Description
The STEVAL-MKI126V1 demonstration board
allows the connection of up to six microphones
using the sockets provided, or through the
connection of a dedicated six-microphone array.
The digital interface of the board allows the
interfacing of the MIC output to the most widely
used audio receivers and digital amplifiers, or
permits evaluation of the MIC with generic audio
measurement equipment. The filtered PWM
signals allow the connection of a headset to listen
to audio received through the microphones.
The fully digital path ensures a high level of
processing with sound preconditioning, filtering
and voice enhancement.
The main function of the STEVAL-MKI126V1 is to
convert the PDM signals from the microphones
into more common I
