3-2. Using the audio system
MP3 and WMA playback
●
• When a device containing MP3 or WMA files is connected, all files in the
USB memory are checked. Once the file check is finished, the first MP3 or
WMA file is played. To make the file check finish more quickly, we recom-
mend that you do not include any files other than MP3 or WMA files or cre-
ate any unnecessary folders.
• When the USB memory is connected and the audio source is changed to
USB memory mode, the USB memory will start playing the first file in the first
folder. If the same device is removed and reinserted (and the contents have
not been changed), the USB memory will resume play from the same point in
which it was last used.
Extensions
●
If the file extensions .mp3 and .wma are used for files other than MP3 and WMA
files, they will be skipped (not played).
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.
• There is a wide variety of freeware and other encoding software for MP3 and
WMA 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.
