MP3/WMA File
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
Root folder
The root folder is found at the top of the file system. The root folder
contains all folders and files.
