Cool MP3 To AAC Converter is a free audio encoding tool that will allow you to transform your MP3 files into the MPEG format AAC. You can select and convert any number of files in a single operation, using this tool’s batch conversion capabilities. The simple interface offers a number of quality presets to make the whole conversion process easier and faster.
AAC is a high-quality lossy audio codec that has been adopted by some Apple tools, being extensively used in both iTunes and iPod. When compared to MP3, AAC provides audio files of higher quality, allowing for up to 48 simultaneous audio channels instead of the two offered by MP3. However, when using this conversion tool all these superior quality audio properties will regrettably go unnoticed, as the original limitations of the MP3 input files cannot be avoided. When conversion from MP3 to AAC is still necessary for format compatibility reasons, you can rely on Cool MP3 to AAC Converter to perform the task fast and neatly.
The preset quality settings available (ranging from “very high” to “very low” quality) makes this tool suitable for all kinds of users. For those who would prefer to decide on a specific bit rate, there is also a “Custom” preset that will send them to a list of values going from 32 to 1024 (note that most of these values are completely useless when it comes to AAC files). The level of quality selected will be applied to all the MP3 files you convert using its batch capabilities. On a comic note, once the conversion process has finished, a message will pop up letting you know that your “videos” have been successfully converted.
