Does it happen when you are on battery power, AC power or both?
Try running on battery power. I have seen it happen quite often where you will get noise from the power supply in the audio interface. If that is the problem, there is a simple solution.
You could try recording for a few mins with it plugged in, wait for the noise to happen, then unplug it to see if the noise goes away.
Considering the circumstances -- a home studio where nobody is going to sue you -- I'll recommend trying an AC ground lift. 3-to-2 prong adaptor. Put it right on your computer's power cord. I know a lot of people that do it, including myself, and have never had any adverse effects.
Very interesting. And sounds alarmingly simple. I'll be dancing in the booth if it works!
Can't you have your software pass the input signal right to the interface's output (mixed with whatever's already recorded) and monitor that with some headphones while you're recording?Only super fast systems like Pro Tools HD make this a viable way to really record (32 samples of latency = 0.7ms @ 44.1) but for troubleshooting purposes deal with the annoyance so you can hear changes without having to hit play.
Hmmm. I'm not sure I understand. Nothing is "already recorded." This is one voice, on one track, nothing added (no plug-ins during recording). So there is no mix involved. I can monitor my recording just fine -- but the problem never shows up then. It only appears on playback.
