yeah, that might be the case but it might also be possible that they have an archived version of the show before it was lossy-encoded.

When and in which file do you say the deletion is made to hide the mp3 ugliness? I think I am missing the point here..
Found the taper, but I doubt he is still using that e-mail account.
The best option left is I can get ahold of the other (incomplete) source..

it was just a guess that maybe the wav from the 1st post is a modified mp3, or maybe recorded at a really low sample rate... it is terrible, whatever it is. really hard to say for certain, I'm just guessing at how it could have become like that.

I'm getting confused now too, but #4 is clearly lossy for sure and should not be traded.

no, not that I've ever seen, anyways. when the cutoff is straight across like that I have always found little blocks inside. a good FM cuts off at about 15kHz but it is not so perfectly straight, looks like it has a bit of "stubble" at the top and, of course, the carrier (red stripe) hovering above. find an old show (pre-1990s) that is a good source from FM and take a look you will see what I mean.
