@dannad- Clearly, you don’t understand the function/choice/application of, "time windows", as regards separating impulse responses, reflections, freqs, times, etc, when using FFT algorithms. But then, no surprise! I don’t expect anyone of your ilk (Naysayer Doctrine adherents) to comprehend, assimilate or discover anything, that reflects a modern view of this universe, or-disagrees with your rhetoric. I never said the thread wasn’t about RCA caps, nor- did I dispute your proposed experiment. ONLY, that I never addressed the subject. Again: apoplectic, much? As for my tone; if it reflects anything but distain for those of your ilk, OOPS!
