| 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. | A MIDI file does not contain any music but instructions about music events and objects. The device interprets the commands in the MIDI file and reproduces the music-related events. The compact size of these files led to their widespread use in computers, mobile phone ringtones, webpage authoring, and musical greeting cards. |
| 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. | |
