In that part i forgot to change the recorded measurement signal so if you see a difference between the screen and your own set-up do not bother to tell me i know :-(.

In 1 part of the video you see a sub woofer measurement where i “find” the delay. If your dual channel FFT analyzer shows a negative time you need to swap the LFT & RGHT signals. 1/24oct 1/48oct or none smoothing is the preferred setting in that kind of a situation ).ġ channel is the measured signal (ISEMcon EMX7150 out of a matched quad set) and the other channel is the reference signal (pinkish stuff most of the time). Turns out that the audio quality is not the same as recorded so it will not look the same as in the video i’m sorry to say.(Still if you put the phase and magnitude smoothing on at 1/12oct or 1/6oct it will look a bit better but please try to not use that kind of setting in real live measurements.

You can hook up you measurement set-up and split the audio channels (LFT/RGHT) and rout them back in to your set-up for a transfer measurement. Please lower the volume on your audio until you’ve heard pink noise and set it to a sensible level (!:-). This is not lab situation and normally takes a bit longer then i did when getting the screen recordings. A smal example on working with in my case Smaart7.5.2.
