I am new to electronics and not sure how to handle an electret microphone with an R-PI.

I want to develop some active noise cancellation with my Raspberry (Model B). So I thought USB-Microphone would be to slow for achieving this. But I can't find a well written tutorial for introducing the electret microphone amp (from Arduino) to my R-PI.

Do I need further components? Someone can give me a detailed explanation how to use this microphone with R-PI and how to configure it? Or is this microphone a bad decision for my purpose?

    Hello and welcome. Please note that the Pi does not have the means to sample analogue signals. So you will need additional hardware to read the microphone - which is the point where one has to ask whether that offers benefits over the obvious usb-soundcard approach. Please check this out raspberrypi.stackexchange.com/questions/9618/…

If you have a USB microphone or sound card, start with that, you will probably find it doesn't actually use a lot of processing power to get the samples.

That way you can get straight on to writing your application!

Your best non-USB alternative is probably SPI, but that is not straightforward
