Here is a new bat call recording from the garden of Schwetzingen Palace:

• MYsp_20140528_221241.wav

And here are a few screenshots of the sonograms in the Echo Meter Touch iPhone app:

Any hints regarding the bat species in this new recording are welcome!

BTW, regarding the following two old recordings I got the feedback, that the PLAUR one most likely indeed belongs to a Plecotus species. However, regarding the MYsp recording I received two different classifications, i.e. Myotis mystacinus (Whiskered bat / Bartfledermaus) and Myotis bechsteinii (Bechstein's bat / Bechsteinfledermaus).

• MYsp_20140521_221451.wav

Finally, I am looking for input which software I should be using for analyzing bat calls. What are your recommendations?
