Crickets in Takano Playground

Crickets at night in the trees andbushes between Takano Shrine and Takano Playground in Ritto City, Shiga Prefcture, Japan.

I recorded with an Audio-Technica BP4025 stereo microphone and an Olympus LS-100 recorder. For post-processing is used Audacity on CentOS-6 (GNU/Linux). There was a lot of traffic noise, so I applied a high-pass filter aggressively from about 3KHz. These insects sing at about 5KHz.
