| Description | 3GPP was developed to make a global third generation mobile phone system specification with the aim to drive file sizes down and have a format that worked across a multitude of different mobile devices. 3GPP are deployed across much of the GSM market. | MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players. |
| Technical details | The 3GPP file stores the video element as MPEG-4 Part 2/H.263/MPEG-4 Part 10 (H.264) and the audio element as AMR-NB/AMR-WB/AMR-WB+/AAC-LC/HE-AAC V1. It is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for 3G UMTS multimedia services. It is used primarily on 3G mobile phones but can also be played on some 2G and 4G phones. | The use of lossy compression is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio. An MP3 file that is created using the setting of 128 kbit/s will result in a file that is about 1/11 the size of the CD file created from the original audio source. |
