OK. But you should not plug USB audio devices into any kind of a hub connected to a USB port because it will cause performance degradation. Plug into an empty USB hub. The only hub you should use is a wall-powered hub to possibly provide “cleaner” power than the computer provides.
I forgot to mention this before, but it might be useful information (or just more confusion). I was under the impression that to record stereo tracks in Audacity, the mic should be set to “2 channel, 16 bit, 44100 Hz,” yes? As can be seen above, though, when the microphone is set to 2 channels, I get very imbalanced recordings from Audacity, and when I set it to 1 channel, I get roughly equal results instead.
The C01U is not a stereo mic as far as I know. In my opinion you should set Windows Default Format to 1 channel 44100 Hz, then in Device Toolbar , choose mono recording (and MME host as you have it already). Choose 44100 Hz project rate (as you have it already).
You could then make a proper stereo recording by recording another track then panning both mono tracks Left and Right as desired using the L…R slider on the tracks.
If you must make fake stereo out of a mono track, see How to turn mono into stereo other than just duplicating . At least doing it that way you control exactly what happens.
If the problem with not getting a decent level without distortion persists (after recording in mono and plugging into an empty USB port) then I think you should ask Samson about it. Audacity only records the signal you give it.
