A .caf extension file is a Coral Audio Format file. This format is quite advanced as compared to older formats of digital audio like .wav and .aiff. The .caf format files are of a very high resolution in terms of recording and editing as well as playback. They offer features like unlimited file size, excellent recording, multiple data formats, auxiliary data and data dependency support.
The AMV video file format is a proprietary video container which was created for Chinese made and video enabled S1 MP3 players and MP4 players. The goal of the format was to primarily lower the cost of hardware components and royalty fees required for video playback using other container formats on these video enabled devices. The .amv file type is a modified version of the more commonly known AVI multimedia container with the video codec being a version of motion JPEG (MJPEG) format.

A .caf format file uses 64-bit file offset technology that can save a large number of recorded audio files in different formats and metadata tracks. Apart from audio data, these files store information like text, channel layouts, markers and annotations. Programs like Logic Studio and Soundtrack Pro frequently use CAF format files for additional sound effects and surround sound audio compression.
An open source AMV encoder and decoder for windows exists but is not associated with the original developers of the format. The audio stream within AMV files is encoded using a variant of the Adaptive differential pulse-code modulation or ADPCM algorithm developed by the interactive multimedia association (IMA) but not in its strict form given the inclusion of an 8 byte seed at the start of every frame.
