How to Convert MP4 to MP3 With Windows
The MP4 (or MPEG-4) multimedia file format has the capability to embed video, audio and 3D graphics in a single file to be played on the Internet or through portable media devices. Although MP4 has significantly more capability than MP2 or MP3 formats, many audio players still require that audio files be in the MP3 format in order to be played on the devices. As a result, a common task that arises for Windows users is converting audio files from MP4 to MP3 format. Several freeware options are available to help you make the conversion.
