Type of format Digital audio
Description MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio that uses lossy data compression. It is a common audio format for consumer audio streaming or storage and a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players. M4R - is a digital multimedia container format used to store audio in mono channel mode. For example, the Apple iPhone uses MPEG-4 audio files (with .m4r extension) for its ringtones. The length of the m4r ringtone should not exceed 40 seconds. M4R and M4A formats shares many similar features.
Technical details Lossy compression is designed to reduce significantly the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio. For example, an MP3 file created using the setting of 128 kbit/s will result in a file about 1/11 the size of the CD file created from the original audio source.
