                The INMP441 delivers 24-bit data left-justified in a 32-bit slot, so
                a shift of 16 keeps the top 16 bits (unity gain). A smaller shift adds
                digital gain (14 = 4x) which helps with this quiet mic; the result is
                clamped to int16. Fingerprints are level-independent, but the RMS gate
                is not.
