Converter MP4 to AU

MP4 is an abbreviation for MPEG-4 Part 14. It can also be called MPEG-4 AVC. In this case, the abbreviation AVC (Advanced Video Coding) is an advanced video encoding. By the name of the format, it is easy to guess that it is necessary for working with video files. The format was first proposed in 1998. Since then, MP4 is considered one of the most common file formats used to store and transmit multimedia. MP4 is a container format that provides the ability to combine audio, video, subtitles and pictures in one file. It is also suitable for posting rich content. Say three-dimensional graphics, menus and interactive features. There are many portable players and other devices that play MP4. For this, a PC or laptop is also quite suitable. The MP4 format is a robust application that needs relatively low performance. And therefore, users could use such a tool for their own purposes. This tool has found wide application, as the technology for the production of more and more powerful devices, both portable and desktop with a large hard drive capacity, is constantly evolving. Due to the fact that the speeds of various types of connections to the global network are increasing, MP4 has become more affordable. It acts like the MP3 format, although it is more complex. The format compresses files and remains high-quality.

AU is an audio file format created in Audacity. This is a free cross-platform program designed to edit audio files. AU format (Audio Units) was developed by Sun Microsystems. This format greatly simplifies the task of reliable storage of audio files. An AU file consists of 3 parts: a header (max. 24 bytes), a description block of various sizes, and audio data. The file format is used on computers running the Sun or Unix operating system. However, it opens with other audio players. The AU format uses the logarithmic encoding method, previously very popular on computers running the Sun SPARCstation operating system. Previous sound file formats, in order to reduce the size, used the logarithmic scale of recording samples. Among the representatives of such formats, the Sun AU group of formats, which are still in action, gained great fame. Problems with opening the AU file usually manifest themselves when there are no corresponding applications that would be installed on the PC. Applications that use .AU files are Apple QuickTime Player, Microsoft Windows Media Player, Real Player, Winamp, and other widely used audio players. And this is the vast majority of professional audio editors.
