How do I convert a WAV file to AU?

Upload your WAV file to the converter, select AU as the output format, adjust any parameters such as sample rate or bit depth if needed, then click Convert. Once the conversion finishes, download the AU file. The tool handles header conversion from RIFF to Au container while preserving PCM audio data.

Why convert from WAV to AU?

WAV is common on Windows, while AU is the native audio format for Sun/NeXT and Unix systems. Converting WAV to AU ensures compatibility with legacy audio editors, embeddable Java applets, and Unix-based media players. Both are uncompressed, so file size remains similar, but AU's simpler header makes parsing easier in resource-constrained environments.

How does the conversion handle specific audio attributes?

The conversion preserves PCM audio data, including bit depth (e.g., 16-bit or 24-bit), sample rate (e.g., 44.1 kHz), and channel count. Only the container header changes from WAV's RIFF to AU's 24-byte header. Codecs like ADPCM in WAV are decoded and re-encoded as uncompressed PCM in AU unless specified.

Is WAV-TO-AU free to use?

Yes, WAV-TO-AU on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Does this converter work on mobile phones and tablets?

Yes! WAV-TO-AU works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
