Before I go off to build my own...

I want to connect several microphones (MEMS microphones, but that's not terribly important -- it only really means I'm not looking for high-end audio here) to a Pi.

Using usb audio "cards" is not a good solution, as I lose all timing information, plus they eat up a fair amount of CPU that I need for real work.

I've found a couple of audio cards, but they all pay a lot more attention to having lots of output options, which I do not need.

Any advice?

Thanks

Just for anyone looking, I've found a current alternative:

https://www.hifiberry.com/shop/boards/hifiberry-dac-adc/

By default this has line-level inputs, but documentation is available on how to connect a microphone: https://www.hifiberry.com/build/documentation/using-dynamic-microphones-with-the-dac-adc/
