When the air is dry and hot, insects (that i believe are cicadas) chirp loudly from every direction while being too small for anyone to spot. Their sound, to me, is a sign and reminder of the hot, dry air of australian summer.
Just relax. I give it finer resolution, 24bit, so that you can see the touch of breaking waves. Wave sounds are often accompanied by calls of seagulls, but this is with cicada. It is a typical image of summer in japan. At825 & mr-1.
Recorded with a zoom h4n on a hot summer evening at a rural southeastern iowa property in the us midwest. Includes several varieties of insect drones, male and female bull frogs, and distant thunder from an approaching storm.
