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.
Core Audio Format
This audio file container was created by Apples developers. CAF incorporates a huge amount of information: the artists name, the songs duration, the names of the album and track. In terms of size, files of the CAFformat can exceed 4 GB. After its emergence in 2005, Core Audio Format replaced AIFF and WAV. It has a lower compression ratio, so the quality of audio does not suffer as a result of compression. CAF files are often used to create various sound effects.
