Additionally, they offer a wider dynamic range and a higher threshold for ... the price point as well as the inclusion of the MEMS microphones. The base audio quality without any enhancements ...
MEMS microphones with best-in-class audio quality specifications can deliver the required performance. Every microphone can record a range of sound pressure levels (SPLs); this is known as the dynamic ...
The sensing device is a MEMS microphone that outputs a pulse density modulated (PDM) signal. There are chips available to directly interface such a microphone to a USB port, but [Mahesh] found ...
