Hi folks: I'm down a weird rathole but feel like I'm so close to making this actually work. How did I get here? Well...

TLDR, I have a Windows Dev Kit 2023 box that's running a Snapdragon 8cx Gen 3 processor and has 32GB RAM and a 512GB NVME SSD built in; it's essentially the guts of a Microsoft Surface Pro X. It's running Windows 11 for ARM, which is MSFT's native aarch64 build of Win11.

On top of Win11, via Windows Subsystem for Linux 2 (WSL2), I'm able to run (via Hyper-V under the hood) an aarch64-native VM of Debian on top of Windows. Yes really:

So within said VM I have run the birdnet-pi install script, and I feel like I'm getting close to making the install functional...

But not without a couple challenges:

The Win Dev Kit 2023 hardware doesn't have a built-in mic or external analog sound card ports;
WSL2 on arm64 currently doesn't have USB pass-through capabilities from Windows to WSL2 VMs;
Therefore I have decided to make my USB microphone available to the BirdNET-Pi install via RTSP from Windows.

I had to fight my way through figuring out how to make ffmpeg + mediamtx/simple-rtsp-server work, but TLDR the config I am using is as follows:

paths:
  audio:    
    source: publisher
    runOnInit: ./ffmpeg.exe -f dshow -i audio="Microphone (2- AT2005USB)" -c:a:0 mp3  -ac:a 1 -b:a 320k -f rtsp rtsp://192.168.1.110:8554/audio

^ This reflects I have put the ffmpeg.exe binary in the Windows directory with mediamtx.exe; I have validated that with the above RTSP server running on the Win11 ARM host, I can use VLC on my Win11/Intel desktop on the same network and hear the stream albeit with a couple seconds of delay.

On the Windows side of the equation I set up a Hyper-V virtual switch in bridge mode so I could get an external IP to the WSL2 Debian VM. In my setup it's getting 192.168.1.11. The Windows host is getting an IP of 192.168.1.110. Network seems to be generally working fine.

However: BirdNET-Pi isn't yet working properly. In the logs I'm not seeing it attempt to record the stream; unlike when I was testing this on my Pi3B I'm not seeing it ingest the stream nor can I use the Spectrogram link (broken image, browser console indicates 404) so I think I'm not yet either running all services properly. Here's a few diag screenshots:

arecord not running seems like a tell-tale, but I'm not quite sure what to do about it. What I do see is BirdNET-Pi repeatedly open and then destroy the RTSP stream according to mediamtx:

Unfortunately it doesn't seem like much of anything is happening per the log (I do have config set to debug):

TLDR I feel like I'm super close to making this work! This Win Dev Kit 2023 box has a huge amount of potential, especially with its superior I/O & RAM available to it versus even the best RPis out there, so I'd like to get to the point where I can demonstrate this proof of concept as a success. :) Any and all help appreciated - thank you!

My amateur sleuthing through this led me to realize netstat -tulpn above isn't working because ... netstat wasn't present. apt install net-tools and voila - the script appears to be churning through the backlog...

The sheer absurdity of this post gave me a good laugh 😆. Thanks for that.

So BirdNET-Pi has a script that prints a ton of debug info, you can run it with the following command. You can paste the output back here and I can have a look to see if I get any ideas.

bash ~/BirdNET-Pi/scripts_print_diagnostic_info.sh

BTW - the path/command is incorrect, it should be:

bash ~/BirdNET-Pi/scripts/print_diagnostic_info.sh

Absurdity is my jam, so I'm glad at the very least another human also appreciates this ridiculousness. Thanks for your help @ehpersonal38 !

Here's the output of bash ./print_diagnostic_info.sh -

It turns out it does exist and is playable - as are another ~1200 .wav files also in the directory - and upon opening it I was treated to the sound of me hammering on my keyboard as the mic happens to be right next to my desk at the moment.

So the RTSP stream seems to be working and birdnet-pi is dutifully writing those snippets by way of I'm assuming ffmpeg as files to local storage...

Interesting... so I think the next place to look will be with the analysis server, since this is what kicks off the processing of your audio files. From your debug info above I see this

Here's the same output from my system which is working:

Of note is the fact that your analysis server has been running for over 3 minutes. This should never happen and indicates a hang. I would expect a runtime of < 30s on your system with a default recording length of 15 seconds. This hang seems to be preventing python3 /home/pi/BirdNET-Pi/scripts/analyze.py ... from being called, which is the actual command used to process an audio file. Hence the backlog of audio files.

