How to Convert WMA to MP4

Windows Media Audio or as it is also known WMA is an audio data compression technology created by Microsoft. The name may also be used to refer to its audio file format or its audio codecs. It is a proprietary technology that makes up part of the Windows Media framework. WMA is comprised of four distinct codecs.

The original WMA codec, which is known simply as WMA, was formulated as a competitor to the popular MP3 and RealAudio codecs. WMA Pro, which is a newer and more advanced codec, supports multichannel and high resolution audio. A lossless codec, WMA Lossless, compresses audio data without loss of audio quality. Lastly WMA Voice, which targets voice content, utilizes compression using a range of low bit rates.

MPEG-4 or MP4 file format, or as it is formally known ISO/IEC 14496-14:2003, is a multimedia container format standard specified as a part of MPEG-4. It is typically used to store digital video and digital audio streams, specifically for those defined by MPEG. It can also be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 allows video streaming via the Internet.

Since MP4 is compatible with many forms of players, conversion from WMA may have to be performed. To do this you will need to get the appropriate conversion software.
