Copying discs with high frequencies

Hello!

Just starting to delve into the topic at all...
Read a little, listened to -like, just not dangerous...
Now I want to touch on the topic of rewriting....
Don't want to affect the rights of the author, his honor and praise!
Buy a license of course! But the rewrite is convinced it is possible without problems...
Music of zeroes and ones called...
Unit - adjusted laser-disk space, zero - the laser is not affected...
For example: if you copy at least one bit is not prescribe the program will not start.
For this, I dare say that when you copy the disk information is not distorted if you do not convert, etc.
Book without problems, respecting the rights of the author!

Andrei Patrushev sincere respect!

Yeah, I thought so too until you began to really copy...

Yeah,me too.Why the effect copied version is not the same as the original (objectively,without pressure on the retaining copyright).

Program UltraIso allows you to copy data from the audio CD as wav file.
For purity of experiment with copying CDs need a good digital player (not the disc) in which you want to upload a file read from the original file read from the tenth (or even second) copy, then browse through audiostrobe what happened. Are not able to verify because of the lack of audiostrobe.

Hello.
I also have a question on copying, but a few "unusual". I myself am not strong enough in how to protect data on CD against copying, and therefore want to find out the veracity of the rumor that when copying turns out, not only low quality versionbut the original CD is also broken. The seller explained it to some "holographic gearing"

Thanks for the reply.

I think that the stamped blank,which is the original disk cannot be changed.

Thanks for the reply.

In nature there are discs 1-2 listening, then they are stupid "dying". But, to the expanses of our vast country, this insanity has not yet reached. Hardly anyone in here would buy such a disk.
And, disks, a copy of which may be poor quality - is.

If you mean "Forecast", this ONLY applies to disk "Weather" one. Drives Patrushev is not relevant.

It was interesting to read about the fact that the first photo was taken from the same file will be more beautiful than anything made after from the same file.
Laughed for a long time.
Now I understand why vordovsky file is the more often you open it to read the font from bad to worse.
But seriously, after the transfer of analog sound with the Telefunken in the figure, the talk about the deterioration from the evil one.
Here in food, Yes - there is indeed the first piece bitten off from the same ham will taste better than bitten off later.

Question slightly off topic, but I wonder this curly noodles from manufacturers or it has adherents in the religious impulse, is produced.

if when overwriting with a laser lost zeros and ones then the quality probably will drop ...
rather, quality is lost when parazitii and when incorrect codecs ...

question : if disk not copy to another disk and on the flash drive ?

question : if the effects of disks Andrew so sensitive on what headphones and what kind of player they need to listen ?

whether to squeeze the headphones to the ears ... because then the quality varies greatly ...

does it matter soft or rigid headphones as they appear at different vibration ?

thanks in advance for answers

I copy disks CloneCD (about it already mentioned),
the trial version works 30 days, enough to make a copy.
The only program which is doing data analysis (almost reading between tracks).
And can write on 1st speed.

I copy made for myself. At the hearing they are the same, but still listen to the originals.

For interest tried to wrote something in the Internet on pirated sites is. He has recorded several discs from different sites (torrents) the same disk. While playing, they differ to the ear

Who knows what they "robbed".

This theme carries the mystery from a mile away. Audio CD - the digital music, it will either read correctly or not read. Even if it is written on cheap drives, and the signal is so distorted that a possible false interpretation(which is unlikely, signal patterns are as different as heaven and earth, and soon you will receive an error reading, which works nieoficjalny mechanism), in this case, it will work correcting codes reed-Solomon and the error either will be corrected, or in worst case detected.

A possible difference in sound can be attributed only to temporary delays in reading expensive copy disks, but even in this case, when you copy the disk to a file, the copy will be identical - there is a time delay in reading the curves of disks does not affect.

the Unit is adjusted by the laser spot on the disk, zero - the laser is not affected...

Even if zero, the laser still registers, but with different power. It is a common misconception in the digital technology(including laser technology) zero signal NEVER corresponds to no signal as such, there's always a level of zero signal that is not equal to the physical zero. The zero level is determined either by the execution circuitry either from the standard.

For example: if you copy at least one bit is not prescribe the program will not start.

Too not the fact... the Probability that a bit will be spoiled for the copyright inserted by the linker, text data, or just at the end of section\page, which saplan zeros or just garbage, pretty high. And even if the affected code, then perhaps this is a very rarely used procedure, or perhaps the presence of an exception handler. What will happen will not work properly - very possible, something that fails very rarely.

