Wireless transmission audio

Hi, my name is Gianluca. I have to build-up a way of communication between a box and a car on track. The range that i have to cover is more or less 1km. Can i do this with 2 arduino and 2 xbee module? Once configured the connections between the arduino how i convert the signal to/from an headphones/microphone?

Thank you.

  1. The range: Xbee range ideal conditions

  2. Voice: amazingly, the answer is yes with conditions. Cornell experiment

But, IMO, this is not an optimal solution.
