Dear Antoine,
collect sound data (.wav) with the audiorecorder (audiomoth) of your choice.
Point the script https://github.com/kahst/BirdNET-Lite to the location of
your data storage (MicroSD) attached to the Linux machine,... (read more)
Were you ever able to get a Bioacoustics StackExchange off the ground? An annual retry? :) (read more)
furry "dead cat" covers and blimps work best for cutting down wind noise, and a very good spectral noise repair tool, though it's paid, iZotope RX8. There is a de-wind module, but you can also teach it what to repair. I believe Davinci Resolve and Adobe Audition might also have wind reduction... (read more)
I'm assuming that by "sort by frequencies" you mean the frequency of the call itself, not the frequency of the audio recording (for example, a call at 1KHz vs a recording at a sample rate of 48KHz). My recommendation would be to use R (seewave/tuneR) to generate mean spectra of the recordings (... (read more)
Hi Harry (and all)
Just wanted to share some potentially relevant papers that I've come across, in case you haven't found them already. Coming more from the ecology/conservation focused side of conservation tech, but potentially of use to see what's actually been deployed out there! ... (read more)
The BTO Acoustic Pipeline, to support the sound identification of bats, and other species groups that are recorded as ‘by-catch’ during bat surveys, including small mammals, bush-crickets, some speices of moth (with other taxa being added all the time) has been launched. The current focus is UK... (read more)
Hi Tom,
Not sure if it's too late but the Species+ database from CITES has an API: Species+/CITES Checklist API (speciesplus.net) (read more)
Hi Steph! It could be either - if there was anyone out there for whom this work would be a good fit for their current role, then that would be easy, but if they needed their time paying for then I have extra funds I can apply for, which I would feel fairly confident about. (read more)
Hi cosmicspittle,
Many thanks for the pointer, I shall discusss it with our local tech disussion group here tomorrow morning. One of the guy's, the PhD candidate in tehrapy audio analysis, will be most ineterested as well. Our project is indeed becoming ever more interesting, like an... (read more)
Hi Wildlabbers,
We've got a fascinating paper to show you, as shared with us by Claude Miaud.
This study looks at how amphibian species use wildlife passages beneath railways, and how the inclusion of acoustic enrichment (broadcasting species-specific mating calls in the tunnels... (read more)
I thought this article might be interesting to people in this group:
"It’s common knowledge that bats navigate and search for their prey using echolocation, but did you know that the ultrasonic chips made by different species of bats are distinct enough that they can be used for... (read more)

Hi all!
Yesterday I started compiling a list of bioacoustics software that I knew of: link. The list breaks software into groups by function (e.g. annotation, detection,... (read more)

Hi Isla,
Range at which animals hear sounds depend on 4 things:
1) the frequency (pitch) of the sound of interest. As a rule of thumb, lower frequency sounds travel farther since high frequency sounds are subject to more absorption transmission losses.
2) the medium in... (read more)

Hi. I'm moving a topic to this thread from the camera trap thread since it's more relevant here.
Discussion with Alasdair for context:

What frequecy are you looking to record, how long does the mic need to run for, what is the distance between the microphone and the "listening" site? As (unless I've missed something) an off the shelf radio microphone does exactly that job. (read more)
How about using Kaleidoscope and the cluster analysis tool? Works fine, and is super-quick..

Update
The current AudioMoth group purchase reached our stock level of 1550 devices, hence the campaign has closed early. We'll now set up the manufacturing run and update you shortly on our progress. (read more)
Please find attached, a short note wherein we propose 03 postulates of soundscape ecology. The focus here is in soundscapes than sound of individual species. Our ability to separate a given sound clip into its constituent components is presently limited.

Dear colleagues,
we are designing a study to document presence or absence of spider monkeys in forest fragments in western Ecuador. We aim to record occurrences using the playback method, but we are unsure about the best speaker device we should use. If you have had a... (read more)
