Recorded the 16th july 2012, 05:34 pm (unknown temperature, but hot, >20ºC, and windy) in a meadow with scattered Juniperus communis bushes. The recording has to be hardly filtered in order to take out the wind noise and other orthoptera species' songs, such as Platycleis albopunctata.
[It was used a FOSTEX FR 2LE field memory recorder, mode stereo BWF48/24 bits, connected to a an unidireccional microphone RODE NTG3 and a cardioid microphone SHURE SM58]
In the recording there are four sequences, and the end and the beginning of other two, lasting from 4 to 10 s. Maybe there were two or more males. The phonatomes are clearly isolated and fairly easy to count, and of similar amplitude. There are 260 phonatomes/s at the beginning of the sequence, which is at a low amplitude; both the amplitude and the rate increases (to 270 ph/s) as the sequence progresses, and ends abruptly. The peak of the frequency is between 12 and 19 kHz.
After a long echeme there is a pause and a short echeme of about 50 ms.There is a Tettigettalna argentata male singing in the background.
The figure shows the fourth sequence:
