I thought you could simply look at a waveform and tell if your input gain was too loud, causing distortion. Up until recently, this has seemed to work well, but for the past few recordings, I've noticed that I get distortion even when the waveform looks like it easily falls within the limits. Is this not actually a reliable indicator of a safe signal level, or am I possibly doing something else wrong? I'm using all of the same equipment. I haven't dropped the mic or anything. I'm singing in the same position/distance as always.
