AudioMoth - Big data software?

2018/09/26 12:02

What are other people using to shift through AudioMoth files to pull out the bats calls - so far I've settled on BatClassify. If seems to cope with corrupt/zero lenght files however it is very slow 10 hours for 5 nights on files and it is free....

Hi David, What is the problem you are having with zero length files? Alex

Hi Alex, I let the batteries get too low and I think that's what caused the zero length files - I didn't know they were there and one AI system I was using hit them and fell over. it was more I was intersted to know how others processed their big data - of course if/when the audiomoth can use a decibel trigger that will cutdown on the files :)

Hi David,

@hj.wood had a few suggestion on twitter that might be helpful?

This paper came out earlier this year using deep learning tools to detect bat calls: https://t.co/77ENdXt2Q3

I also just found this paper where you can extract bar calls and auto id! Anyone using it? https://t.co/5VOYyWO3XA

And @ollie.wearn is also using audimoths to monitor bats, but hasn't found an approach that could help. I imagine he's keen to hear if you find something that works.

Manually I'm afraid. Will be monitoring this thread for insights though

Have you made any progress?

I'm just an idiot in a dark field.... but as a i mentioned I use BatClassify by Chris Scott

https://bitbucket.org/chrisscott/batclassify

Now it is slow to run but I had a project where the audiomoth was out for five nights and from the output from BatClassify every file it flagged and I then checked with Spec - had a bat call. So I complied a list of IDs, then went back to site with several people using Bat Box Duet, Petterson M500 with Batsound Touch and an IoS Echometer Touch - got the same bat species.

AH, okay. Yes, if something goes wrong writing to the SD card during a recording, the file won't be closed, and so the file size won't be updated. Let us know if you get any zero length files in †he future since it shouldn't happend. We have another release of the firmware and configuration app coming out in a couple of weeks that makes the routine which writes to the SD card a bit more robust if something goes wrong, uses human readible long file names, and also adds local time to both the configuration app and the resulting time stamps.

Hi David,

Kate Jones suggested trying our their Bat Classifier tool - deep learning tools for bat acoustic signal detection. We've quite a few members here who worked on it if you've got questions (@Rory_Gibb , @snewson , @robin_freeman as a start)

We have a method for finding bat calls that is super quick, free and all code is open source https://t.co/52FPZHLyQU

How about using Kaleidoscope and the cluster analysis tool? Works fine, and is super-quick..
