How do I convert WMA to AU using this online tool?

Upload your WMA file by dragging it into the conversion area or selecting it from your device. Set the target format to AU, then click the 'Convert' button. Once the conversion completes, a download link for your AU file will appear. The entire process runs in your browser, so no additional software is required.

Why should I convert WMA to AU instead of keeping WMA?

WMA is a lossy format optimized for Windows Media, while AU is an uncompressed PCM format supported by legacy Unix systems, Java applets, and many audio editing tools. If you're working with old Sun Microsystems hardware or need a format that's universally readable in these environments, converting to AU ensures compatibility. Note that AU files are larger due to the lack of compression.

How does the WMA to AU conversion affect audio quality?

The conversion preserves the sample rate (e.g., 44.1 kHz), bit depth, and channel count in the resulting AU file. However, WMA's lossy compression has already removed some audio data, so the output reflects the quality of your source WMA, not the original uncompressed recording. You won't get 'extra' quality back, but the conversion will be transparent relative to the WMA file.
