i'm kinda rusty 'cause i can't install linux on my new mobo, but have you tried
sh Audiocoin-qt-ubuntu?
Ok, thank, I did tried sh Audiocoin-qt-ubuntu and the shell told me:
Audiocoin-qt-ubuntu: 2: Audiocoin-qt-ubuntu: Syntax error: ")" unexpected
typo?
?

Sorry I am not know it that you told
sh Audiocoin-qt-ubuntu will not work because it's not a shell script, hence the error you are getting.
So going back to your original error about not being able to execute binary file, this is likely because you haven't make it executable, because it won't be by default after extracting it. So:
sudo chmod +x Audiocoin-qt-ubuntu
./Audiocoin-qt-ubuntu
If you haven't done the next one already, you'll need to install it before executing the wallet or you won't be able to compile:
sudo apt-get install libminiupnpc-dev