So, I recommend editing the file ~/BirdNET-Pi/scripts/birdnet_analysis.sh, uncommenting set -x at the top of the file to enable more debugging information, then running the file manually and seeing what output you get. My hopes are that this will let us figure out exactly where the birdnet_analysis server is hanging.

Here's the output of running birdnet_analysis.sh manually after uncommenting set-x:

My amateur sleuthing through this led me to realize netstat -tulpn above isn't working because ... netstat wasn't present. apt install net-tools and voila - the script appears to be churning through the backlog...

I think that was ... mostly it. I stuck the mic out the window:

Now seeing some weird behavior with the spectrogram (possibly due to it continually opening & closing the RTSP stream?) - and the "Currently analyzing" seems to letter-box the spectrogram figures around a non-existent image, see below:

But this nevertheless seems like progress!

Can you try restarting all your services? (scripts/restart_services.sh). Your system was in a funny state for the past few days so that'll help clear things up. Let me know if it helps or not.

I have BirdNET-Pi set up in a proxmox container to a RPi 0W running a VLC audio stream. For some reason RTSP and RTP did not work but a HTTP stream did?? I googled and found this on StackExchange. I didn't have time to dig in and find out why but
cvlc -vvv alsa://hw:1,0 --sout '#transcode{acodec=mp3,ab=128}:rtp{mux=ts,dst=192.168.1.167,sdp=sap}' and
cvlc -vvv alsa://hw:1,0 --sout '#transcode{acodec=mp3,ab=128}:rtsp{mux=ts,dst=192.168.1.167,sdp=sap}'
did not work,
but this did
cvlc -vvv alsa://hw:1,0 --sout '#transcode{acodec=mp3,ab=128}:standard{access=http,mux=ts,dst=:8000}'

Hope that helps.

Just found an interesting series of pages around tensorflow & Debian indicating the tflite_runtime is no longer updated for Debian:
https://www.tensorflow.org/lite/guide/python

So just in case I followed these instructions to update the package:
https://github.com/tensorflow/tensorflow/blob/v2.5.0/tensorflow/lite/g3doc/guide/python.md#install-tensorflow-lite-for-python

Alas, no difference. I'm guessing your install script did this anyway. I also verified pandas was up to date via pip.

Hi again @ehpersonal38 - new random problem. I had to wait for parts to create a weather-resistant housing so I could put the mic outside...

However, now that I have the mic outside and the stream restarted, every analysis is coming back as Human:

https://i.imgur.com/pkVGoq9.png

I'm also listening to the stream from VLC and I can definitely hear birds, and not hear any talking. Any thoughts? I noticed this and then restarted the WSL2 Debian VM - same results over the past 10 minutes. It's a little windy outside but listening to the stream, I definitely hear birds.

Quick update: switching from the newer model in settings back to the older model, and then back to the new model again, seems to have un-confused the classifier.

That's an odd one, can't say I've ever seen that before. I tried both deleting my model/labels.txt file and also replacing it with a blank file in an attempt to somehow reproduce this and I was unable to. I'm happy to hear a simple swap back and forth between the models sorted it out though. Let me know if you need any other help, and good luck with your weather proof setup! (beats my method of just sticking my mic capsule out the window and praying 😉).

Hah! I had been doing the same re: sticking the mic out the window but my ADS-B antenna mast was right outside the window so I couldn’t resist. However -

Now that I have put the mic in the housing, my detection rates have dropped considerably…

I think looking at the spectrogram that there’s a rise in the noise floor perhaps?

I know very little about audio filtering but I wonder if I could apply something like a high pass filter to the RTSP stream via ffmpeg before birdnet tries to assess what it’s hearing?

Thanks for all your help! This is such a neat project & community.

It's a good idea, I had a similar one when I first set up my BirdNET-Pi. But ultimately I think it's more trouble than its worth to do pre-processing on the audio source, since the BirdNET model is trained on so many audio clips of various audio quality that it already knows how to handle whatever you throw at it. However, I can't say for certain. I know FFMPEG has a high pass filter, but I don't know if it works with a stream... Let me know if you decide to do it and what your findings end up being.

Best of luck with your BirdNET-Pi!
