Audio Question


George Stein - NJ3H
 

Greetings, 
 
The other evening I was listening to the Perseus live.  Due to the signal being weak I was using my headphones on VAC Line 12.
 
I also was using SDR Console and listening to a remote receiver in New Hampshire tuned to the same frequency as the Perseus. The audio was on VAC Line 5 going to my headphones.
 
I was trying to compare what I was hearing between the two sources.  What I had to do was mute one and then the other to compare the reception.
 
In a perfect world, what I would like to do is have audio from one source going in the left ear and the audio from the other source going in the right ear.
 
So, I was looking for Line 12, left channel to my left ear and Line 5, right channel to my right ear.
 
Any ideas on how to accomplish this?
 
Regards,
George

install a mixer (voicemeeter or voicemeter_banana or voicemeeter_potatoe)

then you can route one signal to left and one to right ear (plus have a lot of other options)

if you add another receiver set that to centre (both ears) so 3 different "directions" to listen from

mixer soft has a gate ... so with some noise reduction added (to lower noise) plus the gate you can hear the strongest signal only ...

Yes George, totally agree with Sigi. You need an audio mixer to split the two VACs so left and right ear. 100% agree to use the superb free "Voicemeeter" mixer:

https://vb-audio.com/Voicemeeter/

In Voicemeeter, set first input channel to VAC12 and set it to A1 and pan left, second input channel on mixer to VAC5 and pan right. Set A1 output of Voicemeeter mixer to headphones. Done.

See attached picture probably makes it easier to see. See my notes in strange salmon pink colour!

One last thing to check. I got caught out by it on a my Windows 11 installation the other day but it's also on Win10 (and maybe even before that?).

Press "Windows" key on keyboard (or hit "Start"). Type the word "Mono" to take you to Mono Audio Settings in Windows audio settings. Make sure that the slider "Mono" is turned OFF.

Again, see attached picture.

A few components, some scraps of wires, some sacrificial audio cables, "any old plastic box or pill bottle", and a little soldering should do it nicely if you have a second sound card. Of course, matching the delays,s hich can be done, may have a heck of a learning curve and "SoundMan"/ (That's my partner's commercial tool for venue audio. Venue would be airports, store complexes, theme parks, and so forth.) It has a free demo mode that could allow you to (painfully) line up the audio in time. I am sure other solutions exist. SoundMan is so handy it's what I'd turn to. I'd also make a GUI tool for it. Um, it also needs Asio4All to work with a sound card.
