Open Acoustic Devices

We've released an Application Note describing our new external electret microphone that is available from our online store. github.com/OpenAcousticDe…

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/articl…

Happy World Listening Day! The World Listening Project invites artists around the world to submit media that draws attention to sonic environments as sites of meaning, memory, and care. There are plenty of scientists and artists that utilized the @OpenAcoustics AudioMoth & HydroMoth throughout the year such as Marco Barotti's Coral Sonic Resilience installation: vimeo.com/1039181409?fl=… #worldlisteningday

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/OpenAcousticDe…

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.

Introducing the 2026 WILDLABS Awards winners! 🎉 This year, 16 grantees were selected from 523 applications, our largest cohort yet. Huge thanks to our partners @Arm for helping bring game changing conservation tech ideas to life. Meet the awardees: wildlabs.net/en/article/ann…

The heat wave has provided a good test of our satellite-connected AudioMoth which uses an Arribada @arribada_i SMD Argos module to transmit live status information from anywhere on the planet.

AudioMoth 1.2 are now available on GroupGets! @groupgetscom groupgets.com/products/audio…

@tactiZity_ The geophone needs an additional small amplifier before the AudioMoth input. We'll be publishing the circuit in a write-up of the project.

@OpenAcoustics I am interested in Geophone. How do you connect it?

We are experimenting with connecting other sensors to AudioMoth to detect elephants. Two promising solutions are an SM-24 geophone and a buried piezo contact microphone. This is what they record when repeatedly dropping a bowling ball from a height of 1.5m at a distance of 100m.

The AudioMoth Configuration App version 1.12.1 is out now! If you previously downgraded to 1.11.1, don't forget to update and regain access to the GPS synchronisation features. openacousticdevices.info/applications

@RinglerMax @and1hill @ZSLWhipsnadeZoo @WILDLABSNET Getting closer. The first production batch of cases has arrived but we're looking at an issue with the crimping of the connector. Hopefully, it will be resolved in a couple of weeks.

@OpenAcoustics @and1hill @ZSLWhipsnadeZoo @WILDLABSNET "Before the end of the year" is rather over - any news on this front?

Testing the latest AudioMoth infrasonic developments for the WILDLABS Awards 2024 with the elephants @ZSLWhipsnadeZoo today. For project updates check out @WILDLABSNET wildlabs.net/discussion/wil…

We've discovered a bug in AudioMoth Configuration App 1.12.0. If you've updated to this version and plan to use the frequency trigger feature, we advise downgrading to version 1.11.1: openacousticdevices.info/applications Everything else works as expected and we'll release a fix soon!

A new AudioMoth 1.2.0 group purchase has begun over at GroupGets! @groupgetscom groupgets.com/products/audio…

@Guy__Bennett @ZSLWhipsnadeZoo @WILDLABSNET The case is designed to take for the AudioMoth Dev but could possibly be used with the AudioMoth 1.2 PCB with some modification.

@Guy__Bennett @ZSLWhipsnadeZoo @WILDLABSNET This is a Primo electret capsule with a custom mount that we'll hopefully be able to supply next year. An external microphone tends to be lower noise and also have better low-frequency response than the internal MEMS microphone.

@DocSlinky Thanks. It's always nice to get positive feedback.

@OpenAcoustics Did I tell you guys how good this is? We have a field grid of 40 moths and just swapping batteries and cards on a hike without a computer was a life saver

openacousticdevices.info/applications We've released a new version of the AudioMoth Configuration App (1.12.0)! This new version includes new GPS settings and a synchronisation tool. Update now, especially if you have an AudioMoth GPS Hat or GPS bundle!

@Guy__Bennett @Horsburgh2 @DurhamBirdClub Nice recording! You can also export videos directly from AudioMoth Play with the green camera icon.

This is a 30 sec video of the spectrogram of a Yellow-browed Warbler in Pier Head car park this morning. Overall it called 100 times in a 2.5 minute, non stop performance. Wonderful just to sit and listen. Put the volume up to hear it. @DurhamBirdClub

@TheTrueChazzyf @groupgetscom If the pin was in the wrong place then it must have been the wrong jack. The 3.5mm jacks supplied by @groupgetscom are the correct jack and will definitely fit. Other 3.5mm jacks, with different part numbers, are unlikely to fit or will have the wrong connections.

@OpenAcoustics @groupgetscom Thanks. I've already tried to solder on the microphone jack - that didn't work - the recommended jack type had one of the pins in the wrong place. Maybe I can find someone who is more handy than me with a soldering iron to help me - Id really like to use the GPS chip that I have.

If you already have an AudioMoth and want to get started with GPS synchronisation, then @groupgetscom have AudioMoth GPS Hats in stock again. groupgets.com/products/audio…
