CAVS to PVF Converter

CAVS is a set of coding/decoding standards developed by Workgroup of China in 2002. The technology is aimed to resolve problems of audio and video compression, namely original data and sources. This format is not widely supported on a PC, but is widely used for DVD-players and home theater systems in China.

PVF is a special low-bandwidth ADPCM-based digital audio format for recording and storing human speech. A .pvf file contains digitally recorded speech in the PVF format. Such .pvf files were mainly used with legacy voice modems and software-based answering machines. Often, to be used with a specific modem, a .pvf file would have to be converted into the device-specific RMD format. Currently, PVF audio files can still be played with several major media players as well as converted into other formats (like WAV) with multi-format converter tools.
