How do I convert an AU audio file to WMV?

Upload your AU file, select WMV as the output format, choose audio quality (e.g., 128 kbps WMA), then click Convert. After processing, download the WMV file, which contains your audio as a Windows Media Audio track in a video container. For batch conversion, select multiple AU files to convert them all at once.

Why convert from AU to WMV?

AU files are rare Unix/NeXT audio files using PCM or µ-law encoding, often unsupported by Windows Media Player and modern editors. Converting to WMV wraps the audio in a Microsoft-supported container, allowing native playback in Windows, easy streaming, and smaller file sizes with WMA compression.

How does the AU to WMV conversion handle audio attributes?

During AU to WMV conversion, the audio is decoded from its original PCM or µ-law encoding and re-encoded to WMA (typically 128–320 kbps). The sample rate (e.g., 8 kHz to 48 kHz) is preserved, but the codec change may introduce minor generation loss due to WMA compression. If the AU file contains metadata, it is retained in the WMV container where possible.
