Here's an example of what you can (and I did) do with VAC: I remoted my station audio from the PC that is connected to my Signalink to my laptop that I carry around the house using IPSound. IPSound wants to attach to a sound card for input and output, just like DM780 (or Fldigi, etc.). Indeed, I could get it to work by attaching both IPSound and DM780 to my sound card. However I did not want Windows sounds going out on the radio and I wanted to be able to independently control the audio from the radio separately from Windows sounds. Enter VAC.
I created two virtual audio cables in VAC. In IPSound I assigned cable 1 to the radio output. In DM780 I did the same. Similar assignments were made for cable 2 for DM780 output via IPSound. Voila, it worked! Think of the virtual cables as being like patch points in a patch bay. The other cool thing is I used the Audio Repeater application that comes with VAC to monitor cable 1. This allowed me to independently assign a volume to the radio audio separately from the Windows sounds. If you need to keep audio connections between different audio applications (like IPSound and DM780, or DM780 and PowerSDR) separate from actual hardware, VAC works great. --- In [email protected], Andy obrien <k3uka...@...> wrote: > > I understand sound cards.
