File Extension m4r Details and Technical Info

M4R files are more technically known as MPEG-4 type ringtones. It is a proprietary extension of sound files mainly associated with Apple's iPhone.

It is a unique file extension created by Apple to be used as a ringtone on its iPhone devices.

The M4R format is a high-quality compressed audio file, which uses only AAC (Advanced Audio Coding) as its default compression standard.

Note that the AAC is justly known for its incredible audio quality and significantly reduced file size.

Belonging to the MPEG-4 standard group, this audio file contains numerical representations, audio files and text in ASCII format.

Technically, M4R is equivalent to the popular M4A format except that M4R files could be protected by copyright based on Digital Rights Management (DRM).

Technicians can assert that M4R is a version of M4A, due to the lossy compression algorithm that characterizes the file.

Some features of M4R

  1. The length of M4R files is up to 40 seconds, ideal for ringtones.
  2. Apple created M4R to differentiate the tones of songs on the iPhone.
  3. In the iTunes store, the M4Rs are for sale, so they are not free.
  4. M4R files are created solely from a song purchased from iTunes as long as the file itself supports the creation of tones.
  5. When you buy an M4R file, it is automatically transferred to your iPhone after syncing.
