AAC Technical Specifications

File extension.aac
File categoryAudio
Stands forAdvanced Audio Coding
DeveloperBell Labs, Fraunhofer IIS, Dolby Laboratories, LG Electronics, Sony Corporation (Combined Efforts)
OverviewAAC is the descendant of the MP3 format. It provides better sound quality using a similar bit rate as of MP3. Besides this, it uses lossy data compression but it has high standards of audio quality than of MP3. We can find this format on a number of platforms and Apple's iTunes is one such example that uses it as default audio format. Size of its file is much smaller which is approximately one-tenth of MP3 file. It also neglects the redundant information that is not even processed by the human ear and is often not noticed. Although, this format was introduced as MPEG-2 Part-7, yet, standardization was done by ISO/IEC as a part of the MPEG-2 and MPEG-4 families. It is also termed as MPEG-2 NBC (Non- Backward Compatible) because it is incompatible with MPEG-1 audio formats i.e. MP1, MP2, MP3.
Technical descriptionModified discrete cosine transform(MDCT) algorithm is used by AAC which ensures that it provides high compression efficiency. MPEG-2 PART-7 has three default profiles namely Low Complexity (LC), Main Profile (Main) and Scalable Sample Rate (SSR). These profiles come with Perceptual Noise Substitution which enhances coding efficiency and provides excellent audio quality. Furthermore, it uses Auditory Masking to ignore the surplus information. This codec has come up with advanced features which are not available in the predecessor. These include additional sample rates ranging from 8 to 96 kHz, 48 Channels, better efficiency with a simpler filter bank, higher coding efficiency for stationary signals and higher coding accuracy for transient signals.

3G2 Technical Specifications

File extension.3g2
File categoryVideo
Stands for3GPP2 (An extended form of MPEG-4 Part 12)
Developer3rd Generation Partnership Project 2
OverviewThe 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 descriptionIt 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.
