Observations by kjudge

Audio extracted from cellphone video. If you view the spectrogram of this recording using a short FFT window you can see the characteristic double pulse structure that distinguishes this species of ground cricket. Also note that there are Conocephalus fasciatus singing in the background, but they are virtually inaudible in this recording and only visible as a continuous broadband trill around 20kHz in the spectrogram.

Out with my son. Warning he shouts something at the end of the recording (I had to leave it in because it's so cute :) Note: if you download and look at the spectrogram you'll notice that there is something singing much louder up around 20kHz. That is probably the Conocephalus fasciatus which are everywhere. I may duplicate this recording for them later. Also, there are two male gray ground crickets singing, which slightly obscures the doublet pulse structure of their songs.
