The conversion of the file AMR to AAC will allow you to edit a file using other software than before. The conversion AMR to AAC is particularly helpful in cases where you want to give certain features to the data in the AMR file, and all the programs that support the AMR format do not have the possibility to introduce the desired changes.
Just download one of the programs from the list and install it on your computer. After starting the program, select AMR file that you want to convert. Then select the target format (in this case AAC) and follow the instructions. Save the converted AAC file in the selected location. From this moment you can open the AAC file with all the programs that you will find here.
