Loop Back Test

If they are out of phase they could sound more hollow or wider…but when summed to mono they will sound a lot weaker in this case.
See if flipping polarity makes them sound more natural/less wide.
But anyhow, it seems there is nothing unusual about the recording timing so it’s either just your perception of the delay that isn’t there or something else is causing it (accidentally set a track delay?..dodgy plugin?)
