| I measured room impulse response by following this guide,
and I got the impulse response,
To compare the difference between the estimated room impulse response which is obtained by using matlab image method and measured room impulse reponse (Aurora-plug),
But I can see the difference between these two impulse response,
First, the estimated room impulse response (image method) has the small value
[-0.015 ~ 0.02]
and measured room impulse response (Aurora-plug) has the big value
[-0.5 ~ 0.8],
I wonder if the measured room impulse response [Aurora-plug] has a normalized value?
and If Ii is a normalized value, How can I get the non-normalized value?
I think it result of the [gain applied for rescaling]
Second, I convolved between the remasured room impulse response [Aurora-plug] and generated sine sweep signal , but the result of the convolved signal has a bigger value than recorded sine sweep signal,
I think that convolved signal and recorded sine sweep signal have a same value,
Thank you for reading this script,
Have a nice day!
