Ok, I just recently taped a loud rock concert and am seeing something odd I've never seen before...
AT933 (w/sub-cardioid elements) - concealed in the liner of a hat with one above each ear
Sound Professionals Battery Box (dual level controls with bass roll-off) - bass roll-off turned off
Edirol R-09HR (LIMITER: off, PLUG IN POWER: off, LOW CUT: off, MIC GAIN: L) -used LINE IN and had level set to 39
The audio turned out sub-par. Forgive me if I'm not using proper terms here - but when I pull the audio in to my editing software (Sound Studio 4 for Mac), usually I see the waveforms displayed on the center line for each track with equal amounts above and below the center line. For some reason, this time the main audio still seems to be along the center line with a fair amount dipping farther below it than above it (in the negative? direction). Someone suggested fiddling with the DC offset, but that shits the ENTIRE waveform up or down, moving the center above or below where it should be. Any clue what's going on here? See the attached image.
Also, here is a sample from the beginning of the show:
