How to open AT3 file?

The most common problem when using ATRAC3 Audio Format is that a specific AT3 is not associated with the program. This causes the file AT3 to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the AT3 file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install SonicStage

The first step is to check if the computer has the SonicStage program installed. The easiest method is to use the system search engine by entering the program name SonicStage in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support AT3 files.

Programs to open AT3 file

Remember to download programs supporting AT3 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of SonicStage with AT3 files

If the application is or has been freshly installed, but the AT3 file still does not use the SonicStage program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the AT3 file with the SonicStage program.

Step 3. Update SonicStage to the latest version

If, despite the association of the SonicStage program with the ATRAC3 Audio Format file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Sony Corporation page and install.

Step 4. Check for the following problems with the AT3 file

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. Usually this applies to AT3 files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our AT3 file. However, remember that not every infected AT3 file can be recovered, so it is important to take care of regular backups.
Older version of AT3 file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair AT3 file corruption. You can restore the file from a backup or use Sony help.
The program can also signal the fact of encryption. The encrypted AT3 files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. Copying the AT3 file to another location will fix the problem.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file AT3 to close. Some anti-virus or backup software may occupy the AT3 file for a certain period of time. If nothing helps, please reset the device.
