3GPP2 (3G2) is a multimedia container format designed for third generation (3G) code division multiple access (CDMA2000) networks. Since CDMA is a technology for mobile, the 3G2 format allows mobile phones on CDMA networks to capture, save, deliver, and play media over high-speed wireless connections.

 

How to open a 3G2 file?

The best application for opening 3G2 is Apple QuickTime. And although 3G2 is designed for mobile, the file format opens easily on most operating systems, including Linux, Mac, and Windows.

 

3G2 is a flexible file format that supports captions and subtitles via Timed Text. It does not support interactive menus, but it is compatible with free third-party tools that provide such support. One example is AutoGK.

Adaptive Multi-Rate (AMR) is a compressed audio file that is often used for speech coding. The AMR speech codec focuses on narrowband signals, which makes it ideal for voice recordings and radio. It is used regularly in Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS).

 

How to open an AMR file?

Since AMR files are often used on mobile phones, including for MMS messaging, most 3G mobile devices are able to open them. AMR also opens with VLC media player, QuickTime, RealPlayer, and Xine.

 

Other software, such as the free audio-editing software Audacity, can open AMR files. Download audacity easily at SourceForge.net. Because AMR files are heavily compressed and focused on narrowband signals, they are not suitable for music files.
