47. Building an acoustic recognition database Tadarida-L (Toolbox Animal Detection on Acoustic Recordings

Sonochiro (Biotope) is ontwikkeld door Yves Bas maar is Tadarida-L gegaan. Aanbevolen door Petterson. Herkent 63%.

Studenten aan de UK Universiteit hebben Auto Rec hardware AudioMoth ontwikkeld (Open Acoustic Devices) een klein toestelletje dat flink aan populariteit aan het winnen is. https://www.openacousticdevices.info/audiomoth

BatIdent is het Duitse programma van EcoCops dat bij BatCorder hoort en dat erg goed scoort op herkenning (81%).

Kaleidoscoop op 71%, Tadarida is zeker niet slechter dan Kaleidoscoop als de opnamen maar goed zijn.

BatExplorer is het programma van de BatLogger en herkent 53%.

Tadarida-L (Toolbox Animal Detection on Acoustic Recordings) is HulpSoftware, Open Source een Toolbox, altruistisch geschreven door Yves Bas waarbij je zelf je eigen classifier software kunt schrijven. Het werkt adhv herkenning van signalen. Used for birds, bush crickets and bats.
Tadarida-D=Detection
Tadarida-C=Classification
Tadarida-L=Labeling

In other programs you can get one ID for a wav file but now it can give more IDs onthe sound events. You get a probabilty rating for the Identification. For the final output it will summarrie it. Currently the NIOZ database is not strong enough but NIOZ wants to have identification and position of the bats.

Stewart Newson Norfolk Classifier in Belgium and UK.
STewart heeft voor de UK een classifier gebouwd om de UK soorten te determineren. Classifier UK uitbreiden met BENELUX soorten en classifier leert van zijn fouten. Tadarida is zeker niet slechter dan Kaleidoscoop als de opnamen maar goed zijn.

De eerste lezing (vanaf 11.44 min) is door Johann Prescher & Dirk Oosterholt : 'Grootoorvleermuizen leggen grote afstand af door coulissenlandschap om in moeras te foerageren.'
Tijdens onderzoek naar effectiviteit hopovers als verbinding in coulissenlandschap voor Gewone Grootoorvleermuis werd ontdekt dat deze vleermuizen lange afstanden aflegden om te foerageren in moerasgebied. Tot voor kort werd aangenomen dat Gewone Grootoorvleermuizen niet zulke grote afstanden afleggen.

Bestimmung von Fledermausrufaufnahmen und Kriterien für die Wertung von akustischen Artnachweisen - Teil 1
The original FFT is processed every 0.67msec. If you use a zoom factor of 4, you only take every fourth sample. Thus, it needs four times longer until you have acquired enough samples for the FFT, thus 2.67msec. Now, the trick is that you do not wait until you have all the samples collected, but you allow for „overlap“ in the samples and perform the FFT with the same rhythm of 0.67msec. [please note that this also takes four times the processing power compared to non-overlapping samples for the FFT and also takes more memory]

I have collected more information on the ZoomFFT in this Wiki:
https://github.com/df8oe/UHSDR/wiki/...ode-=-Zoom-FFT

I am not experienced in programming audio library blocks, but my gut feeling is, it could be easier to just use a queue object from the lib to get the samples and perform all the calculations in the main loop and not inside an audio lib object (because there are different sample rates involved). However, for people also interested in using the ZoomFFT, if you design a specific audio library object, you will get much more credit ;-).

Best wishes,

BTW: this brandnew publication will rapidly become the professional standard for the identification of bat calls from spectrograms in Germany. Maybe it also helps others with ID of bats in Central Europe.

Bestimmung von Fledermausrufaufnahmen und Kriterien für die Wertung von akustischen Artnachweisen - Teil 1

=====================

A little off-topic, OK, but now that the bat detector works, you need some info about bats and their bioacoustical properties and how to identify them by their ultrasound calls.

This is the "bible" of bat bioacoustics, if you want to know everything about bats and their calls:

Barataud et al. (2015): Acoustic ecology of European bats: Species identification, study of their habitats and foraging behaviour. -
http://www.nhbs.com/title/199366/aco...-european-bats --> not only for european bat friends, the bioacoustics & methods section is universal

There are many many nice websites on batcalls, here is a subjective choice:

http://www.batcalls.com/

http://blog.batdetective.org/

http://www.batecho.eu/

https://www.researchgate.net/profile...ication_detail

If you live in the northern hemisphere, we are very near to the end of the bat season, before the bats go to their wintering grounds. But if you live in a city, it could be worth going outside when the sun goes down and try to detect the last bats of the mating season doing their courtship calls.

Have fun with the Teensy and with bat detection,

  • Who's singing? Automatic bird sound recognition with machine learning - Dan Stowell

    PyData London 2018
    Bird sounds are complex and fascinating. Can we automatically "understand" them using machine learning? I will describe my academic research into "machine listening" for bird sounds. I'll tell you why it's important, methods we use, Python libraries, open code and open data that you can use. Examples of the latest research, and a successful commercial recognition app (Warblr).

    Bats orthoptera sounds on Xeno Canto GBIF

    https://www.nlbif.nl/bat-sounds-on-xeno-canto-gbif/ On www.xeno-canto.org a large and diverse community, with professional ornithologists and sound recordists as well as “citizen scientists” and casual observers have brought together a truly global reference database of bird sounds, with over 660.000 sound recordings of more than 10.000 bird species. Over the years the website has become an indispensable tool for everyone interested in bird song worldwide. As an example a Google Scholar search turns up 3260 results (November 1st 2021). The collection is housed on a stable institutional IT infrastructure in the Netherlands maintained by the Dutch GBIF partner Naturalis Biodiversity Center.

    Communities of bat researchers and enthusiasts have steadily grown worldwide. Recently, research involving passive acoustic monitoring has surged. In fact a large portion of bat species are rarely sampled using other methods. Accessible, high-quality call libraries for bats sounds are vital for the field to progress. Currently no repository similar to Xeno-canto for bat sounds exists. For example on April 1st 2021 GBIF referred to 490 bat sounds, mostly from Europe and North America. With a larger number of bat species and recordings openly accessible on Xeno-canto, it will be possible to better train algorithms used for automatic species recognition. This will greatly improve our ability to generate baseline information on species diversity for many yet unexplored sites, but also to more effectively monitor bat species or sites of conservation interest. In addition, open access to bat vocalizations will stimulate research at larger geographical, temporal and evolutionary scales.

    This project will result in a stable repository for bat sounds (Chiroptera) as an expansion of the Xeno-canto collection on www.xeno-canto.org of bird (Aves) and grasshopper (Orthoptera) sounds. The sounds and metadata will be shared through GBIF and are also available through an API.

    https://github.com/visipedia/inat_comp/blob/master/README.md There are a total of 1,010 species in the dataset, spanning 72 genera, with a combined training and validation set of 268,243 images. The dataset was constructed such that each genera contains at least 10 species, making the dataset inherently fine-grained. The primary difference between the 2019 competition and the 2018 Competition is the way species were selected for the dataset. For the 2019 dataset, we filtered out all species that had insufficient observations. From this reduced set, we filtered out all species that were not members of genera with at least 10 species remaining. This produced a dataset of 72 genera, each with at least 10 species, for a total of 1,010 species. Our aim was to produce a collection of fine-grained problems that are representative of the natural world. We made the evalue metric more strict in 2019, going to top-1 error as opposed to top-3.
