Reddit reviews Game Audio Implementation: A Practical Guide Using the Unreal Engine

Download Unreal Engine 4, Unity... Really any modern game engine since they're so freely available these days, and play with it a bit.

I've had this book recommended to me, and my professor called it addictive, so at the very least it has that going for it.

Also check out WWise, a game audio engine that is highly compatible with various engines and platforms.

I also use UE4 and I just finished the book Game Audio Implementation which I learned a lot from.
