WV to AU Converter
Processing entirely on your device — large files may take a moment.
Converting AU to WAV preserves the samples in a format every modern tool reads. If your files are still in WV format, this page is the shortcut: WavPack is the hybrid lossless format — its unique lossy-plus-correction mode ships a small file that can be restored to bit-exact audio.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the WV format
WavPack's signature trick is the hybrid mode: encode once into a small lossy .wv plus a tiny .wvc correction file — together they are bit-exact lossless, apart the small file plays like a high-quality MP3. It also offers pure lossless and pure lossy modes in the same container.
Full WavPack files decode losslessly through ffmpeg into FLAC or WAV; hybrid correction files are handled by the original encoder only, so a .wvc alone cannot be restored.
+ Strengths
- ✓Unique hybrid lossy+correction mode
- ✓Fast decode, open source
- ✓Error-robust streaming modes
! Limitations
- −Ratios slightly behind APE
- −.wvc correction files are orphaned here
- −Hardware support rare
About the AU format
AU is Sun Microsystems' audio format from the Unix workstation age: a small header followed by µ-law (or PCM) samples. Java's applet era shipped it everywhere, and old Unix sound tooling still emits it.
Modern players increasingly skip it. Converting AU to WAV preserves the samples bit-for-bit while moving the file into universal territory — the standard rescue path for system sounds and old recordings.
+ Strengths
- ✓Simple, lossless sample storage
- ✓Native to old Unix/Java tooling
! Limitations
- −µ-law flavor sounds dated and mono
- −Dropped by modern players
Why convert WV to AU?
Think of it as moving your file to the container that fits the job. Ratios slightly behind APE AU works differently: Simple, lossless sample storage If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this WV to AU converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for WV to AU?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
Can I convert a whole folder of WV files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
