This is a freeware utility that converts M4A to MP3 and other audio formats. This free tool is mainly for your try out, so that you get a feel of the other products from the same company. This converter can be fed any combination of AAC, M4A, OGG and WAV formats as an input. It is possible to produce AAC, M4A, MP3 or WAV files in the output. The interface is simple and should not prove to be a challenge for any user. The drag and drop features help make the operation quick and easy. For creating the batch list, you can add files or a full folder. Before finalizing the list, you could remove items that you did not really want to be processed. All the files in the folder will get added to the batch list. You need to specify the output path before starting the conversion.
It is possible to shuffle the files. You can keep the original folder structure, of course. Output file format is user selectable. Output bit rate could be selected from a drop-down list. You can ask the utility to delete the source files after the conversion is done. It is possible to specify actions in case the output folder already exists. One such option would be to open another folder in case the specified folder exists already to avoid destruction of the contents of the original folder. Output file size could be specified. This is a good tool.
