Our lab has purchased nearly 3,000 AudioMoth acoustic recorders in the past few years. Overall, we have found their performance for measuring species occupancy in the field to be roughly on par with both a human listener and other commercial recorders that we have used. For those who are interested in a more detailed look at the performance of these recorders, Sam Lapp has recently written up some results from his quantitative AudioMoth performance testing, including on and off-axis frequency response, the effects of different housing options, and the effects of attaching the recorders to trees.
