Convert MPEG to M4R

Converting one file format to another may be necessary for various reasons. So, for example, you may want to convert MPEG to M4R if your computer, phone or other device does not support MPEG format. Also, conversion is often required to reduce the file size, since the original format takes up too much space in the device's memory. Perhaps you just need to extract the audio track from the video file, in which case converting the video to audio format is a good option. In any case, with the help of our converter, you can easily complete the required task. Below you can find out some details about the original and new file formats.

In January 1988, an expert working group on coding of moving images was formed within the framework of the joint information technology technical committee JTC1 of the International Organization for Standardization ISO and the International Electrotechnical Commission IEC, which was tasked with developing standards for image and sound coding with the aim of eliminating redundancy. MPEG compression standards were developed by Moving Picture Experts Group. This technology defines the compression standards for both audio and video information and makes it convenient for transmission in broadcast. There are many versions of the format - MPEG-1, MPEG-2, MPEG-3, MPEG-4, etc. MPEG-1 is a lossy compression standard for video and audio. It is designed to compress VHS. Perhaps everyone is familiar with the MPEG-2 format. It is this format that underlies DVD-Video discs. The MPEG-2 format is also the basis for digital television standards. The MPEG3 standard was originally developed for use in High Definition Television (HDTV) systems with a data rate of 20-40 Mbps. The new MPEG4 standard, which appeared at the very end of 1999, offers a broader view of media reality. The standard defines the principles for working with content (digital representation of media data) for three areas: interactive multimedia itself (including products distributed on optical discs and over the Internet), graphics applications (synthetic content) and digital television (DTV).

Ringtones for Apple devices have a special format - m4r. In order to get a ringtone in this format, we need the original file (in MP3 or other audio format) and iTunes. That is, all the ringtones that you download to the iPhone will look something like this - RingtonName.m4r. The M4R format is also used in ringtones for iPads and iPod touch players. If one day you want to make yourself a ringtone using the iTunes program, then you will be faced with the fact that you will need to change the file extension from .m4a to .m4r. For those who have been using a computer for several days, this will not be difficult. Music in M4A can be directly set as iPhone ringtone by changing the file extension from M4A to M4R in iTunes. This codec was created to provide lossless decoding and save space on memory. The M4R format, like M4A, is for downloading audio to Apple devices via iTunes. The main difference between M4R and M4A is that once downloaded to your phone, M4A files are displayed in the Music section, while M4R audio files can be used as ringtones. Therefore, it is better to save your favorite audiobook in M4A format, and a funny ringtone in M4R. The M4R format, which is an MP4 container that packs an AAC audio stream, is used as ringtones in Apple iPhone. Therefore, a rather demanded direction of converting is the conversion of the popular music format MP3 to M4R.
