<p>211.215.105.42: </p> <hr /> <div>Windows Media Audio ([[WMA]]) is a proprietary compressed audio file format used by Microsoft. It was initially a competitor to the [[MP3]] format, but with the introduction of Apple's [[iTunes]] Music Store, it has positioned itself as a competitor to the [[advanced audio coding]] format used by Apple. It is part of the Windows Media framework. An initial reason for the development of [[WMA]] might have been that [[MP3]] technology is patented and has to be licensed from Thomson for inclusion in the Microsoft Windows operating system.<br /> <br /> {{stub}}</div>

<p>211.215.105.42: </p> <hr /> <div>ATRAC (Adaptive TRansform Acoustic Coding) is an audio compression algorithm used to store information on Minidiscs and other Sony-branded audio players. First developed by Sony in 1991; the higher mincompression flavors of ATRAC3 and ATRAC3plus followed in 2000 and 2003, respectively. It uses quadrature mirror filters and modified discrete cosine transform to represent encoded audio.<br /> <br /> {{stub}}</div>
