Consider adding decoding of FAX and DRM signals?

Could consider adding decoding of FAX and DRM signals?

You do realize that this decoding happens on the client side.
It's simple enough to feed the audio into a decoding program.

For me all decoders can be removed, even the FT8.

Specialized programs are far better and you only need to feed them the audio from the websdr to make it work.

Personally the only decoder that should work in the background, not visible for users, is WSPR.

There is WSJT-X and FL-digi that do a great job if you feed them the audio.

It seems that I need to add a virtual sound card and then export the audio to other software for decoding, thank you.

Exactly, as adding decoders will add a burden on latency, nobody wants that.

I'm afraid that this is not enough for DRM decoding. All my tries using different DRM demodulators and feeding them with the audio from VAC, have not succeeded. All we need is an I/Q output. I don't know if someone has the skills to code something like this.

Needs to happen in the front-end. Just like FT-8 is done at the moment.
But there shouldn't be a need for IQ, just raw audio either FM should be good.
Hoewever, making FM for SDR is difficult as it's not 'pure-audio' like all other modes.
