MP3s are much more compatible with other programs than AMRs.
The AMR or Adaptive Multi-Rate Codec extension is an audio format developed by the Sony Ericsson corporation (fileinfo.com). AMR files are audio recordings created on cell phones, including Sony Ericsson's models. While some programs, such as Apple's QuickTime and RealNetworks' RealPlayer, can interpret the files, most other programs cannot, leaving conversion as your only option. When running Apple's OS X operating system, converting your AMRs into MP3s is a great method for increasing compatibility.
