A digital sound processing system suitable for use in a vehicle includes an interior rearview mirror assembly having a mirror casing having a reflective element disposed thereat. The interior rearview mirror assembly includes at least one microphone, with the microphone located at one of a rear portion of the mirror casing, a bezel portion of the mirror casing, a side portion of the mirror casing, an upper portion of the mirror casing, and a lower portion of the mirror casing. The microphone generates at least one signal indicative of a vocal input with vehicle cabin noise included therewith. A digital signal processor processes the signal and provides an output signal with reduced vehicle cabin noise.
