What is an MP3 file?

The MPEG Audio Layer III process and the resulting MP3 file are a standard technology and format for compressing a sound sequence into a very small file, while maintaining the original sound quality during replay. MP3 offers audio in CD quality and is one of the most common music file types. The sound quality varies depending on the setting such as bitrate, sample rate, joint or normal stereo. MP3pro is an extension of MP3 and is intended to compensate the loss of quality in the lower bit rate range. The name MPEG is derived from the Moving Picture Experts Group, which was founded in 1991 by the Fraunhofer Institute in Germany and has developed the MP3 process. 

What is an M4A file?
