I won't give you the fish right now because I think that you should try to at least try to throw out a hook before you get the fish.I have made a 3oc version of the sound and you can listen to it here
but try to listen to the original first
What do you think you hear
listen carefully and you will be able to hear the various components of the sound and then you will be able to better understand how to synthesise it
So first, tell us what you can hear
