Earlier this year I participated in an EngineerZone Ask the Expert on the topic of Designing With MEMS Microphones. There, I answered questions about microphone hardware design, acoustic specs, data formats, connecting ADI MEMS mics to DSPs and codecs, along with many other interesting topics.
This Ask the Expert forum is closed to new posts, but a lot of good questions and answers remain there. You can browse the archived threads here. Of course, feel free to post any new or follow-up questions here in the EngineerZone Audio community.
