Cool Free Music Converter is a tool that allows you to encode audio tracks between the MP3, AAC, AC3, AMR, M4A, OGG and WAV format.

The user interface of the program is clean and intuitive. You can add a file by using the file browser or the "drag and drop" method, and view its source path, size and length.

Once you have selected a preferred output format, you can configure settings which revolve around the profile, video size, quality, frame rate and aspect, as well as audio quality, sample frequency rate, channels and volume.

In addition, you can check the option to show the output destination or shut down the computer once a task has been completed.

But you can also clear the queue in order to add a different file. Once conversion has been initiated, you can view a progress bar, but you cannot check out elapsed time or estimated time remaining.

The program uses a very low quantity of CPU and system memory, finishes a task in a short amount of time (it depends on the type of output format you have selected) and doesn't require installations of any third-party software (i.e. codecs).

However, Cool Free Music Converter doesn't include a help file and batch conversions are not supported in the free version (which is the software's biggest disadvantage).

All in all, this application is extremely easy to use, even by beginners, and we strongly recommend it if you want the quickest way to convert audio files.
