How does Wildlife Acoustics' Song Meter Micro 2 compare to AudioMoth 1.2.0? Both offer lightweight, economical solutions for passively recording birds, amphibians, terrestrial mammals, and soundscapes.

But when it comes to detection, Micro 2 outperforms in critical areas, combining superior SNR and a flatter frequency to capture detailed soundscapes and accurate acoustic indices. And that’s not all. Read on to learn about important differences between the two acoustic recorders.

Why Choose the Song Meter Micro 2? Signal-to-Noise-Ratio (SNR) Charts

Flatter Frequency Response

Cleaner recordings.

The Song Meter Micro 2 combines low noise and a flat frequency response to capture accurate soundscapes and acoustic indices. By comparison, AudioMoth 1.2.0, with increasing high-frequency sensitivity and lack of anti-alias filtering, can result in recordings with unwanted noise and undesirable “hiss” caused by the microphone detecting its electrical workings.

Superior SNR

So you don’t miss a thing.

With a higher signal-to-noise ratio (SNR) across key biological frequencies than the AudioMoth 1.2.0, the Micro 2 is better equipped to capture faint or distant sounds.

The result? You capture more of what you want to record—specific wildlife species or soundscape features—and less distracting noise, making finding target species or sounds easier during analysis.
