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.
Try Kaleidoscope from Wildlife Acoustics: www.wildlifeacoustics.com/download
The free version does not time-expire and allows you to view spectrograms and change the playback rate of files to audio frequencies.
Hi, hope this might be useful for you. For visualizing spectrograms look for BatExplorer or use Audacity, also for manipulating sound files. For counting batch data hits, BatClassify
