About AU files
AU files are audio files developed by Sun Microsystems and NeXT for Unix-based systems. They are commonly used for storing and playing digital audio data. AU files are not as widely supported as other audio formats, such as MP3 and WAV, and can be difficult to work with.
The most common way to convert AU files is to use dedicated audio editing software, such as Audacity, Logic Pro, or Adobe Audition. These programs allow users to open AU files and convert them to other audio formats, such as MP3 and WAV.
When converting AU files, it is important to consider the quality of the audio. AU files are usually stored in an uncompressed format, which means they can take up a lot of space. If the audio is converted to a compressed format, such as MP3, the file size will be reduced, but the quality of the audio may suffer.
Another challenge with AU files is that they are not widely supported by most media players. This means that if you want to play an AU file on a device, you may need to convert it to a more widely supported format, such as MP3 or WAV.
Overall, AU files can be difficult to work with and may not be supported by all media players. For these reasons, it is often easier to use a free and easy online website such as Convert.Guru to convert AU files.
The AU Converter Story
The history of Convert.Guru began more than 25 years ago in California, when Tom Simondi published the most comprehensive database of file formats on his website. Before that, Tom had worked on Space Shuttle development at the Air Force Systems Command’s Space Division in Los Angeles. He is known as one of the top programmers of the late 1980s.
When Microsoft integrated Tom’s Filext database into Windows XP, it became the leading platform for analyzing and processing file types and formats.
Today, we use the latest technologies to analyze, process, and convert one of the world's largest collections of file formats. We are committed to developing the best AU converter by continuously improving quality, usability, and reliability.
