DRM AAC and MP3
Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme for digital audio. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at many bit-rates. Apple Inc. applies FairPlay digital rights management (DRM) technology to regulate protected songs purchased from iTunes Store with iTunes. FairPlay digitally encrypts AAC audio files and prevents users from playing these files on unauthorized computers.
AAC was developed with the cooperation and contributions of companies including AT&T Bell Laboratories, Dolby, Fraunhofer IIS, Sony and Nokia, and was officially declared an international standard by the Moving Pictures Experts Group in April 1997. It is specified both as Part 7 of the MPEG-2 standard, and Part 3 of the MPEG-4 standard. As such, it can be referred to as MPEG-2 Part 7 and MPEG-4 Part 3 depending on its implementation, however it is most often referred to as MPEG-4 AAC, or AAC for short. Overall, the AAC format allows developers more flexibility to design codecs than MP3 does, and corrects many of the unfortunate design choices made in the original MPEG 1 audio specification.
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.
