Hi.
I am trying to use the loopback feature to time align my speakers and subs. The problem I was/am having is no consistency in adjusted measurements. So I decided to run several sweeps using the same speaker without adjusting the speaker time delay. Using the Impulse/overlay, this showed the sweeps moved each time on there own, which kind of explains why I couldn't get them to align.
I am using REW V5.20. I have set 'use loopback as timing reference' in the preferences/analysis. I am using a USBPre 1.5 pre amp. I have a loopback cable installed in this (i've used this set up a few years ago to time align using REW)
Is there something i'm missing here that's causing this error? Attached shows 3 impulse's. Each time it moved slightly
?
Edit. Just run some more sweeps and now I cannot alter the delay. Every sweep aligns with each other. As if loopback is switched off
