| 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. |

| Overview |
| It is an audio file format which is proprietary or closed source software. It is available in four different versions. First one is the original WMA codec. This gives competition to the MP3 and it came into existence in 1999. Next is WMA Pro which is an advanced and new codec. It uses lossy compression but provides audios of high resolution. The third is WMA lossless codec and it encodes audio without losing any information. Lastly, there is WMA Voice which is again a lossy compression and it was developed for audios with low bandwidth or low bit rates. Microsoft has developed an advanced systems format which is used by ‘Windows Media Audio' to store encoded audios. Metadata objects like the album, the genre of track and title; etc. can also be added in this codec. The prime use of this extension by users is streaming on the internet. |
| Technical description |
| Microsoft has various claims about this codec. Firstly, it was alleged that at 64kbps this format will deliver the same quality of audio as of CD. This was rejected at the end. The second claim is that it gives better sound quality than MP3 at the same bit rate. Thirdly, it was professed that this extension provides a similar quality of audio at a lower bit rate than MP3 at a higher bit rate. Apart from this, there is an option available for this container i.e. DRM(Digital rights management) and this option is completely elective. One may or may not choose this choice. A number of software support this format like Windows media player, Microsoft expression encoder; etc. |
