How does the audio from Owl Sense compare to ECM microphones?
Hear it for yourself! Below, you'll find a comparison between Owl Sense and a top-tier ECM microphone rated at 80 dB SNR with a handheld audio recorder. While Owl Sense has a 73 dB SNR microphone, it performs impressively well. In fact, compared to other low cost ARUs like the AudioMoth, Owl Sense offers much cleaner audio. Keep in mind that the equipment used for this comparison costs significantly more than Owl Sense.
These 2-minute samples were recorded side by side in June in a quiet but very vocal Montana forest. The audio is unedited, except for normalizing the amplitude to more accurately compare the two signals.
