Audio format refers to the method used to import audio data from the Internet 

or audio CDs to a computer, and then save it as an audio file.

Common formats include MP3 and WMA, etc.
MP3: MP3 (MPEG-1 Audio Layer3) is a common audio compression 

technology developed by the MPEG working group of the ISO (International 

Organization for Standardization).

MP3 can compress audio files to about 1/10 the size of standard CD audio files.
WMA: WMA (Windows Media Audio) is a common audio compression 

technology developed by Microsoft Corporation. The WMA format produces 

the same sound quality as that of the MP3 format with a smaller file size.
AAC: AAC (Advanced Audio Coding) is a common audio compression 

technology developed by the MPEG working group of the ISO (International 

Organization for Standardization). The AAC format produces the same sound 

quality as that of the MP3 format, with a smaller file size.
Linear PCM: Linear PCM is an audio recording format without digital 

compression. You can achieve the same quality as CD music by recording with 

this format.

Certain music files or video files, etc., that you purchase from a music 

download service site, etc., may apply access control technologies, such as 

encryption, to limit usage and duplication of material, in accordance with 

copyright laws.

Bit rate refers to the amount of data used to store each second of audio, 

expressed in kbps (kilo bits per second), such as 64 kbps. Generally, higher bit 

rates provide better sound quality, but require more storage space for the same 

length of audio.
