The AMR codec, also known as Adaptive Multi-Rate audio codec, is an audio compression format developed by Ericsson. The audio format is specially optimized for speech coding. AMR speech codec consists of a multi-rate narrowband speech codec that encodes narrowband signals at variable bit rates ranging from 4.75 to 12.2 Kbit/s with toll quality speech starting at 7.4 Kbit/s, so it can provide a very outstanding speech audio performance.

So if you need to move, transfer or upload the AMR audio file from where it’s originally created, you have to firstly convert AMR to MP3 with an AMR to MP3 converter tool.
