Locked Re: WebSDR for wsjtx... #GeneralGroupInfo

Hi Jim,
where sound card drivers provide a
"Stereo Mix" device it can be used but is very limited since all
audio sources are mixed together, you cannot easily choose what is
looped back to what.
On Windows VB Cable is a free option if
you only need one loopback. On Linux pulseaudio can easily be
configured with a null-sink device and monitors to build loop back
devices. On macOS I'm not sure there is currently a free option
without limitations but some cheap tools are available.
One issue with using webSDR receivers
is that web browsers tend to only send audio to the system default
audio device, that means that system sounds will have to be
disabled otherwise they will be fed through the loopback, and of
course will not be audible without the accompanying webSDR audio
stream.
Another issue is that most webSDRs when
listened via a browser will have latency in the audio stream that
approaches the point where decoders like the WSJT-X FT8 and FT4
ones are sub-optimal.
