AMR Converter Pro is an application used for encoding audio tracks in formats such as WMA, OGG, AMR, WAV, VOX, PCM, A-LAW, MP2, AIFF, ALAC, M4A, CD, MP4, FLAC, u-LAW, ADPCM, RAW, AU, AC3, and MP3. AMR bitrate and frequency have to be designated when converting into AMR. Specific files and entire folders can be converted by the program. Recursive subfolders can also be used with the program. Decoder and encoder options are also available. Good sound quality is maintained in outputs.
The program’s interface is minimal and easy to use. A Help file is not provided. However, advanced and novice computer users can easily understand the program and its functions. Audio import is done via a drag and drop facility or through a file browser. Encoding by batches is also provided. Users have to designate the output format and destination to be used in a certain project. Settings that can be modified include encoder format, overwrite protection, channels, profile, bitrate, bit depth, logging, and sample frequency rates. Program options include overwriting existing files, deleting source files post-conversion, maintaining folder structure using most recent output folder, and adding folders or subfolders to the queue list. Remaining and elapsed time, as well as the progress bar cannot be accessed during conversion. The program runs on a small to moderate quantity of a computer system’s resources.
