Using Matrix creater for Measuring Impulse Response in a room with sweep signal

[aligohar73]

I want to use matrix creator for measuring impulse responses, but the response is not correct. I record the same signal at the same time with Rode Omnidirectional microphone and that is working perfectly fine. When I try with Matrix Creator recording then output impulse response does not make any sense. Is there any processing inside (e.g echo cancellation) causing the problem.
