Is there such a thing as Audio Book ARC's?

Just wondering....

 

I get my fair share of paper arc's and have more than is healthy in e-book arc's but after listening to an audio book today I got to wondering if there's such a thing as somewhere that offers audio arc's for review?  Do any publishers offer those as arc's?  If so, where?  I'd love to get in on that!

 

I think those would be my definite first choice of arc fomat, if there was such a thing...
