Anomolous Waveform Graphic Representation

[IronDioPriest]

I have been working with ProTools for years, and today I experienced something I've never seen before. I was recording a VO, and after the fella was done speaking, before I stopped recording, the waveform graphic displayed recorded, on-mic audio where there should have been only room noise. I noticed right away, and took a listen. The audio played correctly up through the moment he stopped speaking, and the room noise played back as expected; but there was obviously on-mic audio being shown in the waveform graphic.

Upon close examination, I noticed that the waveform graphic was repeating itself after a certain point. Even though the audio plays correctly, the waveform graphic shows a repetition.

I seperated and pulled the repeated section down to show it relative to the correct audio, and it is a perfect match, even though listening to it yields only room noise, as it should.

But then I scrolled out just one level, and that made this anomolous graphic change to what it ought to look like - a low-level line of recorded room noise.

Has anyone ever seen anything like this? It's no big deal, but I cannot for the life of me figure out how this could happen. Any idears???

Shameless *BUMP*

Am I the only one to have experienced this anomoly?
