Advanced Audio Coding (AAC)
This format stands for advanced audio encoding. Created as an alternative to mp3, it allows for compressing files at bitrates identical to mp3, obtaining high-quality sound. Files of the AAC format contain many sampling frequencies. Advanced Audio Coding includes 48 channels. This type of encoding is more efficient and includes a larger number of filters. Files of the Advanced Audio Coding format cut off the frequencies which the human hearing cannot perceive. This results in a reduction of the original file size.
