I have a question again:
As you know, above the frequency range of a sub, the phase trace becomes useless and looks chaotic.
In Smaart, for each frequency, if there is no coherence with the reference or if the signal level is too low, nothing appears — so you only see the trace in the desired range.
In REW, is there a way to manually or automatically remove all data from the measurement when the level of those frequencies is too low?
I guess I could use the EQ function and filter the measurement, but that would also modify the phase in the required frequency range.
I could also use the arithmetic function and multiply the measurement by a filter target, but the result would be the same.
I’m considering exporting the measurement as text and writing a Python script to remove everything below a specific threshold, but maybe there’s a simpler and faster way to do it?
