How to: Convert M4A to MP3

MPEG-4 Part 14 or as it is more often refered to, MP4 file format is a multimedia container format standard which constitutes part of MPEG-4. It is widely used to store digital video and digital audio streams, chiefly those defined by MPEG, but may also be used to store other kinds of data including subtitles and still images. Because of the two different file extensions used for naming audio-only MP4 files there has been some amount of challenges for both users and multimedia playback software. Since MPEG-4 Part 14 is a container format, MPEG-4 files have the capability to house any number of audio, video, and even subtitle streams, making it impossible to pinpoint the type of streams in an MPEG-4 file based solely on its filename extension. In response to this predicament, Apple Inc. started using and popularizing the .m4a file extension. Software that have the ability to playback audio/video are now, for usually, able to recognize files with either .m4a or .mp4 file extensions as there are no file format inconsistencies between the two. Most software capable of creating MPEG-4 audio will give the user the option to choose the filename extension of the MPEG-4 files that have been produced.
