ABC Amber Audio Converter is limited to two basic functions. The freeware convert music between MP3 and WAV. Converting the widespread Soundfiles works both ways. In addition, ABC Amber Audio Converter processed thanks to its batch processing multiple pieces of music in one go. ABC Amber Audio Converter does not need any bells and whistles and remains in its system requirements therefore very slim. Advanced features such as settings for bit rate and the like, however, one looks in vain in the freeware.
