For CW Skimmer, also check the VAC Direct I/Q Output to VAC in the Audio

Within CW Skimmer setup, do not check VAC 1 for Audio I/O.Put this to
your PC audio path, if anything at all. This is meant for monitoring the
output audio of CW Skimmer itself and really not

I think the NR is far more effective r on this version 2.0.22. Along with
many other items.
If you have audio crackling with the NR, many parameters can effect that.
In addition to the settings of sample rate and buffer size for the firewire,
try reducing the NR Taps in DSP Options.
With Windows 7 64, just installed the new SP1.
On initial installation and start-up of PowerSDR v2.0.19, I had very a high
CPU usage, like 80% cpu. CPU is usually around 15%. Swithing on Task
Manager, I saw that the CPU hog was the .net Runtime Optimazation Service.
After about a minute, the
Also be sure that your Sample Rate and Buffer settings in the Firewire
Driver and PowerSDR match up.You may want to try a lower sample rate
and/or higher buffer. Try SafeMode 1 also.

Make sure that the VAC Cable numbers match up correctly between the Virtual
Audio Cable Setup in PowerSDR and soundcard choice for audio output output in
WinWarbler, make sure it matches your VAC cable number choices. I bet you
