I'm squeezing out another pre-launch episode to talk about asymmetric, or lopsided waveforms vs DC offset. Is a lopsided waveform the same as DC offset? I've noticed in some recent recordings I've done for a new online course I'm teaching that some of the waveforms are a little lopsided. This isn't usually a problem unless it's extreme where clipping could occur on one side of the waveform when applying gain or loudness normalization. For me, it was being caused by my dbx 286S audio processor in my recording chain. More specifically, it was being caused by activating the high-pass filter in the dbx 286S. I disabled the high-pass filter and it solved the problem. If you use the dbx 286S like I do and are seeing lopsided waveforms, this might be the solution you need.
