Birdsong Visualizer
- junon 3y agoCan't really follow the instructions on mobile, is there a video or something?
- LesZedCB 3y agoif you enjoy this, the Merlin bird app is pretty cool - it will show a waterfall visualization so you can see the pitch changes. it also can identify birds in real time.
- eichin 3y agoWhat's particularly fun is that it's doing the identification by using machine vision techniques on the spectrogram. https://www.macaulaylibrary.org/2021/06/22/behind-the-scenes-of-sound-id-in-merlin/ https://www.macaulaylibrary.org/2021/06/22/behind-the-scenes...
- LesZedCB 3y agothanks, that's super cool, I had wondered about that!
- waingake 3y agoI've got a raspberry pi that records birdsong at sunrise each morning here for those interested https://www.mohiohio.com https://www.mohiohio.com Although it mostly recorded wind today. Scroll to get to another day. RSS feed available.
- da39a3ee 3y agoCool! Do you know the species singing fairly well, or do you attempt any automated identification? I've been dithering about getting a microphone that I could attach to my Android phone to do better at capturing quiet vocalisations (mainly thinking of that for use with Merlin. I do know the species here fairly well but still not certain of all vocalisations.) I've been listening for a few minutes. Really beautiful. There was an alarm call close to the mic that must have been a Turdus thrush but other than that I have little idea what I'm listening to! Guess: are drongos in there?
- waingake 3y agoI haven't attempted automated identification but I'd be keen to. Not sure where to start with that at the moment
- dekhn 3y agoI passed the audio through birdNET. Either posting onto the website at https://birdnet.cornell.edu/api/ https://birdnet.cornell.edu/api/ or just running locally via https://github.com/kahst/BirdNET-Analyzer https://github.com/kahst/BirdNET-Analyzer
- waingake 3y agoLots of Bellbirds in this area https://en.wikipedia.org/wiki/New_Zealand_bellbird https://en.wikipedia.org/wiki/New_Zealand_bellbird
- ngcc_hk 3y agoAny write up how it is being done?
- da39a3ee 3y agoThis looks cool but also not useful for ornithological purposes, right?

- da39a3ee 3y agoWe know they're not saying "...or I'll kill ya!" because conspecific violence leading to death is extremely rare / unheard of in most species. Or if they're saying it, it is not with any weight behind the threat.
- totetsu 3y agoI remember seeing a few years ago, maybe it was a landing page for a bird song data set, or classifier, a big grid of tiles of maybe spectrogram thumbnails of bird songs. Does anyone know what that was?
- selfhoster11 3y agoThere's a link to something like that in the instructions.
- atoav 3y agoBeautiful. I want to give out a recommendation for the python library librosa which can create similar visualizations (although in a cartesian space as opposed to polar coordinates)
