Bit rate
It is the “sound” compression ratio defined for encoding. The higher the bit rate, the higher the sound quality
but also, the larger the file.
Sampling frequency
This value indicates the number of times of data sampling (recording) per second. For example, a sampling
frequency of 44.1 kHz is used for music CD; therefore, the sound is sampled (recorded) 44,100 times per
second. The higher the sampling frequency, the higher the sound quality but also, the larger the data size.
Encoding
Converse music CD, WAVE (AIFF) files and other audio files into specified audio compression format.
Tagging
Write in the song information of the MP3/WMA/AAC/M4A/WAV/FLAC/APE/DSD file; for example, song
title, album, file format, artist, data, and file size.
Root folder
The root folder (or root directory) can be found at the top of the file system. The root folder includes all
folders and files.
