I was doing measurement for a new calibration file for Dirac Live. I was surprised by the graph (db level difference between left and right channel). When I created my filter Dirac applied a 3db gain difference between the channel. It sounded totally wrong. I took another measurement with REW, first making sure that both channel played at the same level (which they did, give or take 0,5 db). As you can see, the REW measurement is really strange ... Tried with different amp and speakers, same dip at 3500 and 11000. What could be the problem ? My Umik-1 mic ? Thanks for your help !