But, despite my amendments, with You, the namesake - Eugene Payusov, I completely agree. Yes, the technology of the printing discs is very different from burn, but the content... - is doubtful.<

Will contribute

Always believed that well-made copy needs to be absolutely similar to the original because 0 and 1 in Africa and they are 0 and 1.
But, finally becoming the owner of several original discs, I had the opportunity to compare the copy with the original.
While compared Healing.
The original is better tocause is heard-clicking sound is almost on the verge of audibility (probably signal audiostrobe)
Rechecked 5 times.
At leisure I will try to make a copy yourself,it can be downloaded the disk image was done with a different version of the original.

on the website http://accuraterip.com/ there are offset values in the read for many drives.
-Select your drive from the list
-open the program "Exact Audio Copy",
-select the option "drive parameters",
-select the tab "displacement and velocity",
-enter an appropriate value in the "use offset correction (offset) read",
-Click on "OK"
-Copy CD.
On the website saying that should really help.

By the way, there for Macs the program is (Rip (Apple MAC)).

Forgive me, I couldn't resist

Downloaded yesterday disc Healing(where I will not say, I think everyone knows)
The author has made the overview of the original disk(purchased from You on the website) so decided to earn this, laying on the exchanger. The contents of the disc on the screen. Made the image in Nero.

General information - MediaInfo:
Mother Nature 1 - MotherNature1.wav
Wave: 505 MB, 50 m
1 audio stream: PCM (Microsoft)
The first audio stream
1411,2 Kbit/sec, 44.1 KHz, 2 channel(s), PCM (Microsoft)

Is it possible to consult why it didn't work, and whether the disk to the original? Although it is not reasonable to ask - but all the same, because when buying things that should be full of data that we buy, so I would like to know it or not. I don't mind buying - but if there where to download, why not!!! Although I respect the work of people.

Here clamped to mp3,you can see how reduced frequency. I'm not a Pro but noticed.
By the way renaming the. wav plays mp3 everything is clear , but the size is the same as in wav !!

The original is the master disks,the second copy is factory-made,and you have N-th copy.Andrew already wrote about how and what is lost each time you copy.

Костик · Post by **Костик** » Sat Oct 10, 2009 0:40

Andrey Kabanov
Yes perhaps You are right, it is .....N copy.
But still - why am I not hooked up where is the guarantee that I will order the disk and will not have the same effect. Although I think I have a copy of the normal. It is clear that it is not correct to swing and then discuss, but as the saying goes, I think that's something are not registered. So I think it's not a big loss and guilt, that someone posted. I just don't put someone a piece of for example for verification, so for example it eliminated all the questions on how to download from other exchangers. For example I have no money - give me healing, I'll try and I'll advertise!!!

There is already talked about images, but a clear answer has not sounded - would like to doesnit: if you make from the original disk image and play it on a computer program for reading images - whether the loss of quality?
The quality of the audiocard is not considered, normal type.
Or loss of quality manifests itself during the burn?
I want to make images for the sole purpose of preservation of the material, if the original drives will die eventually.
Thanks in advance for your response specialists.

Dare to make the assumption that zhelezyachnye vosproizvodit audio CDs (factory) a little different from the audio playback CD-R or CD-RW. This refers to the DAC built into the CD drive. I shouldn't be, but figs knows that vendors build into their hardware. Distorted digital audio stream may not be different from the original, but when playing it through the DAC audio card, or audio player the sound will be different. Anyway.

First you need to accept that different devices as different DACs, and get serious tests for harmonic and non-harmonic distortion, and all sorts of other parameters. And so the sound may differ. Exactly the same as it depends on the headphones (acoustics) and amplifier.
And secondly, we can ASSUME that the correction algorithm when playing a stamping factory and recorded discs somehow different.

In this case it would be appropriate to do a test to record the sound of the original and polunochnoe copy. The sound that is played from the audio player, not directly from disk. And to compare it to. Minus the noise floor of the player (at-100dB) they are supposed to be identical.
Perhaps someone has already done similar tests with different MUSIC discs, you need a better search in the Internet.

repeat
Yes of course the author is interested in selling CDs, he doesn't care that the person is not guaranteed to be able to make a copy, but why not is not clear, because I bought the CD - you can do anything with him, and so it turns a perishable product. Friend went to Kiev and asked him to take me disc healing look)))
