I'm reasonably familiar with the concepts, having taken Syn-Aud-Con classes many moons ago, and having spent some time with the Easera Systune demo. I'm having trouble getting relevant data.
Lenovo R60 laptop running XP, USBPre2,
Mic in front of a studio monitor, input 1. SMAART's internal pink noise.
If I reference input 2, either using the USBPre's loopback or with an external cable, delay finder gives me .91ms, nice and repeatable, and transfer traces look great. If I reference the generator directly, delay finder gives me something random between 30ms and 200ms, and the transfer traces are junk. Nil correlation. Live IR shows a stable peak, just not placed at 0 degrees.
Switching either or both input and output drivers between Wave and ASIO makes no difference.
Playing other audio from the laptop through the USBPre and referencing input 2 loopback also gives me nonsense data in the delay finder and Live IR window, although the transfer data looks OK. So the only thing I have working is internal pink listening from outside.
What am I doing wrong?
