I like to think of natural silence as the canvas upon which other sounds are painted. (Dr. Timothy C Mullet)
Here the recording of the grasshopper Ringed Bush-cricket, Rhacocleis annulata, first record for Northern Italy, which produces a call that is difficult to hear without the aid of a bat detector.
The first ten phrases using a bat detector; the second ten phrases using a Zoom H1 and an AOM5024 PUI microphone.
Below a recording using an ultrasonic USB microphone Ultramic 384k by Dodotronic.
For comparison, I also made a recording using a Zoom H1 recorder and an external DIY stereo microphone system with 2x Primo EM172 capsules.
Despite having a decidedly higher self-noise than the EM172 capsule, the 384k has proved to be more suitable for recording high frequencies, as it was likely to be expected.
note: I didn’t cut the passage of the car to highlight the difference at low frequencies.

I wish to thank my friends Cesare Brizio e Filippo Maria Buzzetti for helping me in recognizing the species.
Hey, thanks for sharing! It’s amazing! Could you please send me the original Ultramic 384k WAV sample to the email firstname.lastname@example.org? I’m looking for Sanken CO-100K alternatives for recording sound effects at maximum possible sample rate for pitching it down later. Thanks a lot! Cheers!
Best regards, Victor.
Hi Victor, I’ll send you via mail as soon!
Notevole, Marco. Bravo
