Encoders and writing software
settings
When encoding MP3 files, we
recommend that you use constant bit
rate encoding, at a compression rate of
128 Kbps, and a sampling rate of 44.1
kHz.
Note on saving files to media
When you insert a disc or “Memory
Stick” into the drive, it searches for all
the files on the media. The more folders
or non-music files on the media, the
slower playback starts (or continues).
Therefore, we recommend not to create
unnecessary folders or save non-music
files on media that you want to use with
the drive.
Playlist files
A playlist is a file on a disc or “Memory
Stick” that determines the playback
order of specific music files on the
media. You can create playlists with
basic tools such as text editors. Simply
create a file with an m3u extension,
where you specify the music file paths
(their locations on the media and
names), then write it to a disc or save it
on a “Memory Stick” containing the
music files.
Note
The drive only recognizes the following path
delimiters: “\”, “/”, and “¥”.
Examples of playlists
• Complete paths
The path is specified from the root of
the media to the file location.
\Music\Popular\New\01new.mp3
\Music\Popular\New\May\may01.mp3
• Relative paths
The path is specified from the folder
where the playlist is saved.
\New\01new.mp3
New/May/may01.mp3
MP3 file ID3 tags
The ID3 tag is basically text
information appended to MP3 files.
This text information consists of album
titles, artist names, song titles, etc.
Note
The drive supports ID3 tag format version 1.0,
1.1, 2.2
1) , or 2.3 1) . If you use any other version,
the text information does not appear properly on
the remote control display.
1) Version 2.2 unsynchronized, compressed, or
encrypted frames are not supported.
