here is where I edited the two clips in, with one exclusively in the left ear and one in the right ear, then play them at the same time and alternating. I must admit they are exact, and what you say isn't exactly correct, actually. but still if youre editing audio like you would not be able to remove an um.. but note in this audio i posted, no audio is removed, theyre just synced up and panned and then alternated. so you can hear them up close and next to each other quickly for comparison. I think it is possible they did edit this. it seems the second one may be a tad bit like microsecond sped up too... but the waveforms are damn near matches considering one has an interrupter. I am still looking but I wouldn't say so quickly that theyre not the same.  here is my testing/analysys have a listen with earphones on....  https://youtu.be/Pl4s1UK7LG4
