First of all, thanks for the great hardware/software.
Not an SW/HW issue at its core, more like a question: do we have any technical details regarding on-board microphone, such as noise level, sensitivity, etc.? I want to use this board as a prototype for a project which performs some FFT/Wavelets/something analysis but I want to know the sound pressure level in decibels. Of course I can calibrate it against well-known device such as UniT SPL meter but anyway it would be better to know microphone parameters.
