an interesting insect* recording http://www.asondheim.org/cricket1.mp3 http://www.asondheim.org/cricket2.mp3 *might be amphibian but very doubtful unlike most crickets, cicadas, grasshoppers, these sound continuously, on- ly pausing with what seems like exhaustion. the sound is intensely direc- tional; turn 90 degrees and it disappears, even though we were within a few feet of the creature (which remained hidden in the bushes). now here we are with the semblance of a neuron; there are threshold firings that one might consider digital (sound on / sound off) but there's also a fine structure that i assume goes well into the ultrasonics, conveying coded information that's analogically based. this is similar to 'counting chirps to determine temperature; in this case, there are no chirp bursts and whatever's going on is invisible - and perhaps invisible to the insect that hears and responds, the insect that autonomically decodes and acts accordingly. again, any information you might have would be greatly appreciated. the sounds were recorded at ground level (dangling mono microphone) early night in aurora, colorado, early august.
