Honestly I would just ditch the De-Emph script or whatever and do it by ear because the other way is simply not accurate according to my samples. The results speak for themselves.

You can't use your analogue rip as a benchmark. From SoX - Sound eXchange...

"A typical CD deemphasis circuit of the time might be out by as much as a dB."

So de-emph filters are regarded as more accurate.From SHF...

"To my ears SoX is the most transparent way to do it. Even better than any CD player's de-emphasis that I have heard."

You suggest the uploads using Sox are closer to yours than mine.From SHF...

"The Foobar IIR filter also uses SoX and I agree it is great."

...and...

"In the wiki - http://wiki.hydrogenaud.io/index.php?title=Pre-emphasis - the following is stated:

"WaveEmph, SoX, and all of the foobar2000 plug-ins have been tested and produce nearly identical output. The differences are minuscule and inaudible."

Conclusions:

Any differences in results using plug-ins are NOT down to one filter being more accurate than others.

So any CD rips using the leading digital de-emph filters will be accurately de-emph'd. So we must assume any difference in various digitally de-emph'd rips must lie elsewhere. Different pressings? There were at least 2 variations of the japanese pre-emphasised Abbey Road (I may well try using foobar de-emph on the raw upload from yymca6 and see if it produces a better sounding result).

Analogue rips can not be guaranteed to be quite as accurate. Because of possible inaccuracy in the players de-emph circuit as noted in the discussions on SoX - Sound eXchange but also let's remember there a small degree of amplification by the player and (if recorded thru an amplifier) a further degree of amplification by the pre-amp. All CD players (if using the analogue outputs) and all amplifiers sound different so analogue rips will sound different depending on the equipment used. Basically a further EQ difference is introduced. So we cannot use an analogue rip as a benchmark.

"Honestly I would just ditch the De-Emph script or whatever and do it by ear because the other way is simply not accurate according to my samples."...No! That is clearly not correct as demonstrated by above. If it produces a result you like as your listening copy great. But not as an accurate rip of the original source.

Thanks paul62 for all of this!

Your de-emps are closer to my live rips and, yeah, they may have one or two decibels less treble than mine that sounds about right. Paul's de-emph sounds nothing like either of ours they sound VERY muffled like shaved off above 15khz. I just played them all again side by side again. I can still hear up to 17khz. Clearly one de-emph method is faulty. You guys need to like actually use your ears and stop trusting those darn scripts as your objective truth. There are now THREE versions posted people should listen to each side-by-side on a full system (not computer speakers!) and make an objective opinion which sounds best or most closely matches a real CD playback. With that I'm out of this discussion. Please don't throw EQ charts and SHF quotes at me either I'm done. Cheers.

Has anybody got a rip of the de-emph'd black triangle abbey road they are willing to share?

More than anything else, I'd prefer to think of my AR uploads here as recreations of the tracks from the Pro Use LP (as played through my hi-fi system, with whatever tonal anomalies or differences that process gives to the signal output): bringing up the matter of the Black Triangle CD's status as a pre-emphasis/de-emphasis kind of CD is meant to create some interesting debate and discussion.

You're very welcome, my friend! It's a shame that I can't offer you a bowl of my chicken soup, though!!

Enjoy the soup! Maybe one day we'll be able to upload food and recreate it with the help of 3D printers

Aha! The de-limiting setting for the 2009 remasters! GOOD one, paul62!

Thank you Paul, another gem for my collection!

Yes, as great as Paul's new version sounds, I'd also still like to have this as well for my collection (my FLAC files are NOT de-emphasized)...
