Hi could anyone help please, I am trying to understand measuring the distance for reflection points. Attached is a sweep taken with the loopback in, it estimated the mic from speaker is approx 70cm, which is spot on.
So am correct in assuming the red vertical dash is the first direct wave from the speaker (0u being the speaker), this also tallies with my measuring tape. But when I measure from this to the first big peak, it says 1.649m - where should I measure this from; the speaker, or from the mic, and what is this spike, there is nothing around that is 1.649M away, this is where I am confused?
Any help much appreciated.
