DIF-AUR Difference Auralization

The DIF-AUR module separates the distortion by calculating the difference between a test signal xT  and a reference signal xR after adjusting the gain and time delay of both signals. This auralization technique requires no transducer modeling but can also be applied for recording the output of device under test (DUT) in the small signal domain (reference) and in the large signal domain (test).  This is important for auralizing distortion generated by nonlinear cone vibration and impulsive distortion generated by a rubbing voice coil, buzzing doors, loose particles and other defects.
