Playable music file formats

This unit supports music files in the formats shown below.
Type File extension
MP3 .mp3
.m4a, .aac and

About MP3 files
MP3 files can have a constant bit rate (CBR) or a variable bit rate (VBR).
Both types of files can be played on this unit, but the search and super
fast search functions are slower with VBR files. If your priority is oper-
ability, we recommend recording MP3 files in CBR.
About AAC files
! AAC is the abbreviation of "Advanced Audio Coding", a basic format
of audio compression technology used for MPEG-2 and MPEG-4.
! The file format and extension of AAC data depends on the applica-
tion used to create the data.
! On this unit, in addition to AAC files encoded with iTunes
the extension ".m4a", files with the extensions ".aac" and ".mp4" files
can also be played. However, AAC files that are copyright-protected,
such as those purchased from the iTunes Store, cannot be played.
Also, depending on the version of iTunes in which the file was
encoded, it may not be possible to play the file.
About ID3 tags
The tag information types which can be registered from a music file are
ID3 tags (v1, v1.1, v2.2.0, v2.3.0, and v2.4.0) or meta tags.
About music file artwork
The file format for artwork images that can be added to music files is
JPEG (extensions: ".jpg" or ".jpeg").
