Ah ha. Or you could use the old record two tracks, invert one, and play the sum. If its zero, there was no difference. If the result is all zeros, then there is no difference. Period, no need to waffle with "discernible" And if the difference is -100 dB down, its zero to me, even if its numerically not zero For the math inclined, we could calculate an autocorrelation between the two signals, it automatically adjusts for slight delays But then I'm an engineer.
