Hi, I have purchased an AudioMoth to detect the ultrasonic sound emitted by bats. And I would like to know how can I detect i) count number of bats ii) bats' flying direction.

I am doing a project to contextualize bat data through different actuators of Arduino. Using LEDs, speakers, motors, etc to visualize bat data. For example, if frequency = 45kHz, LED will light up; if more bats, the motor will spin faster, etc. How can I do that? And can I transfer the data live, and wireless, using a raspberry pi and upload it to the cloud? Again, how can I achieve that?

Finally, is there any guide to manipulating the bat ultrasonic wav. file to human audible sound or visualize through spectrogram? Any tutorial for that? I am trying to use Adobe Audition.

Many Thanks!
