Free online WV to VOX converter

Source format

WV is the file extension for WavPack audio files, a lossless compression format used to store high-quality audio with no data loss. It is popular among audio enthusiasts, archivists, and users who want smaller files than uncompressed WAV while preserving the original sound exactly. WV files are often used for music archiving, mastering, and long-term storage.

Target format

VOX is a compressed audio format commonly associated with Dialogic/OKI ADPCM voice recordings. It is designed for speech and other low-bandwidth audio, not for high-fidelity music. VOX files are typically much smaller than WAV or WV, but they sacrifice a great deal of audio quality. The format is mainly used in telephony, voice logging, and legacy voice applications.

How to perform the conversion

The most practical way to convert WV to VOX is to use a desktop audio converter or an audio editor that supports both formats. Because WV is lossless and VOX is a low-quality voice format, the conversion is usually done only when you specifically need VOX for compatibility with older systems.

1. Open your WV file in a converter or editor that can read WavPack audio.
2. Choose VOX as the output format.
3. If the program offers codec settings, select the appropriate ADPCM/VOX voice encoding options.
4. Start the conversion and save the resulting file with the .vox extension.

In Audacity, if your version supports the needed import/export chain through installed libraries, you can open the file and then use File → Export → Export Audio to save in a compatible VOX-capable format. In many cases, a dedicated converter or command-line tool is more reliable for this specific conversion. If you only need a quick browser-based conversion, you can convert the file on 101convert.com for free, without installing any software.

For command-line workflows, a common approach is to first decode WV to an intermediate WAV file and then encode that WAV to VOX using a tool that supports VOX output. For example, with ffmpeg or another audio utility, the process may look like decoding to input.wav first, then exporting to output.vox if VOX encoding is available in your build or toolchain.

Notes on quality and compatibility

WV to VOX is a lossy conversion in practice because VOX is intended for voice-grade audio and cannot preserve the full fidelity of WavPack source material. Expect a major reduction in sound quality, bandwidth, and frequency range. This conversion is only appropriate if you need legacy VOX compatibility or are working with speech recordings where quality is less important than file size and format support.

Compatibility can also be limited because VOX support is uncommon in modern consumer audio software. Some programs may import WV but not export VOX, or they may require a specific VOX variant. If your goal is archival storage or music playback, it is usually better to keep the file in WV or convert to a more widely supported format such as WAV, FLAC, or MP3 instead.
