In the paper "AudioMoth: Evaluation of a smart open acoustic device for monitoring biodiversity and the environment", they talk about using a Goertzel filter for real-time classification to filter relevant sounds to reduce post processing and storage requirements.
I do not see this source in the github listed. (https://github.com/OpenAcousticDevices)
Could it be elsewhere? Does anyone know?
Thanks

There must be hundreds of Audio Moths in the wild now, and perhaps there are alternative versions of the code in use, but not a word of it on this forum! Is there another forum we should be participating in?
My Moths are collecting dust waiting for me to learn a LOT more about programming for signal detection, without ANY examples to work from...
It's a year and a half since the code used in the New Forest Cicada project was to be released 'very soon now'. I appreciate that research priorities are obviously elsewhere, and we're all under the pump, but isn't it time that the raw code, warts'n'all was released so those of us who really need this? The Open Source community doesn't sit on code, there's a community of enthusiasts out here keen to understand and improve it.
(Apologies for the tone, but I'd REALLY like to get on with this. If anyone has suggestions for how we might create a crowd-sourced & funded alternative firmware, I'm in.)
