M4R to WAV 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.

WAV (Waveform Audio File Format)

The WAV format is designed to work with a digitized audio stream, contains musical compositions, voice recordings and various audio effects. It is the best audio format for processing and storing uncompressed audio data that is similar in quality to CDs. One minute of sound in it weighs about 10 MB. WAV occupies a significant amount of memory space, much more than other popular formats, so very few people use this format to store their own audio library on a computer. The Wave format is needed for the release of a disc, LP, download for sale on sites, and must be with the parameters of 16 bit 44.1 KHz. It is also used in audio editing programs to save time on compressing and decompressing data. The WAV format is only a container file, and the audio content is compressed using a wide variety of codecs.
