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).
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.

WebM (WEBM) is a freely-licensed file container designed for the Web. Specifically, it was designed to be compatible with HTML5, originally. It supports chapters, captions, subtitles, metadata tags, streaming, attachments, 3D codecs, 3D containers, and hardware players. WEBM compresses video streams with VP8 or VP9 codecs, and audio with Vorbis or Opus codecs.
VLC media player and MPlayer can open WEBM files on any operating system (OS). Other good choices for opening WEBM include Winamp for Microsoft Windows OS, and Elmedia for Mac OS X.
Microsoft browsers do not have built-in WebM codecs. Therefore, install the codecs separately. However, most browsers support WEBM files.
