MP3 Technical Specifications

File extension	.mp3
File category	Audio
Stands for	MPEG Audio Layer-3
Developer	Fraunhofer- Gesellschaft (A German research institute)
Overview	It is a digital Audio which compresses the tracks using the lossy format. Although, it follows the lossy format, yet, there will be no noticeable change in the quality of audio. It only discards the superfluous information that a human ear is inefficient to process or hear. With the help of the this extension, one can upload and download audio files with ease, irrespective of the internet connection speed even a dial-up connection users can access these files. There are a number of MP3 Blogs(music blogs) available on the internet where maker uploads music files and a user can download the same without any trouble. These blogs help people to get an insight into the music world. Hype Machine is an example of an audio blog.
Technical description	MP3 uses lossy data compression, which means when data is encoded it is not the full original version, it’s a substitute to original copy but in a smaller size. This compression can lead to a decrease in file size, ranging from 75% to 95%. This format is based on perceptual coding due to which this extension screens out the noise, and results in an audio file that uses a low bit rate(lowest bit rate in it is 128kbps). It provides audio of fair sound quality. As it is only an audio file, thereby, if there are any images linked to it then they need to be stored in a separate file.

3G2 Technical Specifications

File extension	.3g2
File category	Video
Stands for	3GPP2 (An extended form of MPEG-4 Part 12)
Developer	3rd Generation Partnership Project 2
Overview	The 3G2 format is an upgraded version of .3GP file and it functions to save both audio and video files in 3G phones which are based on CDMA (Code Division multiple access). By using this format, we can transfer files over the internet and can store videos on mobile phones. It consumes less storage space when compared to the 3GP file. Therefore, it helps to save the disk space. Also, this format is very good for mobile streaming and downloading as it supports bandwidth, which is easily compatible with 3G cell phones. Moreover, this is both ISO Base media file format MPEG-4 Part 12 and MP4 file format MPEG-4 Part 14. We can use various software to open these files. For example, Apple’s free QuickTime, VLC Media player; etc.
Technical description	It is a parallel format of MPEG-4 Part 14 or MP4 but a simplified version, not the complex one. This is the perfect format for 3G cell phones to store videos as low bandwidth is required and besides this, it takes less space to store videos. 3GPP2 can store similar video and audio streams as of 3GP and some additional streams as well. For instance- AMR-NB, AMR-WB, AMR-WB+, AAC-LC, HE-AAC v1, and HE-AAC v2. In addition to these aforesaid streams, EVR-C, EVRC-B, EVRC-WB, VMR-WB are other extra streams used in this format. MPEG-4 media is stored in 3G2 format using MP4 and AVC file format specifications.
