MP3 files are prepared, then written to a CD-R or CD-RW using CD-R writing software. Each disc can hold up to 255 files/folders (including Root Folders).

•Media supported

•Order of tracks

Track playback is based on the pathname order used for the files when they were written to the CD.

•When CD audio and MP3 files are both present on a disk, playback starts from Folder No. 2. Also, the track display for CD audio data playback is the track numbers recorded on the disc.

Terminology

Bit rate

This is the "sound" compression rate specified for encoding. The higher the bit rate, the higher the sound quality, but also the larger the files.

Sampling rate

This value shows how many times per second the data is sampled (recorded). For example, music CDs use a sampling rate of 44.1 kHz, so the sound level is sampled (recorded) 44,100 times per second. The higher the sampling rate, the higher the sound quality, but also the larger the volume of data.

Encoding

Converting music CDs, WAVE (AIFF) files, and other sound files into the specified audio compression format.

ID3 tag

Song information such as track titles, artist names, album names, etc., written into MP3 files.
