"Greening" a CD...fact or fiction??

wow.

I agree, smellyfuzz, it is difficult to quantify the aesthetics of a green ring on the perimeter of your CDs. Ya got me there.
 
Fuzz,

I don't think that I can explain it to you again any differently....

This is what a digital stream might look like:

1010010110100111

There are only TWO possible voltage levels, on and off. When this stream of bits hits your D/A converters it turns into an analog stream that you can actually listen to.

If two identical streams of bits come into a converter, then they are indeed IDENTICAL. 1001 cannot sound differently from 1001. They are exactly the same to the converters. You can't hear the difference between the two...not because you don't have good ears....but because it is truely, undeniably, physically, universally, IMPOSSIBLE. I'm not making this up...I'm not guessing...this is a well known, undisputable fact. It is in fact precisely WHY "digital" exists.

That's not saying that a lousy converter won't change the way they sound, or that your analog cables won't change the sound, or that your preamplifier won't effect the sound, or that your power amp won't effect the sound, or that your speaker cables won't effect the sound, or that your crossovers won't have an effect on the sound, or that your speakers won't have an effect on the sound, or that the conditions of your ears won't have an effect on the sound. That is 100000% besides the point dude.

The only way that greening a CD could change the sound would be to change the bits. Greening is a modification to the digital SOURCE.

10010110 - Green
10010110 - Not Green

You can't tell the difference between those two sequences of bits. Neither can your ears. They are exactly the same to your D/A converters. EXACTLY the same. You might hear a difference based on environmental and other variables in your system, but these will be random in nature and are not in any way dependant on greening your CD.

The only way that greening a CD could help is if stray light caused enough errors that it defeated the error correction mechanism of your CD player. Note, the error correction "mechanism" is not a guessing game, it is mathematically true. Errors that cannot be corrected are still detected. As was demonstrated by the Ranada article, there was no difference in the error rate of a greened CD.

If you don't understand how two identical digital sources cannot sound differently under identical conditions, then I don't know what to say....it's like arguing that that sun revolves around the earth.

Has anyone tried this with the REM " Green" cd yet? Or anything by Green Day? There must be others as well. Was Green Tambourine ever released on cd?


(Sorry, It seemed like people were kinda nodding off.)

Will this war ever end????

Audiophile vs Engineer......

I want to make three things clear.

- I personally don't believe in some of the tweaks I've seen posted here.

- I did NOT try to start a damn war here - my intention was to get opinions on "greening" which I have done - and I have drawn my own conclusions - right or wrong.

- drstawl.....I was kidding man!! Your avatar is FINE. Don't change a thing. BTW...I was not hung over I was still DRUNK. (You ever take a two year old to the circus...;) Damn good thing my mrs drove!! )

I have learned FAR TOO MUCH from this board to piss anyone off...so I hope I have not already done so.

peace and out...

Too bad zip. When you start a thread, you have to assume all responsibility for everything said in that thread. So smellyfuzz and I are off the hook, and YOU'RE the bad guy! Thanks a lot jerk!

:) :)

why not jus record the scratches of an old lp and alter the wave to death ?
btw i use green cds
 
Whass Uppp Slackster????

"YOU'RE the bad guy! Thanks a lot jerk!"

Damn....rough crowd.......... ;)

Oh well - I accept FULL FRICKIN' RESPONSIBILITY for my wanton disregard for the thoughts and feelings of others.....I will never post again....

yeah - right....... lol

Good, I was sick of you causing all these problems! What's next, a PC vs. Mac debate? You are one troubled dude.

i have realised through reading posts no the web that audiophiles seem to be english teachers in disguise. they are all anal retentive and think that what they heard is correct. have you ever in your life tried to state your own point to an english teacher? they will not believe you, or even credit you of having made an intelligent remark. uncanny the resemblence to audiophiles.
 
or a business comm teacher for that matter.

"you just can't use this cliche or that opening" or this or that. why? Cos it JUST NOT done in business writing.

Well, thanks a lot. What a limp answer-just not done. Who defines what is done and what is not.

Those teachers. hmm
 
No matter how much you talk about "subjective" and "binary" and all kinds of other differences, there is one cold hard fact. Any difference will be based in science. That is unless you are living in another demension where the laws of physics are different. And all of these differences can be measured and proved or disproved with science.

