Hay Peeps.
I notice this on microphones, and long runs of cables from amp line outs to my mixer, then recorded to the Sonar versions I have used...Periodically.
I have run over 50 low noise good quality braided cable through the dropped ceiling of my basement, to acoustic drums, and various amps, PA, and other instruments out side my booth...
 
I think it might be all those cables together in close proximity to each other or other magnetic or impedance causing the oddity of the redrawn waves.....Just guessing...In one test, I changed the overhead microphone , to another kind, non phantom powered, and that solved it for a few recordings....but it is back now....I do hear something not right if I listen solo to this sort of track if recorded slightly hot...So I reduced my record levels, and that makes it sound better in the mix, and redrwas look low but I do not see the oddity as you show  now...as the wave draws are not so wide anymore....and my eye sight is poor....wink.
