About MP3/WMA

• Supported channel modes:
Stereo, Joint Stereo, Dual channels, Monaural

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.
