What is WMA?
WMA is stands for Windows Media Audio, a Microsoft file format and codec for encoding digital audio files. WMA was intended to be a competitor for the MP3 and RealAudio audio formats. WMA files can be of any size compressed to match many different connection speeds, or bandwidths.

What is MP3?
MP3 stands for MPEG Audio Layer 3, which revolutionized digital music. Derived from the audio sections of the MPEG-1 and MPEG-2 video specifications, MP3 compresses CD-quality sound by a factor of roughly 10, while retaining most of the original fidelity. MP3 files are played on the computer via media player software, such as Apple's iTunes and Microsoft's Windows Media Player, as well as in countless iPods and other handheld players. While 128 Kbps (kilobits per second) is considered the norm for MP3 files, MP3s can be encoded to bit rates from 8Kbps to 320 Kbps. The higher the bit rate, the better the sound and the larger the file.
