Advantages and disadvantages of using MP3 files. |

Ensuring high quality MP3 files. |
When an MP3 file is created, it is
important to select a higher bit rate as much as possible to minimise the loss of music data. (A transfer bit rate of at
least 192kbps or higher is recommended.)In order to accommodate a wider playback compatibility, most music software like
i-Tunes and Window Media Player comes with a MP3 file creation CD ripping function. But the initial setting for creating
music file of these softwares is AAC or WMA. Please make sure to select MP3 and higher bit rate.
