What is MP3?
MP3, whose official name is “MPEG Audio Lay
compression standard prescribed by the ISO
International Standardization Organiza
which is a joint activity institution of the IEC.
MP3 files contain compressed audio da
is capable of compressing audio data at extr
ratios, reducing the size of music files t
one-tenth their original size. This is achiev
maintaining near CD quality. The MP3 forma
such high compression ratios by elimina
that are either inaudible t
other sounds.
What is WMA?
WMA, or “Windows Media™ Audio,” is compr
data.
WMA is similar to MP3 audio data.
What is AAC?
AAC is the abbreviation for “Advanced A
and is a basic format of audio compr
MPEG2 or MPEG4.
What is FLAC?
FLAC (Free Lossless Audio Codec) is an audio file codec
for lossless compression, developed and offered as open
source software.
Codecs with lossy compression forms, such as MP3 and
AAC, reduce part of the data to improve compression
efficiency.
However, FLAC can reconstruct compressed data to be
an identical copy of the original data by performing
lossless compression. The compression ratio of FLAC is
about 50%.
What is WAV?
WAV is a standard audio format for Windows. It is the
original format before compression. You can enjoy music
with almost the same sound quality as a CD. WAV is also
known as WAVE.
What is APE?
APE is a format called lossless compression. It can be
restored to its original quality by decoding. Mainly, it is
used in “Monkey’s Audio.”
Method for creating MP3/WMA/AAC/FLAC/WAV/APE
(USB Flash drive) files
Audio data is compressed using software with MP3/
WMA/AAC/FLAC/WAV/APE (USB Flash drive) codecs. For
details on creating MP3/WMA/AAC/FLAC/WAV/APE (USB
Flash drive) files, refer to the user’s manual for that
software.
MP3/WMA/AAC/FLAC/WAV/APE (USB Flash drive) files
that are playable on this device have the file extensions.
MP3: “mp3”
WMA: “wma”
AAC: “m4a”
FLAC: “flac”/”fla”
WAV: “wav ”
APE: “ape”
WMA is not supported for the following files, Windows
Media Audio Professional, Windows Media Audio 10 std
or Windows Media Audio 10 Pro Lossless.
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.

This device may not play back correctly depending on
sampling rates.
ID3 tags
This device supports ID3 tag. If tag data is in an MP3/
WMA/AAC/FLAC/WAV/APE file, this device can display
the title (track title), artist name, and album name ID3
tag data.
For non-supported characters, “?” is displayed.
The number of characters may be limited, or not
correctly displayed, depending on the tag information.
Playing back MP3/WMA/AAC/FLAC/WAV/APE
MP3/WMA/AAC/FLAC/WAV/APE files are prepared, then
written to a USB flash drive.
• Maximum numbers of playable files/folders
USB Flash drive: 10,000 files/folders (including Root
Folder)
• Largest playable file size: 512 MB
Playback may not be performed if a USB flash drive
exceeds the limitations described above.
If a file/folder name is long, the maximum possible
number of files may decrease.
• Both Audio and Video files are counted if their formats
are playable on this unit.
Media supported
The media that this device can play back a USB flash
drive.
Corresponding File Systems
This device supports FAT 16/32, exFAT.
The maximum nested folder depth is 8 (including the
root directory). File names are limited to 256 characters
(including the extension).
Valid characters for folder/file names are letters A-Z (all
caps), numbers 0-9, and ‘_’ (underscore).
Terminology
Bit rate
This is the “sound” compression rate specified for
encoding. The higher the bit rate, the higher the sound
quality, but also the larger the files.
