DRM protection: what is it, how to remove it?

DRM is Digital Right Management, which translates as "digital rights management". Thus, the answer to the question: "DRM-protection - what it is" will be: "This is a class of technologies that publishers use to control content." This can be expressed in this form: an audiobook that was purchased digitally on the site will be reproduced normally on the computer with which the acquisition was made. But if you copy it to another computer, it will become an unnecessary file that can not be opened by any player.

These examples of the use of DRM technologies can be much more difficult.

DRM was designed from the outset to prevent the copying of digital products. But the next generation of technology has provided tools for limiting viewing, printing, editing.

When trying to protect the interests of copyright holders, DRM protection has caused a considerable number of complaints from users who purchase digital products. The lack of the opportunity to use the purchased music with the help of various devices negatively influenced the demand of customers. As a result, publishers realized that there is the possibility of selling music digitally without imposing DRM protection. It will be even more successful. In other words, DRM protection has even affected the sale of various digital products.

DRM protection - what is it?

These technologies eventually gained support in the legislation. For example, in a large number of countries, there are rules in the laws that prohibit circumvention of copying protection. In these states, disputes about whether DRM protection is necessary, how to remove it, etc., are already essentially illegal.

But DRM also has another complication due to the fact that such technologies can become a hindrance to users in the exercise of their legal rights. That is why, in order to understand, DRM-protection - what it is, it is necessary to realize that it is not possible to create backup copies of the purchased work.

Without deepening the legislative practice on the application of various laws in everyday life, it is possible to suggest a scheme how to remove DRM protection, which will be completely legal in most states. An exception is only Australia. It is possible to create multiple copies for your needs or for a reserve, but not for sale or distribution. It should be noted that the process of creating copies of more than 10 pieces can be regarded as commercial use. Therefore, you should avoid copying more than the norm. There are no clear limitations on the creation of copies. For this reason, it is technically possible to lose DRM somewhere in the process of receiving mp3 copies that are not protected. But using a program that is designed to disable copying protection may be a violation in terms of laws. Thus, when talking about how to circumvent DRM protection, you should remember that you can do this only for your own personal purposes.

How can this be done?

But it's good that this technology can be removed with the help of programs for general use, which are not covered by DRM-protection. How to remove it? The best example in this case is the mp3Recorder Studio application. To do this, you must enable playback of the purchased audio file with protection when using the program required for this (WMP, iTunes or other). Next, you need to make a sound capture using mp3Recorder Studio and then save audio directly to mp3. In this process, the built-in sound card function will be used, which allows you to capture sound in the middle of the device. Most sound cards have a recording device called "Stereo Mix". However, different names are used. This device allows you to capture everything that is played back by a sound card. To do this, you may need to install the latest driver from the official site of the card manufacturer. Usually, drivers that are automatically installed by Windows, most often turn off and hide such a device.

"Digital copyright management" (or, more simply, a system of copy protection) in meaning should protect copyright. But in reality it, moreover, does not perform its main function, but also makes the PC accessible to hackers. How and for what reason is this happening?

Why do I need to unprotect DRM?

DRM systems can also be unsafe. In the case of incorrect variants for the implementation of copy protection, it is possible to open holes in the computer security system, which in turn, in the absence of DRM, would remain closed. Here the matter is that to block ordinary copying functions in the OS, software rights management packages need the widest rights to access system files, and in fact they intercept the management of such functions.

A good example of unsafe implementation of this technology will serve as a protection system from the copying of audio CDs from Sony BMG. This rootkit was placed on a large number of audio CDs from a music label, which is one of the most famous in the world. When a similar disk was loaded into the computer's CD-ROM, the XCP program for WINDOWS was automatically started in the automatic mode. She had to protect herself from copying the whole album or the theft of tracks from the disc.

The XCP rootkit penetrated deep into the OS, and at the same time it was installed completely independently. The possibility of uninstallation using conventional methods was impossible. Also during the work he occupied a large part of the memory and could be the cause of failures. But the most important thing - about this rootkit and about its functioning absolutely nothing was written in the user agreement (EULA). All this despite the fact that almost no one reads such agreements.

But the most important is that the XCP rootkit created a real threat to the entire system. For example, after installing it, all files that start with $ sys $ acquired the "hidden" mode. This was immediately used by the creators of the viruses. For example, the trojan Breplibot, which was sent in attachments to E-mails, was detected only by antiviruses and programs. Users such unsafe files were absolutely not visible.

How protection is disabled

DRM-protection on the files WMV and WMA is done in stages.

Nowadays most of the downloaded audio and video files that are protected (WMP, iTunes, Rhapsody, Napster, Bearshare, Spiral Frog) are DRM-files.

The process of writing a file is not complicated. There is a free technique for removing DRM protection from WMV and WMA files. This is done in two sets.

1. You need to write the DRM WMA file to a CD or DRM WMV to a DVD.

2. It is necessary to remove WMV and WMA with protection on the PC itself, then DRM-protection will be disabled.

Overwrite method

This method is the most popular and affordable. It consists in writing DRM WMA and DRM WMV files with a regular converter that converts recorded and unprotected files. It is because this technology is easy to use that formats that differ from DRM WMA and DRM WMV will also be supported by converters such as SoundTaxi, NoteBurner and others. But even here there are disadvantages.

New technology

Hook Hook is an advanced technology by which EPUB DRM protection can be disabled. When comparing these programs with the rewriting programs, this type has a noticeably fast conversion. It will not be easy to work with some of the DRM formats, which have new high-quality encryption techniques.

After the testing, the result was obtained, that the protection of DRM WMA and DRM WMV is simply removed with the help of Digital Music Converter. This program can extract audio content from DRM WMV files. Also this program supports other unprotected formats, such as: mp3, M4b, M4A, WAV, AC3, AAC.


Conversion steps:

1. First, you need to add DRM WMA, DRM WMV, or other files that are unprotected.

2. You must select the desired outgoing format.

3. Then click on "Start" and enter the license number.

What is DRM? Why do I need to remove DRM from WMA WMV files?

Speaking about the meaning of the term "DRM-protection" (what it is - we generally considered above), you need to know: these are programs that protect against copying and complicate the actions that are associated with video and audio files. For example, if WMA or WMV files downloaded from WMP are protected with DRM, then it is possible to play them only with compatible devices. If each song was from DRM, then the user would have to purchase this track on the disc to listen to it using a player or a car stereo. For example, if you purchased tunes on iTunes and they are auditioned on the iPOd, then because they have already been purchased, the user will not need to perform this action again and again. You just need to remove it from the DRM file, and it will be possible to play it on iPod, Zune, PSP, CD player, PC and other devices.


This method is not entirely appropriate, sometimes it can even cause damage to the CD-Roma. WMP has the ability to record only DRM WMA and DRM WMV files. For other formats, you will need a DVD-Ripper.

Due to the long recording process, the conversion speed will not be better. During the recording process, it is possible to lose most of the quality of video or audio.
