Neil Young’s new audio format

Reply #225
While many take issue with the amount of DRC on Californication, I suspect the true issue at hand is audible clipping.  There have been subsequent casualties of the loudness war, but all we hear about are the same tired examples. There are plenty of titles with lower RG and DR measurements people don't complain about. I suspect it is because the audible clipping isn't as pronounced.

A recent AES study quoted on this forum suggests this phobia may be overblown.

I think it's time we have an honest discussion about the advancement of DRC over the last 15 years rather than this shallow, knee-jerk vitriol I keep reading.  This isn't the proper topic for such a discussion, however.

It has the full package, lots of DRC, lots of clipping, and on top of that it's basically a mono record. I can't remember noticing any stereo separation.

The last time I saw AES studies quoted was in the amir-thread, and those were not worth the paper or PDFs they were printed on. Let's say I'm wary, AES seems to be the sock-puppet of music hardware companies. Fool me once, shame on you, fool me twice...

It seems you may agree that the post I followed didn't adequately characterize the album.  The DR may be bad, but today titles have half as much but with less clipping.

Regarding AES, someone is doing something to study the audibility of the phenomenon which is a lot more than what is going on around here. Ironic.

Then he goes on to talk about Phillips and how he has FACTS about the compromises made that make CDs inferior to hi-res music, but he doesn't back his "facts" up with any kind of references.  He does not provide the names of any Phillips enigneers he spoke with, nor does he provide quotes from any publications or even his own emails.
It's historical fact that the pioneers of digital recording chose 48kHz or above.
http://theartofsound.net/forum/showthread....-Audio-Recorder

It's historical fact that 44.1kHz was chosen to fit onto (betamax) video tape.
http://www.cs.columbia.edu/~hgs/audio/44.1.html
Though the notes with that calculation are misleading. Those numbers aren't the number of "active" video lines, and VCRs record inactive lines anyway. VCRs do however trash some of the lines just before the VBI (at the bottom of the picture), so obviously you can't store data there. There is also an eight line section within the VBI that you can't mess with. Leaving a sensible amount of space, and keeping the bandwidth requirements easy for Betamax and VHS, gives you those numbers. You need a better video format, with higher bandwidth, to get much higher (e.g. 48kHz, 50kHz etc).

The concerns at the time were over analogue filters. I read these as engineering concerns, with the possibility of audibility - rather than a sense that it would sound awful. Many of the critics seemed to prefer the sound of analogue tape over the sound of a live microphone feed, so they were never going to like digital.

Cheers,
David.

Pedram Abrari, EVP of Technology, Pono  explains the cause of the 'loudness' wars.

Quote
Since much of the nuance and detail of the the artist's creation is lost and never heard in a compressed format, this resulted in an apathy up the music creation and delivery chain, all the way back to the recoding studios. ...{snip}..... Music was further damaged due to the unnatural manipulation of its dynamic range to compensate for lack of audio quality. It was recognized long ago that people perceive loudness as quality and to make up for the poor audio quality due to lossy compression, the entire dynamic range of music tracks were made loud and this was the beginning of the "loudness wars".


His "theory" is so flawed, I wonder what lame explanation he'd come up with if challenged, to fit it in with the fact that an album like Californication, with its notoriously crappy dynamics, came out exactly at a time when MP3's popularity was still taking off.



These poor souls are just casting about trying to come up with a plausable justification for a solution that is looking for a problem.

I lately linked to that hard clipped album Sean Rowe Studio Master clipping
Besides it clips hard and measures low dynamics it still sounds surprisingly well. Not because it is 24bit but there are good captures of his voice and the rest.
Also i wonder when people dig out the DR hammer when comparing new masters to the old cd. Many sound clearly better even when the DR number lowered. Some early Tom Waits for example sound loud but beautiful as remaster.
On the other hand there i checked Tom Waits "Raindogs"  2009 SHM cd that sounds worse. IMHO there was no real effort made but the old data just bass-maximized and compressed.
Is troll-adiposity coming from feederism?
With 24bit music you can listen to silence much louder!

Well aware of DR only being the tip of the iceberg regarding the issues found on that particular album, the reason of my bringing it up was simply to point out its release date clearly discredits Abrari's theory that the loudness war is a by-product of engineers having to adapt to the limitations of compressed formats.
That is, how could it be if Californication came out before MP3 became really popular?

You got me and hit the nail on the head, Arnold.

You could have mentioned Dirt by Alice In Chains: same DR value (FWIW), released seven years earlier. Loudness achieved by more primitive means. I raise it for a few reasons, not least of which it being the first time I became aware that something bad was going on with a perfectly good format.

Some people at AES and engineers in question try to divert the attention from the fact that people's production decisions are the reason of the decline in audio quality. They rather put out studies about "hi-res" audio and other red-herrings.

Why some people still argue that there even might be technical or technological reasons behind the loudness war is beyond me.

