To prepare and use the -audiofile option

To extract the audio from the video file, use a video or audio editing tool (such as VidEdit, Sound Forge, or AVIEdit).
Open the extracted audio file in Microsoft Windows Sound Recorder (or any audio editing tool on your computer), and compress the audio with one of the available codecs.
When converting the video file to an .asf file, use the newly compressed audio file in the -audiofile option.
```
VidToASF -in {filename.avi | filename.mov} -audiofile {filename.wav}-out filename.asf
```

Note

When compressing the audio, use one of the standard codecs provided with the Microsoft Windows operating system or with Microsoft Windows Media Player. If you use a codec that is not resident on the user's machine, the user will not receive the audio content when playing the .asf file.
