Open M4R File

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.
