(Windows Media Audio) Developed by Microsoft, WMA is one of
today's most pervasive Internet audio formats. Though not as popular as MP3,
proponents of lossy WMA claim that it can outperform MP3 in the area of sound
quality, particularly with files encoded at lower bitrates such as 64 or 96
Kbps. This performance advantage makes it handy for applications such as
portable digital audio players, where total play time is limited by a finite
amount of internal memory.
(Windows Media Video) This is Microsoft's proprietary lossy compression format
for motion video. WMV is used for both streaming and downloading content via the
Internet. Microsoft's Windows Media Player is usually bundled with the most
recent version of Windows, and it allows playback of many audio and video file
types, including WMA and WMV.
