#AudioMo day23:

Did you know that there is hidden morse code all throughout Mike Oldfield's 'Tubular Bells' album?

Somehow, probably during the two-track mix-down stage of the album, the CW from a powerful, very low frequency transmitter about 37 miles north of the studio in which this album was recorded found it's way to tape. It's centered at 16 kHz, and so low in the mix that you can't actually hear it... at least, not without some help.

This is a very short, not particularly comprehensive demo using two different methods -- a pair of stock Reaper plugins and an SDR package to mostly isolate this morse transmission, which is heard throughout the entire album.
