MP3 (MPEG Audio Layer 3) is a standard format for audio compression. By using MP3, a file
can be compressed to about 1/10 of the original size.
WMA (Windows Media Audio) is Microsoft's audio compression technology. WMA files can be
compressed to a size even smaller than MP3 files.
This unit only supports certain MP3/WMA file standards, recorded media and formats. Take
note of the following when writing MP3/WMA files onto a disc.
