ABSTRACT:
A system and method for calculating audio processing attribute in digital signal processing system are provided. A testing system generates a multi-channel test signal in which one channel is returned to the testing system and the other channel is sent to a tested system. The test signals are processed, mixed and correlated. The resulting differences in the correlated signals are used to calculate various processing attributes of the tested system.
