[LAU] Syncing USB-audio devices?

[Rick Green]

Thanks, Geoff, for your description of the Guitar processor with USB 
interface.
   There seem to be a lot of devices hitting the market with standard 
USB-audio interfaces on them lately.  USB microphones, USB turntables, USB 
mixers, etc.  This is good, but I can't for the life of me think of a 
practical use for a single-channel USB device like this guitar processor, 
or a USB microphone.
   Each USB device would have its own A/D converter, running on its own 
clock, right?  So it would be an exercise in frustration if you were to 
try to record a simple guitar and vocal using a USB guitar processor/DI, 
and a USB microphone, right?  How would you deal with the inevitable 
clicks and pops?
