Convert RMVB to AMR online, for free.
RealMedia Variable Bitrate (RMVB) is an extension of the RealMedia multimedia container format. It uses variable bitrate (VBR) compression, which means that it adjusts bandwidth depending how difficult or easy it is to compress a segment of the multimedia content, such as high-action versus low-action scenes.
RealPlayer supports playback of RMVB files in Windows, Mac OS X, and Linux. Since RealNetworks developed RMVB, RealPlayer is the default platform for this file type. It is available as a free download and is easy to use. It supports captions, subtitles, and streaming.
Other software that can open RMVB files include VLC media player and ALLPlayer, which are both free. Keep in mind that RMVB is proprietary and relatively uncommon; used mostly for playing files locally instead of streaming over the Internet.

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).
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.
