Conversion Quality Deep Dive
Quality in this conversion depends primarily on your source file. A high-quality WAV Audio input produces an excellent AU Audio output. Since the target format is lossless, output quality matches your input exactly. WAV Audio encodes data using mathematical algorithms that preserve every data point. AU Audio prioritizes exact data preservation. The conversion maps between these approaches intelligently. WAV Audio's known limitation — extremely large file sizes (10MB per minute at CD quality) — is resolved when converting to AU Audio, which offers simple format with wide Unix/Linux tool support.
Audio conversion from WAV Audio to AU 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 WAV to AU conversion applies format-appropriate algorithms to ensure maximum data fidelity. CD quality: 44,100 Hz sample rate, 16-bit depth, stereo = 1,411 kbps

Xonvert is a browser-based tool without a server API, since all processing happens client-side. For automated conversion, you can use Xonvert's PRO features or integrate the underlying open-source libraries directly.
Are my files uploaded to a server?▼
No. Zero files are transmitted anywhere. Xonvert processes everything using client-side JavaScript and WebAssembly. Your files stay on your machine.
Can I preview the AU output before downloading?▼
Yes. Xonvert shows a preview of your converted file so you can verify the result before saving it to your device.
Can I convert password-protected WAV files?▼
Encrypted or DRM-protected files cannot be converted. You'll need to remove protection first using the original software.
Can I convert multiple WAV files at once?▼
Yes! Drag multiple files into the converter for batch processing. All files convert simultaneously and can be downloaded as a ZIP archive.
What's the maximum number of files I can convert at once?▼
Free users can convert several files per batch. PRO users enjoy unlimited batch sizes. For very large batches, your device's memory is the only practical limit.
Why choose AU over other formats?▼
AU Audio offers simple format with wide Unix/Linux tool support. It's widely used for Unix system sounds, telephony and basic audio processing, making it an excellent choice for most audio needs.
