MP3 / WMA
- MP3 is short for MPEG Audio Layer 3 and refers to an audio compression technology standard.
- This product allows playback of MP3 files on CD-ROM, CD-R or CD-RW discs.
- The unit can read MP3 files written in the format compliant with ISO 9660. However it does not
support the MP3 data written by the method of packet write
- The unit can not read an MP3 file that has a file extension other than “.mp3”
- If you play a non- MP3 file that has the “.mp3” extension, you may hear some noise.
- In this manual, we refer to what are called “MP3 file” and “folder” in PC terminology as “ track “
and “ album “, respectively.
- Maximum number of directory level is 8, including the root directory. Maximum number of files
and folders per disc is 256.
- The unit may not play tracks in the order of Track numbers.
- The unit plays only the audio tracks if a disc contains both audio tracks and MP3 files.
- When playing a disc of8 kbps or “VBR”, the elapsed playing time in the display window will not
be correct and also the intro play may not function properly. “ VBR “:Variable Bit Rate.
- The unit supports the playback of WMA files. The playback of ID3 tags for WMA format is not
guaranteed, it depends on versions and availability of Cyrillic alphabet.
- WMA(Windows Media Audio) -music data compression format, created by Microsoft Corporation.
This format uses coding algorithm for compression of initial audio-record, greatly decreasing the
file size, but, saving the good sound quality even when the bit rate is low (for example, 64 Kbit/s).
- Remember that the unit may not play the tracks in order they are written on disc
Notes on creating your own CD-R or CD-RW containing MP3 files:
- To enjoy high quality sound, we recommend converting to MP3 files with a sampling frequency of
44.1 kHz and a fixed bit rate of 128 kbps. DO NOT store more than 256 MP3 files per disc.
~ For ISO 9660 - compliant format, the maximum allowable depth of nested folders is 8, including
the root directory (folder).
- When CD-R disc is used, playback is possible only for discs, which have been finalized.
- Make sure that when MP3 CD-R or CD-RW is burned that it is formatted as a data disc and NOT
as an audio disc.
- You should not write non-MP3 files or unneeded folders along with MP3 files on the disc other-
wise it takes a long time until the unit starts to play MP3 files.
- With some CD-R or CD-RW media, data may not be properly written depending on its manufac-
turing quality. In this case, data may not be reproduced correctly. High quality CD-R or CD-RW
disc is recommended.
- Up to 16 characters are displayed for the name of an Album or a Track. lD3TAG version 1.x is
required.
- Note that the unit may not play Tracks in the order that you wrote them to the disc.
