option to connect 2nd virtual cable to SDR consiole

Charly DF5VAE
 

Hello,
May be I have not found an already existing option to route audio in SDR console to an external prg (other than CW skimmer) via a virtual audio cable.

Tried to activate VB-cable (in Skimmer setup) - but no success - unable to route that virtual audio cable to WSJT.
I can activate VB-cable only as autio output from SDR console (instead of loudspeaker or Headphone) and use volume control to adjust level, but loose my loudspeaker/Headphone then .

Question: is it possible to program a separate independant connection interface to use a virtual audio cable.

Tested FT8 via qo-100. Such test allows to check narrow band frequency stability and measure Tx-Rx offset in low Hz range without any Test equipment!.

With not more than 100mW uplink power (in shack) and 15m coax to Poty feed I manage solid FT8 copy in downlink (with 12Hz offset)
Amazing stability (using SV1AVN GPSDO) and beacon lock in SDR console.
Well done!

Hi Charly

I have requested multiple switchable audio outputs from Simon and he has it on his list.

In the meantime see this very useful prog (recommended by someone on here earlier...... apologies, no time to look to see who it was):
https://vac.muzychenko.net/en/repeater.htm

Allows you to select VAC or VB-Audio as output on SDRC then monitor that source in speakers/headphones. Very neat little prog from the author of VAC.

You can also "listen" to the VB-Cable or VAC in Windows Sounds Settings but it is cumbersome and not as neat.

Of course if you have two (or more) VACs each individual "virtual" receiver can have it's own destination. Many people here run like that with one cable to FT8 on one band, another to WSJT, another to speaker out etc. etc, all within the hardware bandwidth of the SDR of course.

no tzhere is no way in sdr console to have two outputs .. BUT

in windows you can set in the recording setup to "listen to this device" ...

means you can switch to virtual cable but still have the sound on the speakers

ps if you wanna use freedv or similar that option has to be switched off again!!

Hi Sigi

Yes, I mentioned that in my earlier reply, but Audio Repeater (also see earlier post) performs exactly the same function but in a much easier way without needing to get into the messy Windows settings.

I am not sure what you mean here Max. You can already select separate audio outputs for each receiver, if you have enough audio output devices to which it can be routed. Those are what you setup with VAC, VAB, various USB audio devices, and so forth.

a subsequent messages made it clearer. Windows does not really make this possible in a clean manner. Contemplate what slightly different audio sample rates might mean for two different outputs on one audio source. One or the other will lag the other more and more over time until skips and jumps are heard.

Thanks for reading ma question and proposing diffent solutions.
I use only one receiver on qo100 - (plus the default one for the beacon)
Seems the easiest way ist to try the "listen to ..device" proposal first.
Thanks and stay healthy .

Joanne...... Multiple outputs from one receiver. This would then remove the need for separate external techniques to monitor the output of the VAC etc, because one output could go to speaker, one to VAC etc.

This subject keeps coming up over and over again ("how do I route to VAC and listen at same time") so this would make it so simple...... Personally, I now don't have a particular worry. I have ways around it as described here in this thread, but Simon has said he already knows how to add it so why not make life simple if he is happy to do it?

in tx box we have the "monitor"

if clicking on "rx" would send the received signal to the speakers that would work (but it routes mic signal to speaker while receiving)

tx monitor can be left alone (send tx audio or the tune tone to speaker)

rx monitor should send rx audio ...

easy

i have another option :-)

i use dsp-filter (from makito mori ... look for mmana, mmsstv, mmtty ... and you should also find its audio dsp software)

that takes the audio (in my case from vac) and after filtering sends it to speaker

there are some nice filters already preprogrammed ... and you can built 6 user filters (i made 6 different noise surpression filters)

if you in ALL MODES use that filter in parallel you then have the audio on the vac line (towards your digimodes soft) and ... on the speakers (processed or not depending if on or off)...there is a trough option so no processing if you wanna hear raw audio

so ... it is near the same as using the audio repeater software ... besides it adds some nice filters in the audio chain :-)

THAT is a good solution ... works fine ... and does not eat up tooo much cpu power

I use VOICEMEETER
(8 inputs / 8 buses / 8 outputs mixing console)
You can send any virtual audio cable to any other virtual audio cable or physical output, change level, eq, etc…

Now that is a mind blowing software system. I watch both videos Dam.

I wonder how it handles slightly different clock rates without ticks. Resampling takes a fair amount of processing power.

Interesting.

You mention any virtual audio cable.  Does that include VAC as well as VB Cable?

Sdr console already does this.  Switch it to multiple receivers. I use 2 virtual sound cards to feed 2 different decoders.

Hi,

I have been asked for this - I know how to add it, I'll probably add this once 3.1 is released but may add as part of 3.0.23, I plan to release 3.0.22 later this week.

I plan a small interface window where you can assign VACs to RXs.

Hi George,
Yes it includes virtual cables, but they are fixed to some channel strips…
For full routing I guess you still need VB-CABLE or VAC.

Hi,

Video showing two different sound cards at the same time.

Please add a volume control for each sound card.
