DRM WMA and MP3
WMA consists of four distinct codecs. The original WMA codec, known simply as WMA, was conceived as a competitor to the popular MP3 and RealAudio codecs. Apart from Windows Media Player, the WMA format can be played using MPlayer, RealPlayer, Winamp (with certain limitations—DSP plugin support and DirectSound output is disabled using the default WMA plugin), and many other software media players. The Microsoft Zune media management software supports most WMA codecs, but uses a variation of Windows Media DRM which is used by PlaysForSure.
Like AAC and Ogg Vorbis, WMA was intended to address perceived deficiencies in the MP3 standard. Given their common design goals, it's not surprising that the three formats ended up making similar design choices. All three are pure transform codecs. Furthermore the MDCT implementation used in WMA is essentially a superset of those used in Ogg and AAC such that WMA iMDCT and windowing routines can be used to decode AAC and Ogg Vorbis almost unmodified.
MP3's use of a lossy compression algorithm is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners, but is not considered high fidelity audio by most audiophiles.
An MP3 file that is created using the mid-range bitrate setting of 128 kbit/s will result in a file that is typically about 1/10th the size of the CD file created from the original audio source. An MP3 file can also be constructed at higher or lower bitrates, with higher or lower resulting quality. The compression works by reducing accuracy of certain parts of sound that are deemed beyond the auditory resolution ability of most people.

Microsoft initially claimed that WMA delivers the same quality of MP3 at half the bit rate;[11] Microsoft also claimed that WMA delivers "CD-quality" audio at 64 kbit/s. The former claim however was rejected by some audiophiles according to EDN. RealNetworks also challenged Microsoft's claims regarding WMA's superior audio quality compared to RealAudio
Microsoft first announced its plans to license WMA technology to third-parties in 1999. Although earlier versions of Windows Media Player played WMA files, support for WMA file creation was not added until the seventh version. In 2003, Microsoft released new audio codecs which were not compatible with the original WMA codec.
NoteBurner Protected WMA to MP3 Audio Converter is well known for its magic fast converting speed and its capability of converting DRM WMA protected audio files to MP3, WMA and WAV, especially convert M4P to MP3.
Youc can now free download NoteBurner Audio Converter to convert DRM protected music to MP3, DRM protected WMA to MP3, M4P to MP3, or M4B to MP3. With the program, you can also convert all types of DRM-free audio files to MP3, WMA and WAV at fast speed.
Since NoteBurner DRM Protected WMA to MP3 Audio Converter uses virtual burning technology, media player like iTunes, Windows Media Player or Real Player, or audio editing program like Adobe Audition, is required to co-work with the program to complete the converting.
NoteBurner DRM Converter is a program that can be used to convert DRM protected WMA to MP3, DRM protected M4P to MP3, DRM protected M4B to MP3, as well all types of DRM-free audio files to MP3, WMA and WAV formats. It operates a little differently than the other products we reviewed because it is a virtual CD burner. It must be used in conjunction with a media player that can burn CDs because it makes the media player “burn” the song as a file on the hard drive instead of onto a real CD.
