# How do I input two mics simultaneously on a Laptop? To be able to input two mics simultaneously on a laptop, you need a **two channels audio interface with two mic inputs**. Using one interface for both mics will guarantee that both signal are digitized by a common clock, which is a must for your application. There are numerous options for such an interface, with varying prices, and specifications. Look for one with USB interface to your laptop and that is supported by your Windows 10 OS. # Can I use these MEMS mics Probably yes. Nevertheless, you have to setup the needed hardware to power them and convert their output to an appropriate signal to get into the mic inputs. That might imply adding components to have proper level and impedance. This question would probably be better answered on https://electronics.stackexchange.com/. The idea of using one of these with a combined headphone/mic seems just adding hassle and I wouldn't go this way. # How do I setup MATLAB to record/process the audio I don't use MATLAB and don't have a license to do tests. I would nevertheless expect that once your audio interface driver is properly setup on your laptop, this interface should be recognized by MATLAB. If this is not the case, that is an issue not related to sound design, and this issue should be dealt with either on MATLAB support forum if there's one, or maybe on https://stackoverflow.com/ where there is a [matlab tag][1].
