Hi, The code handling the analog sampling of the microphones is in
e_ad_conv.c and e_ad_conv.h it is quite tricky and close to the HW periphery definitions of the microcontroller dsPIC30F6014A. The AD is stated to be 100 Ksps (kilo sample per second). Thus in theory yes you can sample at 50K. It is maybe worth to turn off all the rest you do not need.

I couldn't see anywhere in the code libraries where the sample rate is actually set. Does that mean it is fixed? Thanks, Jonathan
