Mp3/Wma Operations - Clarion MAX983HD Owner's Manual

MP3/WMA Operations

This system can play MP3/WMA data recorded on a disc or saved in an SD card.
About the MP3/WMA files
What is MP3/WMA?
MP3 and WMA are the audio compression
methods which have penetrated into PC users
and become a standard format.
MP3 is an audio compression method and
classified into audio layer 3 of MPEG standards.
WMA is an audio compression method
developed by Microsoft Corporation.
These features compress the original audio data
to about 10 percent of its initial size with a high
sound quality. This means that about 10 music
CDs can be recorded on a CD-R/RW disc to
allow a long listening time without having to
change CDs.
Displaying MP3/WMA Tag titles
Tag information such as title, artist and album
title can be displayed for an MP3/WMA file
containing the Tag information.
Note:
• This system does not completely support the ID3
version 2.x tag format. These tags may not be
displayed.
Precautions on the MP3/MWA data
• Files other than MP3/WMA data cannot be
played. In addition, some files may not be
played because of the encoding format. When
a file cannot be played, the next file is played
instead.
• Some noise may occur depending on the type
of encoder software used to encode the data.
• You can apply the VBR (variable bit rate)
format when encoding, but setting the value of
VBR to within ranges from 32 kbps to 320 kbps
is recommended. In case of data recorded in
VBR, the displayed play time may be slightly
different from the actual play time.
• Tag information entered with 2-byte characters
may not be displayed properly on the display.
• Files that the DRM (Digital Rights
Management) function is set cannot be played.
• Add a file extension ".MP3" or ".mp3" to an
MP3 file, and ".WMA" or ".wma" to a WMA file
using single byte characters. If you add other
file extension or forget to add the file extension,
the file cannot be played.
Precautions when preparing a disc/
SD card
● Logical format (File system)
Specify the following formats as the file system.
Otherwise, normal playback may not be possible.
For a disc:
Specify "ISO9660 level 1" or "level 2" (without
including expansion format) as the writing format
when writing MP3/WMA files on a disc.
For an SD card:
Use the SD cards formatted in FAT16 or V-FAT
format to store MP3/WMA files.
● Folder structure
• The folder hierarchy must be within 8
hierarchical levels. Otherwise, playback will be
impossible.
• You can store the MP3 files and WMA files
together in a folder.
● Number of files or folders
For a disc:
• The maximum allowable number of folders is
255 (including root directory).
• The maximum allowable number of files in a
disc is 512.
• The maximum allowable number of files in a
folder is 255.
For an SD card:
• The maximum allowable number of folders is
99 (including root directory).
• The maximum allowable number of files in a
card is 255.
• The maximum allowable number of files in a
folder is 99.
● Folder representation in the Folder list
• Only folders containing MP3/WMA files (1 to
4 in illustration) are displayed on the list.
Folders containing no MP3/WMA file are not
displayed.
• Folder hierarchy is ignored, and unified into 1
level.
• Folders are arranged in the order of the folder
creation.
