|🔸 Description||MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio that uses lossy data compression. It is a common audio format for consumer audio streaming or storage and a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players.||MPEG-4 Part 14 or MP4 is a digital multimedia format most commonly used to store video and audio and store other data such as subtitles and still images. Like most modern container formats, it allows streaming over the Internet.|
|🔸 Technical details||Lossy compression is designed to reduce significantly the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio. For example, an MP3 file created using the setting of 128 kbit/s will result in a file about 1/11 the size of the CD file created from the original audio source.||Most kinds of data can be embedded in MPEG-4 Part 14 files through private streams. A separate hint track is used to include streaming information in the file.|
