Apple iPhone Ringtone (M4R) is the file format Apple uses to store ringtones on iPhones. The maximum length of an M4R file is 40 seconds. The only difference between M4R and MPEG 4 Audio (M4A) is the file extension, which lets an iPhone know M4R is a ringtone instead of a song.

 

How to open an M4R file?

As a format deployed by Apple for iPhone ringtones, M4R files open on iTunes by default.

 

Alternatively, Apple iOS is another good choice for opening M4R files. To create a custom ringtone, simply save an M4A file as an M4R file, and then import it into the iPhone.

Free Lossless Audio Codec (FLAC) is a file format that shrinks an audio file’s size, which, as the word “lossless” in the name implies, results in no loss in audio quality or original data. FLAC accomplishes this by using an algorithm that compresses the file to approximately 50 to 70 percent of its original size.

 

How to open a FLAC file?

The default program for opening a FLAC file is VLC media player. Other details about FLAC include that it is unpatented, permits music reproduction, is compatible with Telephony Application Programming Interface (TAPI), and is not subject to digital rights management (DRM).

 

Additionally, codecs that can implement FLAC include FFmpeg, Flake and FLACCL for encoding, and Audiocogs for decoding. Lastly, as the word “free” in the name suggests, FLAC is open-source software.
