Maybe this is not the right place to ask, in that case
I apologize.

Justin, I thought you were the main force behind aften?
Now you're working on the ffmpeg AC3 encoder?
What does that mean for aften? Which encoder is
better now? Do you plan to drop aften once you're done
with improving the ffmpeg AC3 encoder?

Thanks, Mathias.
