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 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.
Tag
Song information such as track titles, artist names, album names,
etc., written into MP3/WMA files.
MP3: ID3 tag
WMA: WMA tag

writes them. Therefore, the playing order may not be the same
as the order you input. The playback order of the folders and
files is as follows. However, the folder and file playback order
differs from the folder and file number indicated on the
display.
