MP3/WMA overview
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 of 8 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.
