Notes on MP3 and 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 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.
