Adjust the sample rate to 22.50 and you will hear the rubbing of the
insect's legs...



In adobe audition click on edit, go to adjust sample rate.( I see you use
audition from the screen shot provided)

noticed a series of ultrasonic calls in a recording I did the other day
at dusk in a scrub/juniper area near Donana, S Spain.

15-21 kHz (and above, obviously), they are strong and show a pattern. At
first I thought of a bat, but maybe they were done by an insect (?).
Similar calls appear often during summer so I would appreciate any
hint. Just curious.

Regards
