[PD] DC weirdness, any ideas?

[David McCallum]

All,
         I was looking at a diskwrite in Sound Forge of a set I did and 
noticed something really strange, and was hoping that someone here could 
explain it. If you take a look at 
http://mentalfloss.ca/sintheta/images/dc.png you can see there's some sort 
of weird DC increase near the end of the track (the scale is in minutes, 
btw, not seconds).

         My signal chain for this is a delay (infinite) -> LP -> EQ -> 
reverb -> compressor~ (set as a limiter).

         The delay is scrubbed and screwed with, so that every change is 
recursive in the delay line. Dunno if that has something to do with it, but 
near the weird DC part all I was doing was adding sound to the line.

         Any ideas? This totally baffles me.

David
