You may want to link the output of your SDR software with other signal processing programs.  There are at least four methods (and I would be grateful if someone who has used one or more these methods could please expand this sections).

 

Physically link the line-out and line-in ports of your sound card

 

Use the StereoMix function of your sound card

 

Sigi, DJ9BFC notes: Hello eddy ... if you did not tell that answer first ... I would have said similar (use stereomix).  For any application that can use the speaker signal in parallel ... example any packet, sstv, rtty whatever software ... then you can use stereomix (if your
system has it available).  For any software that works between and NOT in parallel (example any audio filter software liks dsp-filter from makito mori) you have to use VAC.

2 different things

  • FCD feeds I/Q to SDR software ... audio goes to speaker and in parallel to wsjt ... use stereomix if available use VAC if not.
  • FCD feeds I/Q to SDR ... sound is sent via VAC to dspfilter and then to speaker ... vac is needed cause the audio stream runs in series and not in parallel.

 

 

Use free software

 

There are a number of free programs which work like the VAC software listed below:

 

 

Use the Virtual Audio Cable software

 

There is Virtual Audio Cable software available which allows the output of one program to feed into another.  Here's a screen-shot showing HDSDR feeding MultiPSK.
