AMR Converter Pro

AMR Converter Pro is an application which enables you to encode audio tracks between the AMR, MP3, OGG, WAV and WMA formats.
The interface of the program consists of a plain and simple-to-use interface in which you can import audio by using the file browser or "drag and drop" method (batch encoding is supported).
In order to initiate the conversion process, you simply have to specify the output destination and format.
Furthermore, you can modify settings for each aforementioned extension when it comes to sample frequency rate, channels, bit depth, encoder and encoder format, profile, and others.
In addition, you can add a folder to the list (optionally include subfolders), set AMR Converter Pro to automatically use the previous output folder, overwrite existing files, maintain folder structure and to delete the source files after conversion, and more.
The tool is fast when it comes to the encoding process. Plus, it uses a low-to-moderate amount of system resources and manages to keep a pretty good sound quality. Unfortunately, there is no help file available and the interface needs some major improvements to be up-to-date with modern standards.
Also, you cannot view a progress bar, elapsed or remaining time during the conversion, and no message pops up at the end. Even so, AMR Converter Pro is simple to work with and can be used by individuals of all levels.
