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.

Ogg Vorbis (OGV) is a free, open-source, unpatented multimedia container format and codec. It is part of the Ogg family of formats and codecs, which the non-profit Xiph.Org Foundation developed to compete with patented codecs. OGV can time-division multiplex (TDM) audio, video, text (subtitles), and metadata. It supports streaming, as well as lossy and lossless compression. However, it does not support menus.

 

 

How to open an OGV file?

VLC media player is the best choice for opening OGV files. Other good choices are Winamp for on Microsoft Windows OS, and Elmedia on Mac OS X.

 

It is possible for OGV to play in Windows Media Player and DirectShow-based players, but only with the use of a DirectShow filter. On the other hand, if the player is not based on DirectShow, then the filter is not necessary.
