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.

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.

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!

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/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.

Yes, you can slow these down to audible frequencies and make a video of the resulting sounds.

It's not the best quality as I recorded it from your video, but it's not bad. You can downsample, play back faster or slower than real-time, and apply filters.

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

Using AudioMoths from @openacousticdevices.info we recorded vineyard soundscapes and then characterised them using acoustic indices

We showed that vineyards with higher bird species richness 🐦 had more diverse and louder soundscapes 🎶
