Cool Free Audio to AMR Converter

As its name suggests, Cool Free Audio to AMR Converter allows you to turn audio files (MP3, AAC, M4A, OGG, WAV) into AMR. But it can also extract the audio stream from videos (e.g. 3GP, ASF, AVI, FLV, WMV) and save it to AMR.

The interface of the app is plain and simple to work with. Media files can be imported into the file queue by using only the file browser because the "drag and drop" method is not supported. Processing multiple entries simultaneously is possible.

In the file queue you can find out the source path, size and time of each item. Since the standard settings cannot be changed, all you have to do is simply establish the output directory, in order to proceed with the encoding operation.

You can remove an item from the list or clear the entire file queue, as well as set Cool Free Audio to AMR Converter to turn off the computer or to open the output directory once all tasks are done.

The audio processing tool needs a low amount of CPU and system memory to finish a task quickly. It has a good response time and outputs tracks with a good sound quality. We have not encountered any issues during our testing; Cool Free Audio to AMR Converter did not freeze, crash or pop up errors.

On the other hand, you cannot configure audio settings (e.g. quality, frequency, channel mode, volume level), specify the thread priority or preview tracks in a built-in audio player. There is no user documentation available. Cool Free Audio to AMR Converter has not received updates for quite some time.
