What is an AMR (Adaptive Multi-Rate Codec) file?

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.
