[QUOTE="Demetri Evdox, post: 216832, member: 15696"] greatly appreciate the advice. so as far as timing goes is it as simple as adjusting all speakers except for the 1 with the longest delay time to the mix position (measurement position)? ie.. use smart to calculate delay with a TF measuring pink loopback against mic.. (find delay) .. then manually do the math and subtract the differences ? i did a test another way playing 1 frame of 1k tone from pro tools to each speaker and recorded it at the mix position 1 at a time.. slightly re-aiming the mic at each speaker.. then measured the offset from the ref track in samples .. then adjusted the delay to the 1 speaker with the most delay .. re recorded the pop again to all speakers and the start of the tone lined up, but then the waves would all drift out of phase on the recorded tracks that were starting off in sync.. does that mean I have a phase problem that an allpass filter would correct?
