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.

Audio Video Interleave (AVI) is a multimedia container developed by Microsoft. AVI is a descendant of the Resource Interchange File Format (RIFF). With the assistance of third-party programs, AVI can support chapters, captions, subtitles, menus, streaming, attachments, and 3D containers.

 

How to open an AVI file?

Microsoft provides a downloadable and free AVI Viewer. Another way to view an AVI file is to use a version of Microsoft Windows Media Player that is compatible with the operating system.

 

While AVI files are optimized for the Internet, hardware players support them as well. If an AVI file does not open, then use VLC media player.
