I'm trying to record a podcast and am having some annoying problem with what I can only describe as a crackle.  Only when I'm speaking it pops maybe every couple seconds.  I have turned the mic gain on the volume bar down almost all the way and it doesn't seem to matter where it is.  Mic is a plain condensor microphone element from radioshack I have running off of the computer voltage off the mic plug.  I do have pop filter material and have used this mic before on my ts-50 but it doesn't sound like that kind of pop anyways.  computer is an acer 5000 aspire.  running windows xp.  I'm using audacity to do the recording.  Anyone have any idea what to do to fix this?

You may have a DPC Latency problem.  Try running dpclat.exe from:  www.thesycon.de/deu/latency_check.shtml .  If the numbers run more than a couple hundred uSec it could be causing the pops.  Fixing it sometimes requires using a different sound card.

Try closing all the applications in the task bar except Audacity and see if that helps. I've used Audacity to record "voice keyer" messages for contests even on an old Pentium II computer and never ran into DPC latency problems. This was on a Thinkpad 600E, so that's going back a ways.
