Its full name is MPEG-1 Audio Layer III or MPEG-2 Audio Layer III. People commonly use MP3 as a file format to contain a MPEG-1 Audio, or MPEG-2 Audio encoded data. And MP3 is used most widely to store audio format.
Technical Details MPEG-4 files with video and audio usually use .mp4 extension. And most data can be embedded in MP4 files via private streams. A single hint track is used to contain flow information in the file. There are many registered codecs for MP4, but only some of these are widely supported. MP3 frames containing a header and a data block make up an MP3 file. And using an MP3 data stream to perform audio encoding is lossy.
