Convert AU to WV
Fast, free, and secure AU to WV conversion. No registration required.
Whether you have one au file or fifty, converting them all to wv takes just seconds with Xonvert's browser-based engine. Your source file uses AU Audio encoding (standard since 1980s). The output will use WavPack Audio encoding (available since 2002). This particular format pair is popular among musicians and podcast producers who need reliable, fast conversion. The entire conversion pipeline runs in a sandboxed WebAssembly environment for maximum security and performance.
Advantages of WV over AU
There are strong reasons to convert AU to WV:
Industry standard: In many audio workflows, WavPack Audio has become the go-to format, making this conversion a frequent necessity.
API and automation: Many automated workflows and APIs expect WavPack Audio as input, making this conversion necessary for programmatic processing.
Editing flexibility: WavPack Audio files can be opened in a wider range of editing software, giving you more options for further modifications.
Collaboration ease: Team members and collaborators are more likely to have software that opens WavPack Audio natively, reducing compatibility friction.
Smaller file size: Efficient compression in WavPack Audio often produces significantly smaller files than AU Audio, saving storage space and bandwidth.

AU to WV: Quality Comparison
Xonvert's conversion engine analyzes your AU Audio source and selects the optimal encoding strategy for WavPack Audio output. Simple header: magic number, data offset, size, encoding, rate, channels Supports up to 32-bit integer and 32-bit float samples These implementation details are handled automatically by the converter. A/B testing confirms that Xonvert's AU Audio to WavPack Audio output is indistinguishable from reference-quality conversions produced by leading desktop software. The WebAssembly engine uses identical codec libraries. Originally for Sun Microsystems workstations Hybrid mode: lossy .wv + correction .wvc = lossless together These technical characteristics influence how quality is preserved during conversion.
Audio conversion from AU Audio to WavPack Audio focuses on preserving sonic fidelity while adapting to the target format's characteristics. Both formats are lossless, guaranteeing a bit-perfect audio transfer with no quality change whatsoever. Sample rate, bit depth, and channel layout are preserved when supported by the target format.
The AU to WV conversion applies format-appropriate algorithms to ensure maximum data fidelity. Supports mu-law, A-law and linear PCM encoding

AU to WV FAQ
Can I undo a conversion?▼
Since your original AU file is never modified, there's nothing to undo. Your source file remains exactly as it was — only a new WV copy is created.
What if my AU file won't convert?▼
Ensure the file isn't corrupted or DRM-protected. Try a different file to verify. If issues persist, the file may use an unsupported codec variant.
How many times can I convert AU to WV per day?▼
There's no daily limit for free users. Convert as many files as you need, as often as you need. PRO users get additional batch processing features.
Can I use this converter for commercial purposes?▼
Yes. There are no restrictions on how you use your converted files. Convert AU to WV for personal, educational, or commercial projects freely.
Can I convert WV back to AU?▼
Yes! Xonvert supports reverse conversion too. Visit the WV to AU converter page to convert back.
Can I convert AU to WV without losing transparency?▼
Transparency is a concept specific to image formats. For audio files, all content data is preserved during conversion.
Is WV better than AU?▼
Neither is universally "better" — they serve different purposes. AU Audio excels at simple format with wide Unix/Linux tool support. WavPack Audio is stronger in unique hybrid mode creates lossy + correction file pair. Choose based on your needs.
