Hello
With my GLC 300, I have 3 way car audio system that contains a DSP and amplifier (rainbow- DSP amplifier L8.2), which have only 2 input options: 6-channel high level (connected to the Original audio car unit) and bluetooth (can connected directly from iphone or PC with Rew installed).
If I play sweep from REW to check delay from speakers, I can not get accurate delays due to bluetooth latency.
The only solution is I play the sweep file from USB on the car MBUX unit, and immediately click on Start button on REW. To minimize errors caused by pressing Play on the MBUX head unit and the Start button on REW not being perfectly synchronized, I want to measure each speaker 5 times and then average the results to calculate the delay. From the settings window in the Measure section, I selected ‘No time reference’ under Timing. Which of the following three options should I choose next: ‘Set t = 0 at Peak’, ‘Set t = 0 at Estimate Delay’, or ‘Set t = 0 at IR Start’?
Could you give instruction to get right delay of each speaker in this case?
Thanks