Sitting in your living room listening to the difference between the brick on your cd player and not is VERY POOR SCIENCE. This is why scientests use double blind tests. Knowing if you are listening to a cd that has been greened or not will color (sorry) your judgement. Ever wonder why placebos are used in medical testing? So nobody will think that they are getting better because they are taking the pill. The tests are double blind because even the people administering the test don't know which is which. A 3rd non-interested party is used to distribute placebos and the tested item. This is the the most fool proof way of testing used. PERIOD. If you can come up with somthing better than double blind testing then you are one of the smartest men alive.

I would love to come to your house and administer a double blind test of the green cds and the $.60 thing and the brick on the reciever.....

It's easy to claim to hear the difference but proving you hear a difference is a different story. If your ears are as "golden" as you claim, then you could prove all of us wrong, but imho, you will fail as miserablly as the great audiophiles in the past in real scientific tests.
 
Ok, I can't believe I just sat through this whole thread. I had been avoiding it, but I just read it all in one sitting and - YIKES. I got a few funny looks because of stamping my feet in an effort not to scream (being at work and all)

The bottom line is - digital is digital. Once it is off the CD, before the D/A's, it is just 1's and 0's. No .5's, nothing. 1's or 0's. High voltage or Low. If the error rates are the same and if the ripped tracks have the same set of 1's and 0's before and after greening, if you run the result through the same D/A's, you WILL NOT HEAR A DIFFERENCE. No matter how expensive the rest of your system is. 10101 = 10101 always. That's just the way it is. And if the bits don't change, the sound don't change - or if it does, your D/A's are fucked since they would be changing the sound randomly.

Well, let me rephrase that. If you don't know which is which, you won't hear the difference, since biases will screw up subjective tests. That's why scientists use double-blind studies in the first place (btw, for those who don't know - a double blind study is one in which neither the person doing the test nor the subjects know which is which - the tested objects are identified by numbers and only decoded after the results are in)

The point about "Why don't the random errors ever IMPROVE the sound" is a good one, though
 
Greening, maybe not.. but I definitely believe in "browning" CDs at certain times.
 
pglewis
I went to that sight but I couldnt stay there cause I had a needle poked through my side at the hospital today and it hurt to laugh and It Is A Great Site. I gotta go back; didnt click on anthing but I gotta check out that
powerless cable, I always wanted on of those suckers
and if the price is right I'm gonna git me one.
 
sicko??

"You are one troubled dude." d00d you have no idea ;):)

I have learned the following so far...

- Green bottled beer is by far the best
- Green ink must be placed on the entire edge
- Green ink must be special green ink
- Greening a CD may or may not help - indicate A or SE
- Green Bud is Good Bud
- Green is required to buy what you need to green (a CD)....or not... but is what you need to buy the good equipment you need anyway
- Greening cannot effect 1s' and 0s'
- Green CD's were said to be used
- Green Paint helps improve the sound of your woofers
- Green "special" paint it must be
- Lt. Green (phthalocyanine dye eg Mitsuis') are best

and...

- Greening is fact.
- Greening is fiction.


Wheuw....did I miss anything?

btw...I heard a Mac sucks so bad - Apple had to develop a special "greening ring" to warm up the data stream for audio applications.....;)
 
hi vox,

I have not tried green tissue over ns10ms, but I think I read somewhere that pink tissue is the best, because it minimizes phase problems.

I suspect that green tissue will cause me to mix bass heavy, because it is so cool, while red will cause you to mix trebly because it is so HOT.

By the way, have you ever slept in a green room. Much easier to fall asleep

Also, try this and be amazed. Sleep on a green bed. You will not be able to feel the bed. THe bed becomes no existent and all you have is beautiful sleep. Also, it absorbs light better, so stray lights are not even noticeable. : )
 
CJ.....

Green BED??...why that's absolutely silly! Everyone knows green sheets are the key !!

If the bed were green and the sheets were white there would not be the critical "green interface" area where the body actually meets sheets ! Same goes for the green comforter / white sheet combination. No interface = no net effect....

Sheesh !

LOL zip,

You are correct about the green sheets thing, but I tell you, If you buy a green bed, you can't even feel the bed.

Its uncolored, it leaves no artifact of its own..

But your room has to be resolved before you can feel this state. THat means green bed, green walls, green bud, AND gree sheets.

peace
