AU format for reliable data storage
This audio format was developed by Sun Microsystems. It is intended for storing audio files; the file itself consists of three components: the header, the annotation unit, and the audio file itself. What distinguishes this format is the small file size, due to which its sound quality is low. It can be converted into other formats, such as mp3 or MPEG. Although this format is mostly used on personal computers that are powered by operating systems Sun or Unix, AU files can also be opened using other audio players.
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.
