Table of Contents Menu Index 89 Useful Facts What are Format and Bit Rate? What is audio format? 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 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. What is bit rate? 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. What is the relationship between bit rate, sound quality, and storage size? 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. Note 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.
