Apple iTunes Music Store (M4P) file is an Advanced Audio Coding (AAC) file that protects its content with Digital Rights Management (DRM) technology. Essentially, Apple uses this file format to prevent unauthorized use of the music files that are available for download from the iTunes Music Store. The specific name of Apple’s DRM protection is “FairPlay,” which is precisely what protects the content in M4P files.

 

How to open an M4P file?

Since M4P files protect iTunes files, naturally the default program for opening them is iTunes. The cross-platform option, which includes all popular operating systems and mobile, is VLC media player.

 

On Windows, several other options are available, such as MediaMonkey, Winamp, and Helium Music Manager. On Mac OS X, QuickTime is a good option. If there is a problem playing the file on a device, then use Aimersoft DRM Media Converter for Windows to remove DRM protection.

Adaptive Multi-Rate (AMR) is a compressed audio file that is often used for speech coding. The AMR speech codec focuses on narrowband signals, which makes it ideal for voice recordings and radio. It is used regularly in Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS).

 

How to open an AMR file?

Since AMR files are often used on mobile phones, including for MMS messaging, most 3G mobile devices are able to open them. AMR also opens with VLC media player, QuickTime, RealPlayer, and Xine.

 

Other software, such as the free audio-editing software Audacity, can open AMR files. Download audacity easily at SourceForge.net. Because AMR files are heavily compressed and focused on narrowband signals, they are not suitable for music files.
