  Note that this is limited to Birds, Grasshoppers, Bats and Frogs.

  Still an incredibly exciting project, and I had a ton of fun listening to bird sounds from my home country. But if you came in expecting to listen to lions and elephants, you will be disappointed.

  This would have come in handy when a cricket was in my house and I was looking for sounds of cricket predators to entice it to leave my abode. Eventually I did find one on YouTube but it didn't work. Turns out crickets can't hear sounds, but do feel wind vibrations, which is why they stop when you walk near them.

  whats funny about sound is in an environment with multiple creatures it can be hard to isolate one from the other, but with visual pictures it is somewhat easy.

  in pictures you have a 2d projection of 3d information, with time as optional. animals dont have the same 3d position at the same time so its rare for one to be occluding the other in the projection.

  in sound you have to have time, sound without time has basically no meaning. but with one mic its a 1 dimensional signal varying over time, coming from a 3d environment. where creatures easily overlap each other in the time dimension.
