MP3 (MPEG Audio Layer 3), WMA
(Windows Media Audio) and AAC
(Advanced Audio Coding) are audio com-
pression standards.
This system can play MP3/WMA/AAC files
on CD-R, CD-RW discs and USB memory.
This system can play disc recordings com-
patible with ISO 9660 level 1 and level 2
and with the Romeo and Joliet file system.
When naming an MP3/WMA/AAC file, add
an appropriate file extension (.mp3/.wma/
.m4a).
This system plays back files with .mp3/
.wma/.m4a file extensions as MP3/WMA/
AAC files respectively. To prevent noise
and playback errors, use the appropriate
file extension.
This system can play only the first session
when using multi-session compatible CDs.
MP3 files are compatible with the ID3 Tag
Ver. 1.0, Ver. 1.1, Ver. 2.2 and Ver. 2.3 for-
mats. This system cannot display disc
title, track title and artist name in other for-
mats.
WMA/AAC files can contain a WMA/AAC
tag that is used in the same way as an ID3
tag. WMA/AAC tags carry information
such as track title and artist name.
The emphasis function is available only
when playing MP3 files.
This system can play back AAC files
encoded by iTunes.
