The format within the MPEG-4 Part 14 standard
Created in 1988, it was intended for video files. A file of this format contains video and audio information, images and subtitles. When compressed, the files do not lose quality. The format includes various types of multimedia content: videos, animations, audio, 2D and 3D graphics. Files of this format can be used and viewed on the Internet. In this case, a metadata transfer takes place. The full name of the format is MPEG-4 Part 14.
AMR (Adaptive Multi Rate): adaptive encoding with variable bitrate
This information compression format allows for optimizing speech encoding. Files in the Adaptive Multi Rate format can be created using phones and smartphones. AMR files are mostly used for voice recordings. The main advantages of the format are the large number of encoding and decoding rates, as well as the small size of the resulting content. With the help of appropriate software, an Adaptive Multi Rate file can be converted into any other audio format.