"Neil Young's PonoPlayer: The Emperor Has No Clothes"

In the wake of recent fairly-well written articles by the non-specialized press, this one by David Pogue IMO, clearly stands out. Even more so when you realize he's gone as far as conducting a double-blind test with (apparently) third parties that are real laymen, not self-promoted specialists and/or audiophools.

Ok, it couldn't come without the odd faux pas such as:

[AAC is] much better than the radically compressed MP3 files of 1998.

and

Clearly, if Pono’s testing involved a remastered, high-resolution audio file going head-to-head with an original, crummy MP3 of the same song, you’d hear a difference.


Anyhow, let us expect these last real eye-openers of articles for the general public we've seen lately, to become, if not the de facto standard, at least more and more frequent; as for every Mikey Fremer's strongly-biased hodge-podge of lies, we surely need more Chris-Kornelis and David Pogue-like sober studies (properly backed up by genuine sources and empirical facts, not just name-throwing) coming out from the generic press.

So I wrote to Pono — and heard back from Neil Young himself.

“Of approximately 100 top-seed artists who compared Pono to low resolution MP3s,” he wrote, “all of them heard and felt the Pono difference, rewarding to the human senses, and is what Pono thinks you deserve to hear.”

Aha — there’s a key phrase in there: low-resolution MP3s.


So the reality of Neil's test was more like " ... all of them found first-class rail travel to be more comfortable than a bicycle?"

I wouldn't bet an arm or a leg on it.

But, thinking of the public it's directed at, I think there are some other more important merits to it, such as making some of its quite-possibly uninformed readers more DBT-aware when it comes to subjective quality and maybe even more aware of the truth behind the miraculous claims regarding HiRes audio.

To be fair, it's possible to interpret the original quote as meaning the "obviously inferior" MP3. When you've taken the stance that your format is superior, that wouldn't be an unreasonable logic. Not that I'm suggesting much credence be placed on it, since without specifying exactly what was compared and how, the statement remains useless.

Without introducing extra devices in the signal paths the crude volume steps of an iphone and a Pono wouldn't allow for the precision necessary, even if external instrumentation was introduced to measure the two levels, as it should. This is even true with modern day AVRs, for that matter.

I also don't think the test was DOUBLE blind, song time synch was by hand, and in the still image of the Radio Shack switcher the two incoming RCA cords are visually distinguishable, although he may have done the swapping at the other end.

I agree with your logic, definitely. But one thing that makes me think it's plausible they used low quality MP3s is that, I think every time I've encountered them, when the vendors of "hi-res" music make their comparisons of formats and their data rates, they consistently list 128-320 kbps as the common bitrate of MP3s you can buy. PonoMusic does this as well. But is there anywhere actually selling 128 kbps MP3s these days or in the past several years?  I know it's used for previews on websites like Bandcamp and used to be the standard rate before hard drives got big, but I don't think anyone is paying for 128 kbps MP3s anymore. I know iTunes originally did 128 kbps AAC, but they switched to double that awhile ago. I wouldn't be surprised if they used 128 kbps CBR MP3s, encoded with iTunes or Windows Media Player, in their presentations to artists out of the mistaken belief that that's actually something common. The number of audiophiles who think you can buy MP3s on iTunes may be a good indication of their knowledge on this topic.

Or they dug up a copy of Bladeenc and used it to encode at 128kbps. I'm pretty sure a dead deaf man with feces in his ears could ABX those 100%. That encoder at 128kbps was an exercise in auditory pain. If I was an unscrupulous guy wanting to pawn my audio snake oil, that's how I'd make the mp3 I used to demo how much better my stuff is.

There's an ongoing video series on Youtube by Ian Shepherd regarding loudness and compression, which I found interesting:

He has a bunch of other videos on the loudness war on his channel, too.

CONCLUSIONS AND FUTURE RESEARCH

We failed to find any evidence of the effects of dynamic
range compression on subjective preference or on
perceived depth cues. Our perceptual data suggest that
listeners are less sensitive to even high levels of compression
than commonly claimed. This indicates that the
much-debated perceptual effects of compression used in
mastering are related to more than lower peak-to-average
ratios per se.

Future perceptual research is needed to examine
more complex interactions with other remastering
techniques typically combined with compression (equalization,
mid/side-processing, etc.) and with the particular
design of compressors. For instance, spatial treatment to
enhance the depth field may counteract potential effects
of lower peak-to-average ratios on spatial cues.

It also remains to be investigated whether specific distortion from
+0 dBFS peaks affects spatial cues and preference, and
whether dynamic range compression may have different
impacts in different playback situations (for example, other
playback equipment, playback environments or listening
positions).

Perhaps, but in the language of the industry, these days, hasn't "resolution" become synonymous with sample rate and bit depth? Isn't the sales pitch that it is sample rate and bit depth with determine resolution?

The language that some use differs from the science.  Resolution relates to bit depth, and sample rate relates to high frequency bandwidth.  This was all pretty well worked out, published, reviewed and agreed upon by the end of WWII. Some people are a tad late getting the memo.  Nothing new! ;-)

Yes and it was already discussed.  You could call it an ABX test if you like, but it was horribly flawed to the point of uselessness.
