<p>I don't know about other products, but we do have designed our own logger with audio/accelero/magnetometry, optimized for extremely low-power consumption. We have many current deployments different species of large or medium-sized mammals (from lions to lynx, although we still have to adjust our casing for the smallest species). We don't have a website yet so please contact me for details.</p>

<p>From my experience and understanding, most folks doing on-board recordings at that size (myself included) use custom built tags. I did purchase some Audiomoth µmoth but haven't had a chance to test them out.</p>
<p>Depending on your species of interest, the most important consideration is likely going to be weight, not size. Weight will be a combination of the components, as well as battery.

<p>The second consideration is how you will recover the tags. If it's for long-term deployment, you need a reliable way to locate the tags.</p>
<p>From an acoustics perspective, another consideration is whether you need your microphone calibrated or not, and conducting calibration if your sensor isn't pre-calibrated.</p>

<p>I am interested to know which small (&lt;3 x 2 cm board size) audio recording devices people have been using for on-animal acoustic tags (terrestrial) and what have been everyone’s experiences with them in terms of reliability, useful features, and drawbacks.</p>

(Asked by: username_0 on 2022-07-03)

I am interested to know which small (<3 x 2 cm board size) audio recording devices people have been using for on-animal acoustic tags (terrestrial) and what have been everyone’s experiences with them in terms of reliability, useful features, and drawbacks.

**Tags:** recording, biologging
