Blue or red pill?

You've just confirmed them by objective means. The 'glitch' within the first 20ms lies below -100dB.

 

Even if this were fed to the DAC (which it wasn't), are you saying I'd be able to hear this? Really???

No. The chart shows an average, not an instantaneous value.

The instantaneous value seems to be at around -80dB, 17ms or so into capture. Even if this were fed to the DAC (which it wasn't), do you think I'd be able to hear this???

Yes. No. Maybe. The problem is we don’t know. It requires speculation instead of actual objective findings.

No speculation required. The actual objective findings are:

 

- the digital recorder is not directly in the playback-listening chain

- the glitch, due to the digital recorder's auto-start function, has a max instantaneous value of -80dB at 17ms

- the glitch is totally eliminated by 20ms

- the glitch doesn't descriminate between A and B (in the ABX)

Where is the recording showing that the glitch didn’t occur in the listening chain? All I see is your assurances.

 

There are a number of recordings that show the glitch and another number that don’t. Mani, you are not going to solve the problem by arguing about it. There were flaws in the test, and this is just one of them.

Paul, I tested the Tascam recorder. The intermittent glitch is due to its auto-start function. Without the auto-start, there is no glitch at all, ever.

 

Of course the setup wasn't perfect. I don't live in a lab. I used equipment that I have in my domestic environment. You know, sometimes, all you have to go with is induction: take all the evidence at hand and formulate a reasonable conclusion. It may not be water-tight, but at least it allows you to proceed.

 

But it seems that you're not willing to do this. Shame, because it's unlikely there'll be any follow-up as a result. So be it.

 

Here’s a suggestion for next time: get someone in the field of conducting sensory experiments to design and approve the test plan before you start. There are a few such experts here and some on ASR.  An objective test doesn’t have to use perfect equipment but equipment must be tested and measured before the test so that there are no questions about what happened afterwards.
