DRM-protected Audio Conversion Technology

DRM copy-protection is widely imbedded by hardware and software developers, publishers, copyright holders and individuals to smother media piracy by controlling the unauthorized usage of their digital media. DRM question still remains very controversial. Proponents dispute that DRM was pointed to suppress digital piracy, while their opponents argue that it's just a perfect marketing course in deed. Their point of view is essentially that copyright holders are disturbing the rights of legal, paid consumers is ways not covered by existing laws.

Basically, the copy-protected audio and video files are encrypted and have very limited playback, copying and burning capabilities. Every playing device, for example portable digital audio player, mobile phone or PC, should be individually licensed and authorized by special DRM online service. Nowadays Digital Rights Management code is still being widely implemented by media stores like Rhapsody, Napster, iTunes, CinemaNow, Nokia Music and many others.

There are different converting techniques used by various music and movie selling services. As all you can hear or see can be technically re-recorded, protected audio and video converting applications provide the way to reproduce and make the unprotected copy of your DRM files. The conversion process is usually automated and the output result is nearly lossless. I can mention at least three most spread conversion technologies: "analog loop", "virtual sound device" and "virtual burning" method. The predecessor of modern conversion methods was the technology for creating digital media files from analog sources, so called "audio loop". The output quality very much depended there on playback methods used. The software based on "audio loop" converting method usually requires the special cord to connect line-in and line-out. In the nature of things this technology has become outdated and was replaced by "virtual soundcard" technique, the most lossless one.
