Notes on creating MP3 discs

•When converting audio data to MP3

To enjoy high sound quality, create MP3 files with a sampling frequency of 44.1 kHz and a fixed bit rate of

128kbps.

•When creating MP3 discs

Do not store more than 127 albums in a disc. Also, keep the total number of albums and tracks 300 or less in a disc.

•To play tracks in the order they were recorded

1.Use a writing software capable of recording MP3 tracks (files) in numerical and alphabetical order. For details on using the software, refer to the operating instructions

supplied with the software.

2. Use only one album. (Do not create a sub-album within En an album.)

3.Include a two or three-digit number at the beginning of each album or track name so that the albums and

tracks are played in order. <example of recommended names>

01XXXXX.mp3

02XXXXX.mp3

03XXXXX.mp3

04XXXXX.mp3

05XXXXX.mp3

<example of names not recommended> 1XXXXX.mp3 5XXXXX.mp3 10XXXXX.mp3 15XXXXX.mp3 20XXXXX.mp3

(Numbers at the beginning have different digit number. The tracks will not be played in this order but played in the order of “1”, “10”, “15”, “20” and “5”.)
