I made it to easily convert to MP3 those AMR sound files I record with my cellphone.
Remember, if you want to listen AMR files in Windows you just have to install "K-Lite Codec Pack" Full version, and tick the option in the installer.
- To install: double-click the program, this will register the context menu item that triggers the conversion.
- To use: go to the .amr file you want to convert to MP3 open the context menu and select "Convert to MP3"
- Download it here:
