Thank you John!!!

Thanks John. I also found out that by generating minimum phase with the average trace, it will also have an impulse response, and being able to generate spectrogram. How is that different to a vector average? And why is that multiple measurements from different position should be time align?

I can generate an average of several measurements, but can't generate spectrogram from that average of several measurements. The "Generate" button is grey out.

Is that possible to generate average spectrogram from multiple measurements?

Hi all. I am planning to build an impedance measurement rig, and I am looking for a USB external sound card / adapters which provide 2 inputs or stereo microphone inputs. Most of those available are only one input or mono microphone input. Any recommendation on any model or brand? I only found...
