How do I convert an AU file to WAV?

Click the upload button to select your AU file, choose WAV as the target format, and hit Convert. After a few seconds, download the output WAV file directly to your device. No extra software needed.

Why should I convert AU to WAV?

AU files are common in older Sun/NeXT Unix environments, while WAV is the standard uncompressed audio format for Windows and is supported by all major DAWs, video editors, and media players. Converting AU to WAV ensures your audio plays universally without codec or container issues.

Does converting AU to WAV lose audio quality?

For uncompressed PCM AU files, the conversion is sample-perfect: sample rate, bit depth, and number of channels are preserved exactly. If the AU file uses a compressed codec such as G.711 µ-law, it is decoded to raw PCM before being stored in a WAV container, so no additional generation loss is introduced.

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