How do I convert a WMV video to an AU audio file?

Upload your WMV file, choose AU as the target format, set your preferred sample rate (e.g., 44.1 kHz) and bit depth (e.g., 16-bit), and hit Convert. The system will decode the video's audio track and encode it into a .au file. You can then save the output to your device.

What is the advantage of converting WMV to AU over keeping the original WMV audio?

WMV is a container for video and audio, usually using codecs like WMA or MP3 for sound. AU files are raw audio (PCM or u-law) supported by many legacy Unix programs, embedded systems, and telecommunications hardware. Converting to AU ensures playback compatibility without requiring Windows Media components, and u-law encoding can significantly reduce file size compared to WMA at similar quality.

Will my WMV file’s audio quality change after converting to AU?

The converter decodes the compressed audio to uncompressed PCM before wrapping it in AU. This means the output preserves the original sample rate and channels, and it doesn't introduce additional lossy compression. However, if the source uses WMA lossless, the conversion is bit-perfect; if it uses a lossy codec like WMA 10, the decoded PCM reflects the lossy source. No metadata tags are transferred, but audio integrity is maintained for editing.
