It sure sounds pretty, but you can find real clips of cricket calls slowed down (which are amazing in their own right, but sound nothing like this). Sorry to say, but pretty much guarantee this is a hoax.

Here is what someone with audio software had to say:

I am not in favor of spreading hoaxes, and this is one; nevertheless the sound is nice.
Text says that it is the sound of crickets "slowed down to the lifespan of a human". As a cricket lives few weeks to 1 year, I slowed the sound by 100x, and I can ensure you that the result is purely inaudible, something between the airplane take-off and gurgling of a stomach. Just for fun, I will youtube the real sound "

Real chirps, and their awesomeness in function:
