Hi Eddie,

>> Doesn’t the latency increase if I create only the Magnitude

No. On the Auto Mag tab you have selected a minimum phase filter response. This puts the FIR filter peak at time=0, which you can see on the Export tab and provides essentially no latency. Can I suggest you research FIR filter basics? We have a white-paper at

FIR Filter Guide

while you may find helpful. Also take a look at the tutorials on

FIR Filter Design Tutorials

>> I use 8 measuring microphones to average the response of the room.

The averaged measurement on the Import tab still looks too detailed to be useful. I’d suggest applying some smoothing, either on the Import tab or on the Auto Mag tab.

Best regards,
