ATRAC stands for Adaptive Transform Acoustic Coding Audio File. This file belongs to the family of audio compression process. This kind of file format is being developed by Sony Minidisc. This is one of the best and first commercial audio products launched in market. This file formats allows only ATRAC devices to be operated as ATRAC devices only accept small size disc. This would also have same time of running as similar to the CDs.
These procedures were developed with the close contact and close cooperate with the engineers of LSI developments that are also working in Sony Company.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .AA3 file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .AA3 file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .AA3 file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
