Ecoacoustics is a widely used wildlife passive monitoring discipline. Professional audio recorders offer robust casings able to resist adverse environmental conditions. However, the need of using clouds of recorders (for e.g. landscape level analyses) is obligating most researchers to migrate to low-cost devices, which unfortunately do not offer robust low-cost casings. In this work, we propose a home-made casing design and define a protocol of experiments for testing the recorder performance under real-life conditions. Specifically, we set-up an Audiomoth recorder for long-term wildlife monitoring in a Colombian rainforest and as a result, we find that it behaves similar to a professional SM4 recorder in terms of gain and dynamic range, and better in terms of soundscape information provided.
