Order of tracks
Track playback is based on the pathname order used for

disk, playback starts from Folder No. 1.
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.
