Sounds plausible except they threw in the "...two miniscule pauses...each are 2 microseconds long." Even if you consider that the 2 microseconds could be a halfwave and we are looking at a response of 4uS on the tape, it would mean that the recording fidelity of the tape would need to be better than 250kHz. I can't buy that. 2 milliseconds I could buy. Maybe they misspoke.

I think they mispoke. 2 microseconds is imperceptible to the human ear as a "pause".

Without watching the vid ... yet ... is this about the pilot allegedly saying something in the name of Allah before nose diving the plane into the ocean? I heard a lot of people saying that after someone else says the military shot it down because they were having missile practice off the coast of Virginia and one got away from them.

It has nothing to do with what you can hear, it's the analyzing of missing data from the voice recorder. They believe the missing data segments coincide with the shorting of a power cable to the fuel level sensor in the tank.

That was the cover story. It wasn't a radar ghost, it was Obama bin Laden on his flying carpet shouldering a Stinger missile.

2uS on magnetic tape? I dare anyone to detect a 2uS pause on magnetic tape whether it is with any method you want. The tape response would have to be better than 500kHz actually.

I realize that and I wasn't disagreeing with you. I was replying to Corey that it wasn't about hearing anything. Even though in this case the "pause" wouldn't be detectable if it was 2 uS, longer ones that may be detectable by waveform analysis of the recording might not be audible. I agree, it can't be 2 us. Even 2 ms would probably not be detectable by just listening though.

That said, you'd have plenty of room on a video tape for that kind of response ;)

Yeah, with a spinning head. Indications were that this was an audio tape.

Yes, I know. Jesus, stop being so serious. You did say, "I dare anyone to detect a 2uS pause on magnetic tape whether it is with any method you want" though. But I know, can't admit you might be wrong, especially if it means a chick is right, when it comes to technical stuff.

It would hardly be a "pause". 2us isn't even out of tempo for speech is my point. Even if they saw the waveform analysis, it wouldn't be called a pause. It would be normal tempo of syllables.
