[ardour-users] Short question concerning quality

I have had pretty good results going into a laptop with an iMic (USB.
It is inexpensive (ABOUT $35)and the noise floor seems to be okay.
BUT... it is not duplex and has no midi interface. Like most consumer
cards it requires some sort of mic preamps or the signal-to-noise ratio
sucks.  An option might be something like an m-Box, but now we're
talking low-end pro gear and some bucks -- $400 or more.

But it could also be noise from the laptop power supply - they often
put a lot of gunk on the ground which leaks into your audio signals.
Does anything improve if you try with the laptop running on battery?

If so, you might try something like the Ebtech Hum X.  (But I don't
know if they make a version for European plugs and voltage.)
