Page 17: Acoustic Measurement
COUSTIC EASUREMENT The Dirac Live Calibration Tool For miniDSP uses a set of measurements made in your listening room to gather all the acoustical information about your room and speakers that it needs to calculate the correction filters. The measurements are made using the nanoAVR DL HDMI audio processor and a miniDSP UMIK-1 measurement microphone (must be purchased separately). -
