Mitsubishi Multi Communication System
MP3/WMA
CD-ROM and CD-R/RW discs with MP3/WMA format files
written on a computer can be played on the system.
There are restrictions on the type of files and media that can be
used, so read the following information carefully before writ-
ing MP3/WMA files to discs. Also be sure to carefully read the
1
user manual for your CD-R/RW drive or recording software
and use your equipment accordingly.
NOTE
Never give copies of music CDs or files to others or
upload them to an Internet server, as such behaviour is
illegal, whether for profit or not.
Do not change the file extension of any file that is not
MP3 to ".mp3" or any file that is not WMA to ".wma".
Playing discs with such files can cause system recognition
errors that result in loud noise that could damage your
speakers.
Proper playback may be impossible, depending on the
recorder and recording software used to write to the disc.
In such cases, refer to the user manual for the device or
software that was used.
Extensions are sometimes not added, depending on the
computer operating system, version, software, or settings.
In such cases, add either ".mp3" or ".wma" extensions
and then write to disc.
Unsupported MP3 and WMA files may not playback
properly, and file and folder names may not be displayed
properly.

What are MP3/WMA?
E08113500010
MP3 is an abbreviation of "MPEG-1 Audio Layer 3".
MPEG is an abbreviation of "Motion Pictures Experts Group",
which is a standard for compressing digital video data for use
in media such as video CDs.
MP3 is one of the audio compression schemes covered by the
MPEG digital audio compression standards. MP3 compression
reduces the number of bytes in a song by eliminating large
sound waves within the sound range that is imperceptible to the
human ear, producing high quality audio files with a low vol-
ume of data.
MP3 compression allows for the contents of a conventional
music CD to be reduced by a factor of about 10. This means
that the contents of 10 music CDs can be recorded on a single
CR-R or CD-RW.
WMA is an abbreviation of Windows Media Audio, which is
another audio compression standard.
WMA can be used to create and save audio files at a higher
compression rate than with MP3.
