Yes and I do control channels via a DSP

I don't quite understand it. Can you please explain more?

I just noticed that too. Checked with polarity app and it says phase is positive. I tried reversing the phase through DSP and it sounded out of phase with that..

Thanks for the tips, John. Based on that, the rear right speaker took the longest to reach where the RTA mic is positioned (front right seat): Speaker | start time(ms) FR | 5.89 FL | 6.12 RL | 6.58 RR | 7.48 This is interesting because the measurement I took with plain measuring tape shows...

Ah, I got it now. Measurement Looks much better. However, the measurement from RR(rear right) speaker seems to be quite off as signal took the longest out of all other signals to reach the microphone. (car is right hand drive so the microphone is at driver's position). I tried those time delay...

Hi John, I have attached the mdat time alignment file using the acoustic timing reference option. I am using loopback of output 2 to input 2 as reference. What I don't understand is why the result shows as negative delay? I would imagine the reference signal should arrive before the actual...

Appreciate your tips, John. I also stumble on the time alignment topic. The measurement I took with my car rear right speaker indicates negative delay distance. My guess is the setting is incorrect, but I can't seem to figure out why. At the moment output 2 loops back to Input 2, RTA mic =...

Thank you, John. The measurement looks much better after adjusting the mic input. A couple of further questions: - Do you think the setup from RTA window looks okay for measuring pink periodic noise? - I have overlays of comparison between (green) line with mic calibration and (blue) line with...

Hello, Just started tuning my first car audio and this is probably a very noob question. Does my measurement via RTA look weird? It's almost completely flat from 20Hz onwards. Setup: ECM8000 RTA and BOMGE BMG22 for audio interface. RTA is connected to Input #1 Output #2 loops back to Input #2...
