This is a recording of traffic passing on a freeway. Used the voice recorder app on my Samsung galaxy phone to record this. It is an android app available on google play. After recording this I downloaded it as a wav file, then uploaded it to soundtrap.com. An online studio where you can record and create music using pre-recorded instrumental loops. Here I altered or distorted the sound of the traffic to make it a more ambient sounding loop. Giving it a drone sounding noise.
