How do I convert an AVI video to an AU audio file?

Go to the AVI to AU converter on LetsConvert, click the upload button to select your AVI file. Once uploaded, choose AU as the target format and click 'Convert'. The audio stream will be extracted and encoded into a Sun Audio (.au) file. Finally, download the converted AU file to your device.

Why should I convert AVI to AU instead of keeping the video file?

AVI is a video container that includes video and audio tracks, so it takes up significant storage. AU is a dedicated audio format commonly used in Unix-based systems, Java applets, and embedded applications. Converting to AU leaves only the audio, dramatically reducing file size and ensuring compatibility with audio-only software that cannot read video containers.

Does the AVI to AU conversion affect audio quality or metadata?

The converter decodes the audio stream from the AVI container and writes it into an AU file using PCM encoding, preserving sample rate, bit depth, and channel count. However, if the AVI uses compressed audio such as MP3, it will be decoded to raw PCM, which increases file size but retains original quality. Metadata like artist or title is not carried over, as AU format stores only raw audio data.
