Heres the recording I got last Saturday during the siren test at my house. You can hear 4 sirens the closest being half a mile away while the others are well over 1 and 1/2 miles away Turn your volume up. I don't understand it when I uploaded it to the computer it was very loud but when I put it on putfile It decreased in volume? oh well enjoy
