And if you're after on board mics then these Knowles ones might be interesting, picking up to 80khz at least

The current mic I'm using is one of these electrets

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.

Thanks. I'm away until next week but will try it when I get back

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...

Thanks for the reply. Yes, clearly a different product.

Thanks

I have a stereo injector and the smaller size of the zero is appealing. 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...
