I'm currently researching bat social calls (not echolocation calls) and have been given a series of samples (in .wav format) and wanted to know, if what I can hear is actually the social calls. Below is a Graph representation of the a sample from the data I have:
This looks fine to me. From this, I can clearly tell where the social calls are. If I play at the specific peaks, then it sounds like a bat "chirping" however, I've been told that social calls cannot be played back, and, therefore humans cannot hear them. I'm just trying to figure out what these noises, or, chirps might actually be.
Here is a link to the .wav file:
Thanks for your help :)
