I have noticed with my Moogerfooger MF-101 lowpass filter that the negative half of the output tends to not only have a more rolled off shape but is typically about 6db or more lower in amplitude than the positive half. I noticed something similar, but far less dramatic, with the output of a Prodigy, so it might be an anomaly of the ladder filter.
Question here is, is there a way in an audio editor to only change the gain of the negative half of the waveform without affecting the positive half? I can't think of anything short of some complex sequence of events, like copying the entire recording into another window, raising the DC offset to clip the entire positive half then lower it back, and finally add that to the original audio clip(perfectly in phase, of course) for additional gain.
