M4R to WMA Converter

M4R (MPEG-4 Part 14)

M4A is an audio file compressed using MPEG-4 technology, which has a lossy compression algorithm. The M4R file contains the ringtone in the M4A MPEG-4 file format, which uses the default audio format to store the song in the iPhone. The M4R format, like M4A, is designed to download audio to Apple devices through iTunes. Such a file can be created by converting other formats or uploading it from the official iTunes store. You don't have to look for converters or special programs, you can make m4r from m4a using standard tools of any operating system by changing the last letter of the extension manually. But for this to work like an iPhone ringtone, remember that it can only be created from songs purchased from the iTunes music store.

WMA (Windows Media Audio)

The WMA extension is a proprietary audio file compressed using Windows Media Compression. It is a proprietary format developed by Microsoft. This file is both an audio codec and an audio format. This file format was created by Windows to compete with other popular compressed audio formats. We must pay tribute to Microsoft: using their virtually unlimited resources, they have achieved the implementation of support for their brainchild in almost all hardware and software players. Microsoft has implemented support for DRM in WMA, a digital copyright management system that allows you to sell protected songs using special services. There are many WMA sub-formats, including WMA Pro, a lossy codec that supports high-resolution audio; WMA Lossless, a lossless codec that compresses audio without losing quality; and WMA Voice, a lossy codec designed for applications that support voice playback.
