Cool!
Are you sure?
Dear Andreas,
I am sure of nothing :-)
I have opened my eyes when logging in and have seen in red: armbian-config
There is an option “switch to another kernel”
Now I have 4.11.5-sun8i \o/
to be continued …
I could manage to install audiohealth with this tutorial on Raspbian Jessie with desktop. For the OS installation I used Etcher as described.
I had some minor problems
- while the
git clonecommand needs no special rightsapt installmust be done with root rights. So it would be nice to add this in the documentation for beginners - would be nice to point to the path where
cd tools/osbh-audioanalyzer/runs, I had to search some time for thetoolsdirectory
I installed Jessie with desktop to have the opportunity to make a quick web search or copy’n’paste the commands from the git website in the terminal window. But over all the Raspi “performance” is quite frustating. It’s and old model I had laying around, so I don’'t know perhaps it is better with up to date hardware. But for me it is not really fun and an additional reason for a webservice based version.
I had only tested the basic audio analysis yesterday, have to check if graph creating works also.
Hello Clemens,
I am connecting to RaspberryPi via ssh and OrangePi via serial so that it is easy to copy/paste the commands in the terminal from a more powerfull desktop computer.
Seems to be a better way, its a Raspberry Pi Model B 512 MB and it is slow with a GUI.
Hi Clemens,
thanks for giving the program a try!
Yeah, working on the old ones isn’t that funny compared to modern desktop PCs or servers with SSDs in our days.
We added an appropriate note to the setup documentation (see commit 3377fa99). While this is obvious for anyone working on Linux for some time, it is indeed a minor but important bit of information for beginners. Thanks!
We placed an example regarding the program invocation for doing audio analysis at audiohealth synopsis, which reflects the --analyzer parameter:
audiohealth analyze --audiofile ~/audio/samples/colony_before_swarming_25_to_15.ogg --analyzer tools/osbh-audioanalyzer/bin/test
Do you have an idea about how to improve this?
Sure! We are eager to provide this service to the community but currently there is no free time in sight for doing the work on a robust implementation, so we are looking forward to funding from the BOB project. If there are others willing to support us, we have open ears!
I tried to install audiohealth on a new Raspberry Pi 3 with a fresh installed Raspbian 8.0 / Jessie
I got this error messages:
pi@raspberrypi:~/audiohealth sudo apt install python-virtualenv python-scipy python-numpy sox libsox-fmt-all xvfb-run xauth youtube-dl

pi@raspberrypi:~/audiohealth $ virtualenv --system-site-packages .venv27
bash: virtualenv: command not found
Desired package is called xvfb.
Then install edited: nonsensepython-virtualenv; @Andreas uses this a lot, so he had this already installed, maybe that’s why it was forgotten in the mentioned apt command line.
Thanks @weef, that is was, now its installing. So we should correct the advice on GitHub - hiveeyes/audiohealth: Bee colony vitality using audio analysis. Applies machine learning algorithms in C++ from the OSBH project.
Think the other packages where not installed due to the wrong xvfb-run instead of xvfb
Got some output - but with warnings:

(.venv27)That is true - because of the first error in your screen log, nothing gets installed - the 2nd error is only a result of this; I missed that in my answer.
It actually should work. The error looks like it is coming from not having the osbh-audioanalyzer binary available at the given path “tools/osbh-audioanalyzer/bin/test”. We also improved the error handling and reporting per commit 33cff044, so you might want to check again with the updated version by issuing “git pull” before trying again. Thanks!
Noch eine kleine Frage: Wo finde ich denn die Grafiken zur Leistungsdichte, falls sie trotz des matplotlib-Fehlers generiert werden können?
Man gibt bei den entsprechenden subcommands (z.B. “audiohealth power”) die Ausgabedatei an. Siehe “audiohealth --help”. Dafür musst Du audiohealth per “xvfb-run audiohealth power ...” aufrufen, hier kommt also “xvfb-run” zum Einsatz, wenn Du das Teil “headless” betreiben willst.
Danke fürs Nachfragen, diese Information ist bisher noch nicht in der README zu finden.
I got still some erroes:

[...]Don’t care about these warnings and errors when running the “analyze” part of the “audiohealth” program. However, when trying to generate spectrogram and power-spectrum images, prefixing the command with “xvfb-run audiohealth...” might help for running the program in “headless” mode.
There might be other reasons, but i haven’t seen this error yet. But as others did already, you might find these hints useful and we would be happy about any feedback:
Hi Andreas,
I’d like to analyse .wav files from my beehives and have cloned and uploaded audiohealth 0.4.0 from github to my raspberry pi.
Would you be able to tell me if:
- there is a new version that I could clone? (current in github is 0.4.0 2017)
- Am I doing something wrong? Setup, permissions, error in command lines.
- do I need to do some pre editting to the samples ie (40sec samples, only bee sounds, no background noise)
Kind regards Paul
