The sound of thunder without any rain or wind. Sounds really far away. Could be used as war sounds far in the distance too. Recorded from a storm simulator with the rain and wind sounds turned off and thunder sounds set to highest amplitude.
Field-recording in a quiet street in l'ametlla del vallès (barcelona, spain). Some bird sounds can be heard rather closely, dogs barking and cars passing by in the distance. Recorded with a zoom h4n on january 2017.
Birds singing and chirping at dawn in the suburbs, a few cars passing in the distance. Noise is a bit high. Recorded with zoom h6 with ms mic. Caught many kinds of birds in the distance, too, including a duck and a rooster.
