Why is a smart mic important? For starters, in the consumer market a smart MEMS mic is optimal for high-end audio capturing applications/products like conference phones, studio mics, DSLR cameras, smartphones, tablets and headsets. The "smartness" of a MEMS mic will differentiate these products from their low-end (and low-intelligence) counterparts. But let's not stop with the consumer applications, smart MEMS mics can also find themselves in other markets including industrial, health/medical, military/public safety, security systems, and you can take it from there. (I actually encourage you to let your imagination run with it—going along with my mantra and vision of "MEMS frickin' everywhere.")
Before I go off into further imagining a world in which everything has MEMS inside—and everything and everyone is smart (thanks to MEMS)—I want to emphasize why I decided to write this story in the first place: I was awed by the beautiful, accurate sound that the MEMS microphone enables and what it can potentially unleash in the music biz.
When Rob O'Reilly demonstrated the ADI MEMS mic, he played a compilation of several musicians who recorded tracks at Cybersound in Boston using ADI MEMS mics, including Silvio Amato, Miguel Pessoa and Aaron Flanders. The sound was simple elegance. Rob also played a rap song by Boston rap artist MillyZ, who on the fly made up the song "Analog Devices' MEMS Mic Rap." Imagine what you would record if you had the intelligent power of a smart MEMS mic. I think it's time to get the band back together, dude.

MEMS microphones are almost replacing the condenser microphones. Mems can be integrated,compact and with stands more vibrations without performance degradation.Also they are manufactured within plus minus 3 db sensitivity which means less difficulty for the manufacturers to test their products for its uniformity. The analog devices makes it with 62-dB (typical) signal-to-noise ratio (SNR), 20-kg and 160-dB mechanical and sound-pressure shocks, respectively, and power supply rejection ratios (PSRRs) of 80 dB (digital version) and 50 dB (analog version).
I'm looking forward to improved feedback systems in noise cancelling headphones. Who knows, maybe they will be able to design a product that cancels noise over the full frequency range, not just "airplane noise".
I agree. I got the chance to test some MEMS microphones from Wolfston last year. I compared them to the standard Electret microphones and there was no comparison. The MEMS are far superior, lighter and more sensitive.
There is no doubt in my mind that Electrets are dead. If your product isn't using MEMS, then your customers will want better.
Just my opinion.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
