Originally being developed by a Third Generation Partnership Project II, it's used in the third generation mobile phones, 3g2 is basically used as an audio as well as video file format. It is a relatively similar file format to 3gp with some advancements as well as limitations. Specifically, the 3g2 format is for CDMA based mobile phones rather than GSM-based phones, this format is used in fourth generation phones as well. Basically, it is for video viewing, it is also used for transferring photos and videos through the internet. Based on the standards of MPEG-4, it is developed in the light to play the media and to deliver it through the internet connection over high speed.
The advanced audio coding audio format or AAC format for short is a standardized audio encoding format designed to succeed the popularized mp3 format. It is the result of the collaborative efforts of several companies including bell labs, Nokia, and Sony among others. It was initially released in 1997 as part of the lossy digital audio compression family of audio encoding formats. AAC enjoys a wealth of native compatibility and support by different platforms, hardware, and software applications including video game consoles such as the PlayStation 3, Nintendo DSi, and platforms such as Android, and YouTube. Today even diverse hardware such as in dash car audio players have native support for the format.

3g2 format has a contrasting similarity with MP-4 and is a more simplified version of the complex MPEG-4. It is actually designed to accommodate in the cellular phones, its bandwidth requirements are reduced in order to reduce the storage required. It stores and streams the videos and audios as done by the 3gP format. However, the audio streams that are stored by the 3g2, are in the extensions such as EVRC-B, SMV, EVRC-WB, VMR-WB, EVRC, 13k or QCELP.
The AAC supports stereo playback at a maximum and acceptably modest 96 kilobits per second. Sample frequencies can range from 8 to 96 kilo hertz, and maximum number of supported channels is 48. Resulting AAC file sizes are typically smaller in comparison with those of its closest rival format mp3.
