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 AAC?
AAC is the abbreviation for “Advanced Audio Coding,” and is a
basic format of audio compression used by MPEG2 or MPEG4.
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.
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: “mp3”
WMA: “wma” (ver. 7.1, 8 and 9 are supported)
AAC: “m4a”
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 version 7.0 or earlier is
supported.
Supported playback sampling rates and bit rates

This device may not play back correctly depending on sampling

Except for private use, duplicating audio data (including MP3/
WMA/AAC data) or distributing, transferring, or copying it,
whether for free or for a fee, without permission of the copyright
