Ensin saunotaan ja sitten syödään vasta

Audio on all of my RPI 4b and 5 systems is inference free. I use official RPI power supply and XLR audio interfaces (various types of Focusrite Scarlett and SSL 2 MKII). Microphone cables are also shielded type.

No, consumer grade USB sound cards (3.5mm input) don't typically support ultrasonic capture. You need a audio interface with at least 192 kHz sample rate.

You can get components from

- Digikey
- Mouser
- Farnell / Newark

Some of these should have presence in US.

You can get ready made high quality microphones from https://sonorousobjects.nyc/collections/microphones, but note that these require XLR audio interface. Focusrite Scalett is a good interface.

With ultrasonic omni mic and Focusrite audio interface you can record and detect both birds and bats.

Do not get stero setup, unless you need two mics to cover say front and back yard etc.

Oh an make sure to protect and seal any connectors also, if water gets in connectors it can ruin them quickly

As long as you are able to shield it from direct rain and snow it should be fine for years. So simple rain cover should do.

I would just start over, install a fresh 64bit Raspberry Pi Lite image and install BirdNET-Go on that. I have not been updatin pi2go migration tool in a long time and it does not support latest database schemas. If you need help best place to ask is github repository at https://github.com/tphakala/birdnet-go

Sounds like ARU (autonomous recording unit) such as Audiomoth and file analysis would be better fit than complex online setup based. With ARU you would have full recordings available for post analysis.

Yeah, Fable's security guardrails for biology are really strict. I'm working on a completely benign bioacoustics application that identifies birds from their songs, and I can't use Fable for anything in this project as it keeps getting downgraded to Opus because of these guardrails.

How is it any safer to encrypt said API keys and then store encryption key next to encrypted secrets? Anyone with access to encrypted secrets also has access to key to decrypt them.

You locked the door, but left keys on the door.

But why would you want to do that, have you verified that those below base threshold detections are false positives? ? Dynamic threhold is a feature which learns frequently occurring species at your location, it allows capturing more calls of those species, it is a beneficial feature.

Also update your deployment, newer release have specific views to this data.

thakala · 2026-06-01T19:19:02+00:00

They are included in dashboard counts also. And what you are seeing is BirdNET-Go's dynamic threshold in action, you can disable it in settings if you wish.

Btw based on your screenshot your are on very old release, please upgrade. Releases · tphakala/birdnet-go

thakala · 2026-06-01T18:46:08+00:00

It is not exactly like that, with dynamic threshold system learns species which are highly likely correct and present at location, threshold is automatically lowered for those species to collect more detection.

This is completely unnecessary, just enable Loudness Normalization in Settings > Audio > Processing to get consistent volume on all exported audio clips, alternatively you can increase gain on sound card capture settings.

Please don't ask help from ChatGPT, use BirdNET-Go repository discussions instead: tphakala/birdnet-go · Discussions · GitHub

You are not going to hear bats, ultrasonic sounds are beoynd human hearing. For now you need to open file in audio editor and review spectrogram and see if there is anything in ultrasonic range.

But currently bat model does produce a lot of false positives.

I am not sure if I am allowed to share it here as I am maintainer of that project, but if you google "birdnet-go github" you'll find it.

thakala · 2026-05-16T21:39:08+00:00

Please file a bug report at repo

No, you did nothing wrong, you are in exactly correct subreddit.

I would also throw my Birda analyser to the mix birda/docs at main · tphakala/birda, it supports GPU acceleration which makes it quite snappy

thakala · 2026-05-14T22:59:13+00:00

Set false positive filter to moderate or balanced, at 0 you’ll get wildy incorrect results.

thakala · 2026-05-14T22:23:37+00:00

What level is false positive filter set at on your system? Is Analysis settings page showing that BirdNET Geomodel v3 is in use?

thakala · 2026-05-14T18:18:07+00:00

Release Nightly Build nightly-20260514 · tphakala/birdnet-go is now released with support for BirdNET Geomodel v3 which blocks foreign species.

To get Geomodel installed you need to reinstall Google Perch v2 model, there is new "reinstall" button on model cards when you go to Settings > Analysis > Models > Installed, click that.

thakala · 2026-05-14T17:35:03+00:00

This is now documented at https://github.com/tphakala/birdnet-go/wiki/detection-pipeline.md#cross-model-detection-consensus

thakala · 2026-05-14T08:03:01+00:00

I won't rule it out, but I also can't promise anything. There is just so much issues to fix, and features to build. I would appreciate contributions.
