Hello
I use Holmimpulse to make my time time alignment of my drivers. But today I bought a ECM8000 with an USB interface Tbone micplug. My probleme now is when I do 2 ou 3 measurements of the same driver , the offset is always different. The offset mooves at each measurement. When I use my old mic pluged to the RCA input of my PCI sound card, evething is fine, each measurement has the same offset.

Could someone can help me ?

Sorry for my bad english..................

I should have spend more time in english leasson when I was young,,,,,,,,

Yes the probleme is that the time domain,,, the pulse response slide at each measurement,,,,

Have a look on the curves, I write the same offset value on the 3 curves. Of course it's the same driver without moving anything.

When I use my other mic that is pluged to the soundcard, the 3 curves are totally superposed with the same offset value.
