Files with the extension MP2 contain audio encoded with the standard MPEG I Layer II.
This lossy compression method is not identical to the popular MP3.
MPEG I Layer II is still the standard for digital TV and radio sound.
It supports one or two channels, sampling rates from 32 to 48kHz and bitrates from 32 to 320kbps.
Files with the extension MP2 also sometimes contain audio data encoded with the mostly backwards compatible MPEG II Layer II. This extension of the MPEG I Layer II standard supports additional bitrates and sampling rates as well as multi-channel audio.
The extension MP2 does not designate MPEG II video files, although this ending is occasionally mistakenly used.
Most often resolving problems with opening MP2 files is very simple. Just install an appropriate program that supports such files. All of the listed programs support MP2 files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of MP2 files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate MP2 files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the iTunes applications is not on the list, select "Browse" option in order to manually locate the directory where iTunes has been installed.
Sometimes problems with opening MP2 files may not lie with the application itself, but can arise due to other causes, such as:
