Nice episode!😊 Too bad my field recorder can't record any higher frequencies than 48kHz at maximum sampling rate (Tascam DR-44WL). I should be able to get some noises though.
yeah depends on the microphone you use as well - something that goes beyond the 20khz. If the onboard mics go higher then maybe you should be able to get some noctules or socials calls from the pipistrelle species :) otherwise just use a cheap bat detector and enjoy the claps
So the ultrasonic mics set to 192 khtz is that the frequency for bats? Do you have to speed the audio up post to reveal the correct pitches? (You know what I mean) I’ve got 1 sonorous objects ultrasonic mic… would that work on its own?
heya, really depends on the species. with echolocation calls different species occupy different spaces within the frequency spectrum. European bat species can go from 10khz to way up over 100Khz. So best option here is that if you have the equipment record the bats with the ultrasonic mic and a recorder that can handle at least 96khz (but i suggest higher sampling rate). Once home, you'll have to slow the audio down in order to hear the higher pitch of bat calls. You can do that by simply changing the sampling rate to 48khz or use a bat analysis software like Koleidoscope from Wildlife Acoustics (Lite version is free) and use their Time Expansion feature to slow it down by either 10x or 20x. I'll focus on this on the next talkie episode
Hey Andy, nice to see your actual face…. This video is fantastic… thank you
Another great video! Nice to see the human behind the channel as well! And again, those bat sounds amazing! Reminds me of the blippo box, hehe!
Thank you! They do offer quite a lovely playground of fun sounds to use! :)
