Posts like the above are useless. You lay claim to a list of qualifications about sound, sound recording, sound quality, etc., and then, in context of an opportunity to discuss the issue of the sound qualities of the videos in question, you give a one word reply that adds not one iota of substance to the discussion.
I'd almost be willing to bet that in some post or another, past or future, you are going to accuse me of "handwaving" now that you have clearly done exactly that in the above post.
Saying that what I have called attention to concerning the sound of the Dick Olvier video that can best be described as six seconds of noise, followed by a squeak, and interspersed with a thump, and then a diminution of the noise following the squeak, as being indicative of the quality of the sound recording device and the subsequent playback on youtube "nonsense" is, itself a nonsensical handwave that adds nothing to the discussion, except a bald-faced appeal based on a claim of authority.
