What is a .dvf file?
File extension details and usage information
The DVF (Digital Voice File) format is a proprietary audio file format developed by Sony, primarily used for their line of digital voice recorders. It is designed specifically for recording human speech, such as dictations, meetings, interviews, and lectures. Because it is optimized for voice, the format utilizes high-compression algorithms to keep file sizes small, which allows for extended recording times on devices with limited storage capacity. However, this focus on voice compression means that the audio quality is generally not suitable for high-fidelity music playback. DVF files are often associated with older Sony IC recorders and are frequently replaced by the newer MSV (Memory Stick Voice) or DSS (Digital Speech Standard) formats in more modern hardware. Because it is a proprietary format, it is not natively supported by many standard media players, often requiring specific Sony software or conversion tools to be played back or edited on a computer.
