Converting software?

[ItsAdot]

I'm looking for a simple program that can convert audio tracks from mkv files.

Like DTS to AAC or MP3 and that stuff.
I had one about 3 months ago but I lost it, it did the job in less then 10min for a 1080p movie of 14gb. I cant find it anymore
It was so easy, i tried several ones now but they all they take 2h+.

Ideas?
