I have a bunch of OGG files that I would like to convert to WMA (v9) format.
Is there a native Ubuntu tool I can use for this? (Since WMA is a proprietary format, I'm guessing that there won't be a tool that does this in the repos.)
I have found a way to convert OGG files to WMA (v8) files using VLC:
I really don't know enough about encapsulation and audio formats, and I have no idea why you'd want to take something good and make it worse, BUT...
VLC appears to have the functionality you required.
Not a full answer, but hopefully something to start you off.
