About MP3/WMA/AAC
What is MP3?
MP3, whose official name is “MPEG-1 Audio Layer 3,” is
a compression standard prescribed by the ISO, the
International Standardization Organization and MPEG
which is a joint activity institution of the IEC.
MP3 files contain compressed audio data. MP3
encoding is capable of compressing audio data at
extremely high ratios, reducing the size of music files to
as much as one-tenth their original size. This is achieved
while still maintaining near CD quality. The MP3 format
realizes such high compression ratios by eliminating the
sounds that are either inaudible to the human ear or
masked by other sounds.
What is WMA?
WMA, or “Windows Media™ Audio,” is compressed
audio data.
WMA is similar to MP3 audio data and can achieve CD
quality sound with small file sizes.
What is AAC?
AAC is the abbreviation for “Advanced Audio Coding,”
and is a basic format of audio compression used by
MPEG2 or MPEG4.
Method for creating MP3/WMA/AAC files
Audio data is compressed using software with MP3/
WMA/AAC codecs. For details on creating MP3/WMA/
AAC files, refer to the user’s manual for that software.
MP3/WMA/AAC files that are playable on this device
have the file extensions “mp3” / “wma” / “m4a”. Files with
no extension cannot be played back (WMA ver. 7.1, 8
and 9 are supported). Protected files are not supported,
neither are raw AAC files (using the “.aac” extension).
There are many different versions of the AAC format.
Confirm that the software being used conforms to the
acceptable formats listed above. It’s possible that the
format may be unplayable even though the extension is
valid.
Playback of AAC files encoded by iTunes is supported.

characters, “NO SUPPORT” is displayed.
If information contains characters other than ID3 tag
information, the audio file may not be played back.
The tag information may not be correctly displayed,
depending on the contents.
CAUTION
Except for private use, duplicating audio data
(including MP3/WMA/AAC data) or distributing,
