Your notes are wrong, sir ! I did some digital forensics. The REW filtered excitation was set to 1 kHz lpf, as part of the experiment. This sets a 1kHz high shelf filter attenuation for the residual audio and the TD+N graph. But @dcibel set a give or take 2kHz lpf for the 1kHz pre filtered...

Best regards, Bernd

@John Mulcahy : I think would be nice and useful to include the filter settings in the .mdat file, to avoid horrendous scenes culminated in #183 Best regards, Bernd

No, sir, you did not ! Period.

So virtually no LP/lpf was used in REW FSAF for measuring and generating my residual with the already LP filtered file. @dcibel Thank you for replicating my experiment. And a big thank you for publishing your residual audio. "Hidden" in red letters is my guess. (If you allow me to guess ;-) )...

Yes, sir No, sir This time it is more complicated ;-) Attached are two (FSAF residual audio) files: The "rew filtered" file was made with full range grey noise file set for excitation. The filters set in REW FSAW were: L-R8 hpf 40 Hz and L-R8 lpf 2kHz The "pre filtered" file was made with...

and now? you blame REW for revealing... you blame FSAF for revealing... what is next to blame? a switch... haha Wackelkontakt ...another thread cluttered with Wackelkontakt Not the switch? Not the "jig"? You definitely measured the tweeter output? - how do I know that's nonsense? ;-) Best...

@dcibel: I replicated your hpf results. It is Barkhausen noise elevating your high frequency in TD+N graph. Listen! @John Mulcahy: Sorry, i got lost in a kaleidoscope. Best regards Bernd

Yes - Harmonics (Distortion), IMDs and (Barkhausen-)Noise, like one would see on an spectrum-analyzer (on peak hold?), analyzing the residual audio (file). No, it is the transfer function of the DUT You all are stuck in e.g. Farina THD 2...9 get over that useless metric! Listen! Best...
