Acoustic sensors enable efficient and non-invasive monitoring of a wide range of species, including many that are difficult to monitor in other ways. Although they were initially limited in application scope largely due to cost and hardware constraints, the development of low-cost, open-source models like the Audiomoth in recent years has increased access immensely and opened up new avenues of research. For example, some teams are using them to identify illicit human activities through the detection of associated sounds, like gunshots, vehicles, or chainsaws (e.g. OpenEars).
With this relatively novel dimension of wildlife monitoring rapidly advancing in both marine and terrestrial systems, it is crucial that we identify and share information about the utility and constraints of these sensors to inform efforts. A recent study identified advancements in hardware and machine learning applications, as well as early development of acoustic biodiversity indicators, as factors facilitating progress in the field. In terms of limitations, the authors highlight insufficient reference sound libraries, a lack of open-source audio processing tools, and a need for standardization of survey and analysis protocols. They also stress the importance of collaboration in moving forward, which is precisely what this group will aim to facilitate.

Audio Data Across Domains (AudioXD) Workshop

Great minds Alice!! I'd actually sent your workshop to justin separately this morning because of the alignment with audioxd.
As for joining things up globally, I think you're right. Looking at all that's happening in the bioacoustics community right now, seeing all these sort of events, what's happening with the bioacoustics stack exchange, and hearing the conversations that are happening - and it feels like such an opportune time to find a way to support all of these efforts link up and join forces. We have some plans on this front that will mean we'll be able to provide coordination support to help, and I'm interested to hear what people think is needed.
Steph
1 September 2022 3:21pm
Thanks Alice, and great to hear from you and Steph about the work that you all are leading. It would be great to follow up on the idea of doing more international collaboration in the ecoacoustics/bioacoustics space. If you're interested, feel free to drop me a line to catch up sometime about ideas.
Also, something of a side note, but we'll also have a Wildlabs blog post up summarizing the AudioXD meeting soon, hopefully.
26 September 2022 9:22pm
I love the idea of increasing international collaboration and inclusion within acoustic monitoring! I think there particularly needs to be more collab'ing between the terrestrial & aquatic/marine acoustic monitoring folks!
It would be great for more virtual/hybrid events to foster such international inclusion, so anything to facilitate that sort of online platform would be awesome!
There is also the new Bioacoustics Stack Exchange for Q&A. And the upcoming IBAC conference in Japan next October (2023).

You might check out the devices listed in the Conservation Tech Directory - you can search for 'acoustic recorder' or 'ARU' or something like that.
The most common off-the-shelf models (other than Frontier Labs' BARLTs mentioned above😊) are Open Acoustic Devices Audiomoths & Hydromoths (which may be particularly useful for you since they come in completely watertight cases that can be stuck underwater for deployments), Wildlife Acoustics' SongMeter series, and Cornell Lab of Ornithology's Swift units.

Camilo--
Are you interested only in airborne sounds or do you want to deploy hydrophones? That decision would inform a lot of other decisions about your purchase of equipment, as would having a clearer picture of your budget.
23 September 2022 5:39pm
Hi there Camilo,
What an interesting project! If you are looking for a lower cost, but effective tools for acoustic monitoring you might want to look into two options:
SoundTraps - are very commonly used and perform quite well:
SonarPoints - these are also a great instrument option:

Ah Journal club - this was a lot of fun but a little chaotic. We've been wondering if we should bring it back with a slightly different format. ie we all agree on a paper to read before rather than bringing a mix of things to present. What does everyone think? Is anyone else keen? Is there a format you'd suggest we use?
15 September 2022 3:49pm
I have been waiting for journal club to come back!! 10000% down.
I agree with @StephODonnell, would love it to come back!!! And now that variety hour is happening, that's more of the "mix of things" that she mentioned anyways so I think that new format would be great.
