Audio format refers to the method used when importing audio data from the 

Internet or audio CDs to a computer and saving 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 listen to the sound with the same quality as CD music by 

recording with this format.

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

Generally, higher bit rates provide better sound quality, but require more storage 

space for the same length of audio.

Generally, higher bit rates provide better sound quality, but require more storage 

space for the same length of audio, so you can store fewer songs on the player.

Lower bit rates enable you to store more songs, but at a lower sound quality.

 If you import a song from a CD to your computer at a low bit rate, you cannot improve 

the song’s sound quality by selecting a high bit rate when transferring the song from the 

computer to the player.
