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.
The AC-3 audio encoding format supports between one and six channels with frequency ranges from 20 hertz to 20 kilohertz. The format contains frame headers which detail information about the rate of sampling, encoded channels, bit-rate among other details. It also consists of six audio blocks.
