Agree Free MP3 to M4A AAC Converter

There are many applications out there that are designed for audio conversion. Agree Free MP3 to M4A AAC Converter has a pretty self-explanatory title: it encodes MP3 files to AAC, AC3 and M4A.
The program's interface is pretty basic, so users with any experience level can easily manage it. You are required to add MP3 files to the conversion list (drag and drop is supported), select output directory, choose profile setting, and start the encoding process.
You can select the profile (low, acceptable, normal, excellent or superb quality, or retain original data) and you can select audio quality, sample frequency, channels and volume. Unfortunately, changing video size, video quality and frame rate is only available in the full version.
Moreover, because this is the demo version of Agree Free MP3 to M4A AAC Converter, only a small part of the files is converted. The conversion process is very quick, but that's precisely because it is a partial conversion.
The output of the longer file had a time length of three minutes, while the shorter audio track resulted in a 2-second song. Furthermore, the program was not able to recognize one MP3 file we tried to convert.
The bottom line is that the demo version of Agree Free MP3 to M4A AAC Converter has very strict rules, and we could not accurately evaluate this product. But it uses a very low amount of system resources, and you can access the developer's website to download various codecs.
