What is MP3?
MP3 is an audio compression method and clas-
sified into audio layer 3 of MPEG standards. This
audio compression method has penetrated into
PC users and become a standard format. This
MP3 features the original audio data compres-
sion to about 10 percent of its initial size with a
high sound quality. This means that several mu-
sic CDs can be recorded on a USB memory de-
vice to allow a long listening time ∗ .
∗ Depends on the USB memory device storage
capacity.
What is WMA?
WMA is the abbreviation of Windows Media Au-
dio, an audio file format developed by Microsoft

WMA/AAC file
Usable sampling rates and bit rates
See "USB" ( page 35 ) for details.
File extensions
1. Always add a file extension ".MP3", ".WMA"
or ".M4A" to MP3, WMA or AAC file by using
single byte letters. If you add a file extension
other than specified or forget to add the file
extension, the file cannot be played.
2. Files without MP3/WMA/AAC data will not play.
The indication "NO FILE" appears in the play
time display if you attempt to play files without
MP3/WMA/AAC data.
∗ When VBR files are played, the play time display
may differ the play location.
∗ When MP3/WMA/AAC files are played, a little
no sound part is caused between tunes.
Logical format ( File system )
1. When writing MP3/WMA/AAC file, please
select "FAT12", "FAT16" or "FAT32" as the
file system format. Normal play may not be
possible if the files are recorded on another
format.
2. The folder name and file name can be dis-
played as the title during MP3/WMA/AAC
play but the title must be within 64 single byte
alphabetical letters and numerals ( including an
extension ) .
3. Do not affix a name to a file inside a folder
having the same name.
Note:
File names with less than 8 characters (not includ-
ing file extension) will be displayed in capital let-
ters.
