What is the .MPR File Extension?

.MPR File Extension Description:

The most common usage of the file extension .mpr is as an audio stream for MPEG, which is usually utilized as a ringtone of the iPhone mobile device. The iPhone similar to the iPod also utilized the iTunes application, in order to move sound files between the computer (either running on Mac OS X or Microsoft Windows Operating System platform) and the device, via a USB cable connection. The file extension .mpr is recognized by iPhone as a format that it can use for its alert tones, aside from other supported audio formats.

To create an .mpr file extension format from an MP3 audio file under the Microsoft Windows Operating System environment, the iTunes for the OS must be installed. The source audio must initially be stripped down to shorten it to approximately 40 seconds or less, prior to dragging it to the iTunes library folder. Once added to the library, the audio file must be converted to AAC format as a step toward creating the .mpr file extension.

This process will create an MPA format file under the My Documents/ My Music/ iTunes Music/ folder, which can then be renamed to the file extension .mpr, and dragged to the Ringtones sub-folder to allow importing to the iTunes ringtones list.

Once the file extension .mpr is recognized by iTunes, it can then be transferred to the iPhone via the sync operation; users can then proceed to the Settings menu of the iPhone, choose Sound and the option Ringtone, where a custom group should appear that contains the newly transferred ringtone with the .mpr file extension.

For the Mac OS X, the process is essentially the same, with the main concept to be observed in the conversion process being the creation of the MPA format, which is an unprotected type prior to renaming it to .mpr file extension and transferring to iTunes, and then its eventual syncing with the iPhone.

Other uses of the file extension .mpr include being utilized as a report format for the Mass Properties in AutoCAD, which is extremely valuable in designing of objects that rely on specific densities. Invoking the MASSPROP from the Tools menu allows the application to calculate the object's center of gravity (combined), which is reflected in the .mpr file extension.

The file extension .mpr is also implemented as a dictionary file (FileMaker), project file (Multilizer), backup data (Music Publisher) and solutions menu (Visual FoxPro), which is a source code generated by the language for its menu program.
