Pink Floyd - Dark Side of the Moon - Analysis

So then the 2000 in your nym represents a very long lineage?

 

Thanks! foobar.

 

Nice work!

Thanks Foobar2000.

 

If you wanted to make these spectral comparisons even better, you could use the average spectrum of all seven versions (after normalization) as baseline, instead of picking one version more or less at random. It'd be even more objective.

 

Actually it's stupid nym, not sure why I chose it. Great prog, but I could have been more creative.

 

Interesting idea. I'll give it a try. (Have to wait for this evening tho.) We may have to throw away the odd balls, like the 1984 EMI and the 1985 Capitol.

 

I think the best would be to have the master tape's spectrum as a reference. Not so sure about the average curve for a bunch of different masterings though...

 

Agreed, but how?

 

Give it to fb2k for a day ?

 

I think the “Money” 1993 (Sax) Normalized chart almost does that. The similarities of all the masters between 100 - 4k is rather striking and leads one to believe that is the closest to the “master” (for freq. response) as we’ll like ever get.

But having an average as the baseline would still prove even more valuable (back to work Foobar).

 

Foobar, excellent work without any alterations needed. Still unsure about the DR statistic. Isn't this also affected by frequency band equalisation?

 

Sheesh, and here I just got home from work.

 

I just tested the full-track (as indexed on the CD) of Time from the 1983 Sony. Just because I had both the original as-ripped file, and the de-emphasized one, handy. For those of you who don't know that's like applying "frowny faced" EQ to the high end of about 10 dB. (That's a lot!)

Original un-modified rip has a DR score of DR13.
De-emphasized version has a DR score of DR9.

That may be an extreme case, because the big peaks are in the alarms at the beginning of the track. But, yes, EQ and no compression can affect the DR score.

 

Arighty then, these are all normalized based on the ReplayGain numbers for the actual clips. (Not the tracks as indexed on the discs.)

Money raw spectral data with the average plotted:


Just for comparison sake, with 1993 Sax as the baseline as before. Note that this is zoomed in a little closer then before:


Now, using the average of all seven as the baseline:


Because the 1985 Capitol and the 1983 EMI are so clearly different I figure that likely they are not "flat transfers". So this is using an average of just the Sax and the two Guthries as the baseline:


IMO, interesting, but not really any earth shattering revelations when compared to just using the 1993 Sax as the baseline. Sax and Guthrie still look closely related, and the other four still retain the same character.

Remember that this doesn't prove which is "right" or "wrong" compared to the master tape, just showing how they differ from each other.

 

Now, the same as above, but for Time:









Whew, you guys satisfied now?

 

Never was an audio techno-geek, but I feel left out when one of my favorite albums is being discussed. Some day someone is going to have to show to me how to read these charts and graphs and explain to me how they relate to what I hear. Some day.

 

Only if you can repeat this performance after the WYWH Immersion is released.

Of course, you could do it now with the redbook, but I understand .......

 

LOL!

 

Conclusion?

the best cd release ever is?

 

I plan on it. That's the release I'm most looking forwards to.

 

The one you enjoy listening to the most. . . .

 

Sorry, that was a typo. I meant DR values, not EAC values.

I remember reading an explanation of the TT DR algorithm when the software was released a few years ago. Apparently it picks the loudest 20% of a file (where compression and peak limiting is most obvious) and measures the average dynamic range in that bit of the song.

 

Certainly. Thanks!

 

Foobar, maybe I overlooked it in the nearly 100 posts in this thread. Did you apply de-emphasis to the 1983 Sony version? That mastering has pre-emphasis and will not have the proper EQ'ing if you use a straight digital audio extraction.
