In the further part of this page we have added a list of programs that should open your AU file. It is enough you choose a proper application for your operating system, download and install it.

Description

The file extension AU is used for audio files in AU format. It is the standard audio format on Sun and NeXT computer systems. The AU format is a container format that can include, but is not limited to, uncompressed LPCM (Linear Pulse Code Modulation) audio in mono or stereo, as well as various compressed data types.
The most commonly used audio format for AU files is compressed 8-bit μ-law.
The audio editing program Audacity can also handle AU files when ffmpeg is installed. It should be noted that many programs can not handle all data types of the AU format.

How to open a AU file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the AU file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a AU file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support AU files. At this point we are looking for disk space where the application was installed in and we can link it with a AU file. Since then, our operating system will use the selected program to support all AU files.

Other issues

Despite the described problem with AU there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the AU file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the AU file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
