How to Convert MP3 to M4A

MPEG-4 Part 14 or MP4 file format is a multimedia container format standard which comprises part of MPEG-4. It is widely used to store digital video and digital audio streams, primarily those defined by MPEG, but may also be used to store other forms of data inclusive of subtitles and still images. Seeing as the two different file extensions used for naming audio-only MP4 files there has been some amount of problems for both users and multimedia playback software. Since MPEG-4 Part 14 is a container format, MPEG-4 files have the potential to contain any number of audio, video, and even subtitle streams, making it impossible to identify the type of streams in an MPEG-4 file based on its filename extension alone. In response to this issue, Apple Inc. began using and popularizing the .m4a file extension. Software capable of audio/video playback are now generally able to recognize files with either .m4a or .mp4 file extensions as there are no longer file format discrepancies between the two. Most software capable of creating MPEG-4 audio will enable the user to choose the filename extension of the MPEG-4 files that have been produced.
MPEG-1 Audio Layer 3 or as it widely referred to as MP3, is a patented digital audio encoding format that utilizes a form of lossy data compression.
A person may opt to convert from MP3 to M4A if issues of compatibility arise. Also the quality of M4A is better and file sizes are generally smaller than MP3 files. Another advantage of M4A is that unlike MP3, no licenses or payments are needed for a user to stream or distribute content in M4A format. To convert from M4A to MP3 you may use any specialized multimedia software that has this option.
