those with the extension .mp3, .wma or .m4a.

discs that contain MP3, WMA and AAC files. However, only the first session
can be played.

COROLLA_TMMMS_TMMC_U (OM02494U)●ID3, WMA and AAC tags
ID3 tags can be added to MP3 files, making it possible to record the track
title, artist name, etc.
The system is compatible with ID3 Ver. 1.0, 1.1, and Ver. 2.2, 2.3 ID3 tags.
(The number of characters is based on ID3 Ver. 1.0 and 1.1.)
WMA tags can be added to WMA files, making it possible to record the
track title and artist name in the same way as with ID3 tags.
AAC tags can be added to AAC files, making it possible to record the track
title and artist name in the same way as with ID3 tags.
●MP3, WMA and AAC playback
When a disc containing MP3, WMA or AAC files is inserted, all files on the
disc are first checked. Once the file check is finished, the first MP3, WMA or
AAC file is played. To make the file check finish more quickly, we recom-
mend you do not write any files to the disc other than MP3, WMA or AAC
files or create any unnecessary folders.
Discs that contain a mixture of music data and MP3, WMA or AAC format
data cannot be played.
●Extensions
If the file extensions .mp3, .wma and .m4a are used for files other than
MP3, WMA and AAC files, they may be mistakenly recognized and played
as MP3, WMA and AAC files. This may result in large amounts of interfer-
ence and damage to the speakers.
●Playback
• To play MP3 files with steady sound quality, we recommend a fixed bit
rate of at least 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be possible in some instances,
depending on the characteristics of the disc.
• There is a wide variety of freeware and other encoding software for MP3,
WMA and AAC files on the market, and depending on the status of the
encoding and the file format, poor sound quality or noise at the start of
playback may result. In some cases, playback may not be possible at all.
• When files other than MP3, WMA or AAC files are recorded on a disc, it
may take more time to recognize the disc and in some cases, playback
may not be possible at all.

of Microsoft Corporation in the U.S.A. and other countries.
