OK I assume you are using http://ccrma.stanford.edu/realsimple/...

So it uses some form of correlation scheme then ? Does it account for system delay from the mic response ? Does it delay the correlation to match the first arrival from the mic ?
Also, does it filter out any late responses such as reflections etc ? I ask, because I am hardly seeing any reflections in my measurements whereas other tools seem to show me some ..

Is impulse response measurement done with adaptive filter ?
I am interested in learning how the impulse response is deduced/calculated. I am assuming that the sweep is fed through an adaptive filter that continuously adjusts to the error between the measured mic response and the adaptive filter output. Please confirm.
