I finally got a version of the anomalous record posted. If everything is
working right, it should be at http://tinyurl.com/y72chknu .
What I did was, I took the file I had and converted it to a 16-bit mono
file, then encoded that with FLAC. It's still 9 megs.
You should be able to easily hear the hum, and if you have a spectrum
analyzer, you should be able to see it at 57.5Hz with an add'l component
You should also be able to hear the music; it doesn't sound like an
acoustical recording to me, because I don't hear the usual horn
resonances. For that reason I favor the idea that it's an undocumented
experimental electrical recording, rather than a mechanical artifact or
something picked up in dubbing from a previous generation.
Let me know if you have trouble accessing the file. And let me know what
you think is going on here.
