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/AAC/FLAC/
WAV (USB flash drive) files.

The root folder (or root directory) is found at the top of
