Free online WV to AU converter

WV is a lossless audio format from the WavPack codec, used to compress high-quality sound without losing data. AU is an older audio file format originally used on Sun and Unix systems, often storing uncompressed or lightly compressed audio. Converting WV to AU usually means decoding WavPack audio and saving it in a more widely recognized legacy audio container.

Why convert wv to au

You may need this conversion for compatibility with older software, Unix-based tools, or systems that support AU better than WV. Since WV is less common, converting it can make playback and editing easier in certain environments.

Best software for conversion

The best choice is FFmpeg, because it supports both formats and can convert audio reliably from the command line. For a graphical option, Audacity can open many audio files and export to supported formats, though AU support may depend on your build and installed codecs.

Recommended workflow in FFmpeg: ffmpeg -i input.wv output.au

How to convert wv to au

1. Install FFmpeg on your computer.
2. Open a terminal or command prompt.
3. Run ffmpeg -i input.wv output.au.
4. Check the resulting AU file in your target player or editor.

Important notes

• WV is lossless, but AU may not preserve all original characteristics depending on the chosen encoding.
• If you need maximum compatibility, confirm the sample rate and bit depth supported by your target application.
• For batch conversion, FFmpeg is faster and more flexible than most GUI tools.

Alternative tools

• Audacity — useful for manual editing before export.
• VLC — can sometimes convert audio files, but is less ideal for precise format conversion.
• Online converters — convenient for small files, but not recommended for sensitive audio.
