of the BRs.


So what should count most? Higher word lengths or higher Bit rates, when one or the other is not necessarily high or as significant?


Is this a black and white issue?


Wait for a higher set of numbers on the files you want, or dive on in, buy ‘em, play ‘em and see if they were worth it?


Lastly, does upsampling via software a true way to improve fidelity or sound Quality, or is it merely just one more placebo one can take to satiate themselves emmotionally?


I always felt if there were untoward issues in the present recording upsampling isn’t gonna improve things. But I’m always willing to learn new stuff or replace stuff that just ain’t so that’s already in my memory banks.


Thanks much for the insights.

The key is to understand that most DACs benefit from higher resolution and upsampling as it corrects non-linearity in bit levels and allows for a less aggressive anti-aliasing filter.

Currebt Class A+ DACs have the equivalent of 21 bit resolution at the analog output. It makes no sense to restrict yourself to 16 bit if a 24 bit version is available.
A bit of both is probably the best answer. How much that would be audible is a moot point, however. If you think it will be, make sure that the tracks are really HD. Also, don't waste money/disc space on HD versions of old analogue recordings.

Blindjim > @shadorne > for this question then, merely look at the apparent Word lengths as indications of better sound quality and resolution? Not necessarily the bit rates?

BTW… what’s happening to those other three words from 24 to 21, if you don’t mind mentioning it?

Blindjim > @Willemj what methodology do you use to ensure tracks you’re considering buying are in fact High Definition?

Willemj > don't waste money/disc space on HD versions of old analogue recordings.

Blindjim > this one I sort of get. Old master tapes by their nature seem either hit or miss as to their orig integrity, so deriving greater fidelity off of them simply by now converting to higher rates doesn’t seem to add up.

= = ==

In spite of that last sentence, I mentioned to a friend the other day that folks are re-issuing supposed HD digital files taken from the orig Master Tapes and as well providing reputedly better quality audio onto 15 ips Reel to reel tapes too and both formats are a lot more expensive.

The question he posed then was “how do you get better sound quality . from a decades old orig master tape than what it already possesses?

The debate then hinged on if it was analog to begin with, how did it improve migrating into digital, than back into analog as with LPs and reel to reel tapes?

Trying to answer, I said, “digital trickery.’

It was the best I could come up with then, I’d like a better more qualified answer if possible from folks around here.

As Willemj said, ensure its HD at the oneset. OK. How?

Some of the prices I’ve read about on these forums for RTR dupes of master’s can bring hundreds of bucks. Seems to me it’s a pretty easy place for someone to lose a fair chunk of money, as there seems no possible way to validate the product beforehand.

Ditto, HD retail files quality from archived masters of years gone by.
