About DVF files
The .DVF file extension, standing for Digital Voice File, is a proprietary audio format primarily used by Sony IC Digital Voice Recorders for storing voice recordings. The core format is consistent, but key differences exist in the codec (compression method) and available recording modes based on the specific recorder series.

📝 Codec and Compression Details
The .DVF format employs two primary codecs depending on the recorder's capabilities:
- LPEC (Low-bitrate Proprietary Enhanced Compression): Used primarily in the SX and BP series, LPEC supports a wider range of bitrates, from high-quality stereo (48kbps) down to low-bitrate mono (6kbps).
- TRC (Target Recording Codec): Typically used in the P-series recorders, TRC focuses on maximizing voice recording time with very low bitrates (4.4kbps to 19.2kbps).
Converting DVF files to more common formats like MP3, WAV, or WMA is often necessary for ease of use. Software such as Sony's Digital Voice Editor is one of the few available tools that can convert DVF files. However, this software is only available for Windows and not actively maintained, which can pose compatibility issues with newer operating systems.
When converting DVF files, it's essential to consider potential challenges like loss of audio quality and the time-consuming nature of the conversion process. Additionally, DVF files might contain metadata that could be lost during conversion, which is crucial for organized storage and retrieval of audio data.
Given these challenges, using a reliable conversion service can be beneficial. While offline tools are limited, Convert.Guru offers an easy, drag-and-drop solution to convert DVF files to popular formats like MP3, WAV, OGG, and FLAC. Despite the drawbacks of DVF files, Convert.Guru provides a seamless and user-friendly experience, ensuring your audio files are accessible and compatible with your preferred devices.

The DVF Converter Story
The history of Convert.Guru began more than 25 years ago in California, when Tom Simondi published the most comprehensive database of file formats on his website. Before that, Tom had worked on Space Shuttle development at the Air Force Systems Command’s Space Division in Los Angeles. He is known as one of the top programmers of the late 1980s.
When Microsoft integrated Tom’s Filext database into Windows XP, it became the leading platform for analyzing and processing file types and formats.
Today, we use the latest technologies to analyze, process, and convert one of the world's largest collections of file formats. We are committed to developing the best DVF converter by continuously improving quality, usability, and reliability.
