FreeStar Free AMR MP3 Converter is a program for re-encoding AMR files into MP3 format. AMR is a low-quality speech audio format widely used in mobile phones, whose advantage is the very small size of files it produces. This tool allows you to convert those files into high-quality MP3 files, though you will not be able to enhance a file whose quality is already poor.
This application will allow you to select any number of AMR files and batch-convert them. The program includes four presets for file conversion: High, Optimal, Standard, and Economy quality. You will have to choose one of those presets, since the "Advanced Options" tab does not allow you to change any of the parameters (though it will show you the audio quality, the sample rate, the channels, and the audio codec assigned to the active preset). This tab also displays video parameters, which are of no use in this program.
You can set the program to save the target files in any folder you want, but you must change this parameter BEFORE selecting the files to convert, otherwise they will be saved in the default folder. You can customize the program's interface by using some of the included themes.
