About MP3/WMA/AAC

CAUTION
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
holder is strictly prohibited by the Copyright Act and by
international treaty.
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 by using MP3/WMA/AAC specified
software. For details on creating MP3/WMA/AAC files, refer to
the user's manual for that software.
MP3/WMA/AAC file extensions that can be played back on the
unit are as follows:
MP3: "mp3"
WMA: "wma" (ver. 7.1, 8, 9 supported)
AAC: "m4a"
Depending on the software that is used to create AAC, the file
format may differ from the extension.
Unit playback of AAC files encoded by version 7.0 iTunes is
supported.
