What is MP3/WMA?
MP3/WMA (MPEG Audio Layer III) is a standard format for audio compression technology. By using
MP3/WMA a file can be compressed to one-tenth the size of the original.
WMA (Windows Media
TM
Audio) is format for audio compression technology. WMA files can be
compressed to a size smaller than MP3 files.
