Yes, clock correction exists to cope with differences between record and replay clocks.

You could place your mic a metre or so from a speaker and pointing directly at it and make some measurements to see if the variation is...

For comparison, 4 UMIK-2 measurements with acoustic timing ref made at my desk just now:

That's not what REW does. When using the acoustic timing reference (with clock correction) the stimulus consists of a timing reference...

The input from multiple sweeps is averaged before any processing happens, based on the number of samples in the stimulus, so the input...

Close. You don't need a timing reference to make multiple sweeps, but the input and output devices need to use the same clock otherwise...

REW does stop drawing the graph when harmonics reach their bandwidth limit. That graph is from a stepped sine measurement, so the...
