Great paper describing how HydroMoth can be calibrated to provide SPL measurements accurate to 1–3 dB across a frequency range of 100 - 1000 Hz. journals.plos.org/plosone/arti...
Another AudioMoth deployment in our backyard 🦇🐿️ These field tests in different areas are mainly for testing a software I’ve created, wich will search and spot different bioacoustic sounds. Until now, it works 😄
The last update to the AudioMoth standard firmware (1.12.1) reduced the typical energy consumption of large SD cards. See our recent application note for more details: github.com/OpenAcoustic...
If you use the AudioMoth GPS Board or GPS Hat to synchronise recordings, you can now select between interpolation or nearest neighbour resampling algorithms when generating the final GPS-synchronised recordings.
The heat wave has provided a good test of our satellite-connected AudioMoth which uses an Arribada @arribada-i.bsky.social SMD Argos module to transmit live status information from anywhere on the planet.
Scientists have discovered hedgehogs may be communicating at frequencies up to 85 kHz. Set an AudioMoth to a sample rate of 192 kHz or higher and you can try listening in! www.bbc.co.uk/news/article...
Secret of hedgehog hearing discovered at far beyond human range
Researchers played a sountrack to hedgehogs to identify the frequency of sounds they can hear

There are currently a small number of AudioMoth USB Microphone boards and cases available at @groupgets.bsky.social. Inbuilt MEMS microphone and support for external microphones and hydrophones. Pair with the AudioMoth Live App to view and record live sounds. groupgets.com/products/aud...
AudioMoth GPS Hats are back in stock at @groupgets.bsky.social GroupGets if you want to start experimenting with sound source localisation from GPS synchronised AudioMoth recordings. groupgets.com/products/aud...
I (Peter) have been a big fan of @bennjordan.bsky.social's work for ages, so it was great getting such praise for AudioMoth in his latest video. A fascinating dive into bird vocalisation with some great advice for taking your first steps into listening to the birds around you.

If you want to do extended AudioMoth deployments with D-cell batteries, attach external microphones or use the AudioMoth GPS board, there are a few remaining AudioMoth Dev cases available at @groupgets.bsky.social. groupgets.com/products/aud...
There are a small number of AudioMoth GPS Hats back in stock at @groupgets.bsky.social if you are interested in trying out GPS synchronised recording. These solder to the top face of a standard AudioMoth. groupgets.com/products/aud...
www.bbc.co.uk/news/article... AudioMoth's humble beginnings involved a search for the New Forest Cicada. Great news to see the story coming full circle and the species returning to the UK.
If you are interested in connecting other signal sources to AudioMoth, such as piezoelectric hydrophones and contact microphones, or geophones, check out our new application note - github.com/OpenAcoustic...
This is a spectrogram of a selection of Nightjar calls taken with my Audiomoth and processed in Audacity, from the other night at Hamsterley Forest. It includes the 'churring, wing clapping and froggy croak calls. . @openacousticdevices.info #NEbirding
We had a fantastic day in the Canadian sunshine yesterday deploying @openacousticdevices.info HydroMoths in Lac Hertel, Quebec. There’s still a lot to learn about diel & seasonal trends in freshwater soundscapes… watch this space!
Today we're attending Biodiversa+ in Barcelona! Come by and say hi if you're attending.
If you use the AudioMoth GPS Sync firmware, there is a new firmware version and app out which better supports long recordings. Synchronised output files that were previously limited by the 4.3GB WAV file length limit will split into multiple files. www.openacousticdevices.info/gps-sync
GroupGets.com/hat 👈 The @openacousticdevices.info AudioMoth GPS Hat adds GPS time-sync to AudioMoth 1.1/1.2 via GPIO pads. Enables precise timestamps, delayed start, and optional microsecond sync with GPS Sync firmware.
AudioMoth Dev Case allows you to deploy an AudioMoth Dev with three D-cell batteries, a massive amount of capacity! Want to protect a device throughout a long-term deployment, or with a GPS/external microphone? The Dev Case is available now at @groupgets.bsky.social groupgets.com/products/aud...
if you see this quote with pics of your #AudioMoth deployment @openacousticdevices.info @tessarhinehart.bsky.social @wildlabs.bsky.social so we can imagine we're doing fieldwork instead of doomscrolling #bioacoustics #prattle 💬

GroupGets.com/micromoth ⬅️ @openacousticdevices.info MicroMoth is the world’s smallest full-spectrum acoustic dev board. Just 4grams, it records 8k–384kHz audio to microSD and runs AudioMoth firmware. Big performance, tiny size.
OK this is a real game changer thanks to @openacousticdevices.info and their play.openacousticdevices.info A different clip of yesterdays Tawny Owl file but in proper sound and sight #bioacoustics @stevechinnery.bsky.social you might want to check this software out
To protect them from curious elephants, we repurposed camera trap cages for our #AudioMoth Dev field trials as part of the @wildlabs.bsky.social Awards 2024. #bioacoustics
