3-2. Using the audio system ● ID3 and WMA 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. ● MP3 and WMA playback When a disc containing MP3 or WMA files is inserted, all files on the disc are first checked. Once the file check is finished, the first MP3 or WMA file is played. To make the file check finish more quickly, we recommend you do not write in any files other than MP3 or WMA files or create any unnecessary folders. If the discs contain a mixture of music data and MP3 or WMA format data, only music data can be played. ● Extensions If the file extensions .mp3 and .wma are used for files other than MP3 and WMA files, they will be mistakenly recognized and played as MP3 and WMA files. This may result in large amounts of interference and damage to the speakers. ● Playback • To play MP3 files with steady sound quality, we recommend a fixed bit rate of 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 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. • When files other than MP3 or WMA files are recorded on a disc, it may take more time to recognize the disc. In some cases, playback may not be possible at all. • Microsoft, Windows, and Windows Media are the registered trademarks of Microsoft Corporation in the U.S. and other countries. 3 Interior features 223
