Re: Audio injector zero kickstarter is live !
And if you're after on board mics then these Knowles ones might be interesting, picking up to 80khz at least

Re: Audio injector zero kickstarter is live !
Good news. I managed to find one of the old Cirrus cards to work with but they're difficult to find and can be tricky to set up.

Click at start of mic recording
Hello Everything seems to be set up and working well except I get an audible click when recording from my mic. It's a small electret soldered to a wire approx 30cm long connected to a screw terminal which I soldered to the board. The click lasts for approx. 0.75 seconds and then the rest of the reco...

Re: Audio injector zero kickstarter is live !
And the reason for it all - I do a few bat surveys for an ecology company (I work for a wildlife trust so do lots of wildlife work) and this detector seamed like a cheap way to learn more about bats - this type of kit usually costs a lot

Re: Audio injector zero kickstarter is live !
I'm new to it all really, but I found this detector and thought I'd try making it. It should probably more be called a recorder. It's likely to do various things, but the main one seams to be recording ultrasound (UK bats tend to be low 20kHz up to just over 100kHz but in the area I live they're gen...

However, I'm looking for something which can sample at the same rate (or faster) as the no-longer available Cirrus Logic card, which apparently supported up to 192kHz. The project I'm trying to make is a bat detector Any plans t...
